However, the seed cells of the dermal substitute are mainly fibroblasts. Chan HH, Lam LK, Wong DS, et al. Concentrations higher than 35% are not recommended because the results are less predictable and the potential for scarring is higher.9,20 The application of TCA to the skin causes epidermal cellular necrosis and necrosis of collagen in the papillary to upper reticular dermis, depending on the concentration of TCA.10,23,24, TCA application to the skin causes protein denaturation, the so-called keratocoagulation, resulting in a readily observed white frost.9 The degree of the frosting correlates with the depth of solution penetration. Punch elevation combines the techniques of punch excision and grafting without the risk of skin color or texture mismatch.2,12 This limits its use to shallow and deep boxcar scars.2 After the scar has been isolated from the surrounding skin, it is elevated enough to be slightly raised against the bordering tissue.6,28 Retraction of the grafted tissue occurs during the healing phase, resulting in a leveled surface.2,12, Punch replacement grafting. Graber The superiority of the combination was clearly evident in several aspects, including the rapidity and degree of improvement of the acne scars, fewer side effects, and shorter downtime.63, Epidermal substitute is made by adding epidermal cells to a scaffold to form a composite skin with some biological activity. In this prospective study, we evaluated the efficacy of AFR in the treatment of atrophic surgical and traumatic scars. Carniol PJ, Vynatheya J, Carniol E. Evaluation of acne scar treatment with a 1450-nm midinfrared laser and 30% trichloroacetic acid peels. As a result, it leaves behind. The first therapy consists of peeling with TCA, followed by subcision, the process by which there is separation of the acne scar from the underlying skin, and finally fractional laser irradiation. et al. Padova MPD, Tosti A. et al. An alternative approach that could be easier includes local activation and recruitment of endogenous stem cells to the site of defect for new tissue regeneration. A new technology utilizes a nonlaser device to generate plasma, a cloud of electrons, from nitrogen atoms, and a spark of radiofrequency.34 This technology uses pulses of ionized nitrogen gas to deliver heat energy directly to the skin.32,33,43 The epidermis initially is left intact, only later to shed as healing is completed.34 Roughly 10 days after treatment, fibroblasts depositing new collagen and elastin fibers can be seen. Hypertrophic scars and keloids resulting from surgery, burns, trauma and infection can be associated with substantial physical and psychological distress. Furthermore, 42% and 16% of the treated scars achieved a 76% or greater overall improvement according to 6-month patient and investigator scores, respectively. Disadvantages include erythema and discoloration.16, Pyruvic acid. 8600 Rockville Pike Similar to results from our previous studies15 and our personal experience, maximal benefit was seen 3 to 6 months after AFR treatment. Atrophic scarring is often an unfortunate and permanent complication of acne vulgaris. No bacterial infections or episodes of viral reactivation occurred during the study. Crusting/pinpoint bleeding resolved by 1 week in most of the patients, and only focal crusting remained in less than half of the patients. Pulse energies ranged from 20 to 100 mJ per pulse. Glycolic acids are systemically safe and nontoxic and produce superficial peels capable of significant effects, but with few complications. Fife D. Practical evaluation and management of atrophic acne scars: tips for the general dermatologist. Re-epithelialization generally takes 5 to 10 days, and erythema may persist for months.32 Side effects may include dyschromia (hyper- or hypopigmentation),9,32,36 infection,37,38 lines of demarcation between treated and untreated areas,32 and scarring.3638, Erbium: yttrium-aluminum-garnet (Er:YAG). In: Giuseppe MASaAD., editor. This may be useful for selecting the best therapeutic strategy, whether it be single or combined therapy, in the treatment of atrophic acne scars while reducing or avoiding the side effects and complications. Rongsaard N, Rummaneethorn P. Comparison of a fractional bipolar radiofrequency device and a fractional erbium-doped glass 1,550-nm device for the treatment of atrophic acne scars: a randomized split-face clinical study. Subjective investigator and patient ratings of improvement correlated with objective measures of improvement generated from the topographical skin imaging. CROSS technique: chemical reconstruction of skin scar method. AMBrightman S This is followed by collagenization in the healing phase and filling up of the depressed ice pick scar. CMeds. The disadvantages include stinging and burning sensation during the application, high concentrations not recommended in skin types V to VI, and potential for hypo/hyperpigmentation.22, Jessners solution. Epub 2018 Nov 9. Careers, Unable to load your collection due to an error. A 3-dimensional optical profiling system generated high-resolution topographic representations of atrophic scars for objective measurement of changes in scar volume and depth. Atrophic scars usually develop following an acute inflammatory process resulting in collagen destruction and dermal atrophy. El-Hadidy MR, El-Hadidy AR, Bhaa A, Asker SA, Mazroa SA. Weiss ET, Chapas A, Brightman L, et al. The injection phase with small parcels of fat implanted in multiple tunnels allows the fat graft maximal access to its available blood supply. It generates fractional deep dermal heating in the region of the electrode matrix to induce skin injury and then elicits a wound healing response, stimulating the remodeling of dermal collagen. BMBedi A, Baseline photograph (black outline). Alster More recently, fractional bipolar RF, based on the principle of sublative rejuvenation, which causes low epidermal disruption with high dermal remodeling, has been introduced to improve the efficacy and reduce the side effects of FP. Aims: We plan to prepare a review article about the indications of subcision, its adverse reactions, and pearls. GHGeronemus LaTowsky B, MacGregor JL, Dover JS, Arndt KA. He armed himself with a balaclava, latex gloves, condoms and Viagra pills and posed as a cab driver in a Mercedes to roam the streets of Brighton, East Sussex. Transdermal delivery of adipocyte-derived stem cells using a fractional ablative laser. government site. Posttreatment erythema, edema, petechiae, scarring, pinpoint bleeding/crusting, and dyschromia were graded (on a scale of 0-3) by investigators at 3, 7, and 30 days after each treatment and at 1, 3, and 6 months after the final treatment. Although improvement was noted with nonablative lasers, the results obtained were not as impressive as the results from those using ablative laser. Acquisition of data: Weiss, Brightman, and Geronemus. From the date of the first treatment to the final 6-month follow-up, patients were followed up for an average of approximately 10.5 (range, 8.5-13.0) months with no evidence of delayed pigmentary alteration. Massaki et al. The classification of peeling agents are listed in Table 1.18,19, Glycolic acid. An optical profiling system (Primos Imaging; GFM; Tetlow, Germany) allows high-resolution topographical imaging of cutaneous scars and calculation of quantitative volumetric and depth changes in atrophic scar volumes before and after treatment.16. Comparator scans were also taken from normal, unscarred skin. Although possibly less efficacious, we obtain favorable results using lower fluences for off-face sites, and patients prefer this trade-off to shorten the duration of posttreatment erythema. . Finally, needling is much less expensive to incorporate into a practice compared with a fractional laser or dermabrasion.1, Subcision is a procedure in which a needle is inserted under the skin and passed in multiple directions. The fractional bipolar RF device was also able to improve acne scars significantly.59, Punch excision. EMTanzi Atrophic acne scars are the most common type.1,3,12 The pathogenesis of atrophic acne scarring is most likely related to inflammatory mediators and enzymatic degradation of collagen fibers and subcutaneous fat.1 The most basic and practical system divides atrophic acne scars into three main types: ice pick, rolling, and boxcar scars. Baseline and 6-month posttreatment images of a surgical scar. The use of 40 to 70% pyruvic acid has been proposed for the treatment of moderate acne scars.9, The advantages of pyruvic acid are homogeneous penetration with uniform erythema, mild desquamation, short postoperative period, and the ability to be used in all skin types. Surgical excision of scars results in increased scar length and potential of worsening scar tissue. In: Zeichner JA, editor. Skin texture, pigmentation, atrophy, and overall appearance were evaluated after treatment and through 6 months of follow-up by the patient and a nonblinded investigator. Kauvar ANB, Warycha MA. B, Baseline topographical image with the scar outlined in red. Although not statistically significant, facial scars that were routinely treated at higher energy fluences (70 mJ per pulse) generally responded to a greater degree and had a more uniform response compared with off-face scars. Wrinkles and acne scars: ablative and nonablative facial resurfacing. First, fillers can be injected directly under individual scars for immediate improvement. A scar is usually composed of fibrous tissue. By 6 months, the trace erythema resolved completely in these 2 patients. Mature scars can be "normal," atrophic, or hypertrophic. 2023 American Medical Association. The duration of this therapy is 12 months. LJKauvar Clinically, atrophic scars classically appear as depressions of the skin and commonly occur post acne amongst other causes listed in Table 1 . Mild edema was noted in only 1 scar at 4 to 6 weeks after treatment 1. Four to 6 weeks after the second and third treatments, erythema severity was trace to mild (0.84-0.85). Author Contributions: Drs Weiss and Geronemus had full access to all the data in the study and take responsibility for the integrity of the data and the accuracy of the data analysis. In the next 1 to 3 days, a mild red-brown discoloration develops, and the skin feels tight. B Deep zones of ablation and coagulation produce robust dermal remodeling, tissue tightening, neocollagenesis, and, ultimately, clinical improvement in atrophic scarring. Scars may be formed for many different reasons, including as a result of infections, surgery, injuries, or inflammation of tissue. In addition, for these 5 scars, the maximum scar depth was calculated at baseline and at 6 months after treatment. Department of Dermatology, The First Affiliated Hospital of Nanjing Medical University, Nanjing, China, Glycolic acid, 30% to 50%, applied briefly (1 to 2 minutes), Jessner solution, applied in 1 to 3 coats, Glycolic acid, 50% to 70%, applied for a variable time (2 to 20 minutes), Jessner solution, applied in 4 to 10 coats, Glycolic acid 70%, applied for a variable time (3 to 30 minutes). VPKapadia The first look at the 'middle aged Love Island' set has been released, which has already been nicknamed the 'Viagra House' by locals after single parents searched for love With the fractional bipolar RF device, the RF current flows through the skin between the electrode-pin rows. Even after the surge . The objective topographical analysis of 5 individual scars substantiates the clinical observations reported by the patients and investigators. Ahmed R, Mohammed G, Ismail N, Elakhras A. Randomized clinical trial of CO(2) LASER pinpoint irradiation technique versus chemical reconstruction of skin scars (CROSS) in treating ice pick acne scars. In: Alam M, editor. Goodman GJ, Baron JA. Atlas of Scar Treatment and Correction Chapter Atrophic Scars and Stretch Marks Igor Safonov Chapter First Online: 01 January 2012 2695 Accesses 1 Citations Abstract Atrophic scars are the most numerous compared to others. The efficacy and safety of this method was investigated for the treatment of acne scars. Ice pick scars are vertical, "V-shaped", <2 mm depressions in the skin that can penetrate through the entire thickness of the dermis. . Our patient population consisted of 15 enrolled women with Fitzpatrick skin types I through IV, aged 21 to 66 years, who presented with 22 nonacne, atrophic scars between June 1 and November 30, 2007. SAlster A report about an ongoing trial of the drug from Raleigh-based Sprout Pharmaceuticals for treatment of low sexual desire in women finds in interim results that the so called 'female Viagra' can . On average, about 25 percent improvement of scars takes place with one session. The depth of the peel depends on the number of coats of solution applied. In this before-and-after trial, each scar received 3 AFR treatments and 6 months of follow-up. Atrophic acne scar treatment using triple combination therapy: dot peeling, subcision and fractional laser. Role of the Sponsor: The sponsor had no role in the design or conduct of the study; in the collection, analysis, or interpretation of the data; or in the preparation, review, or approval of the manuscript. Exfoliation then follows for 2 to 4 days, with moderate flaking. Before These MTZs are separated by healthy, untreated tissue and protected by an intact overlying epidermis. The site is secure. These wavelengths target the underlying water and collagen without disrupting the epidermal layer.42 Thermal damage serves as the stimulus for inflammatory mediator release, fibroblast activation, neocollagenesis, and dermal remodeling.46 The Nd:YAG laser requires more sessions (3-5 treatments per month for several months), but a patient can expect to see a 40- to 50-percent improvement in the quality of their scarring.42 The results are long lasting and continue well beyond the last treatment, indicating ongoing collagen remodeling after completion of the laser treatment sessions.47 This treatment offers significant advantages to patients in terms of its minimal recovery period and minimal risk of infectious and pigmentary complications.47,48, Diode laser. Overall, erythema tended to resolve more rapidly after the second and third treatments. Vejjabhinanta V, Patel SS, Nouri K. Laser for scars. Efficacy and safety of a single treatment using a 10,600nm carbon dioxide fractional laser for mild-to-moderate atrophic acne scars in Asian skin. Ablative fractional versus nonablative fractional lasers-where are we and how do we compare differing products? Arch Dermatol. Each scar received 3 AFR treatments at 1- to 4-month intervals. 2023 American Medical Association. Third, the recovery period of 2 to 3 days is significantly shorter than other resurfacing procedures. ODaniel TG. In: Nouri K, editor. TSProlonged clinical and histologic effects from CO, Alster Nouri K, Ballard CJ. Transient mild to moderate postinflammatory hypopigmentation/hyperpigmentation developed in less than half of the AFR-treated scars, but these pigmentary changes all resolved spontaneously by 3 months after the final treatment. Keloids occur in patients with a genetic predisposition and behave differently than hypertrophic scars, although there can be a. This phenomenon could be the result of a priming of the wound-healing response by the first treatment, but further research is needed to clarify this observation. At higher fluences, tissue ablation and coagulation extend beyond 1 mm into the skin; this deep thermal effect may produce more robust dermal remodeling and collagen production.17. TSTanzi Prevention and treatment of scars. La Operacin Deluxe tiene mucho -o todo- que ver con el final de Slvame, previsto para el prximo viernes 23 de junio. Bagatin E, Guadanhim LRDS, Yarak S, et al. Table 4 shows that the percentage of volume improvement in these 5 scars ranged from 26.8% to 57.5%, with a mean improvement in scar volume of 38.0%. Drafting of the manuscript: Weiss and Geronemus. The treatment of atrophic acne scars varies depending on the types of acne scars and the limitations of the treatment modalities in their ability to improve scars. Chapas Treatment of acne scars using the plasma skin regeneration (PSR) system. The https:// ensures that you are connecting to the Fifteen women with Fitzpatrick skin types I to IV, aged 21 to 66 years, presented with 22 nonacne atrophic scars between June 1 and November 30, 2007. Fifteen minutes before the treatment, each scar was wiped with a pad containing alcohol, 70%, and anesthetized with a combination of subcutaneous lidocaine hydrochloride, 1%, and 1:100000 epinephrine. Three-dimensional topographical images were taken of scars before treatment and after completion of the treatment series. Goerge T, Peukert N, Bayer H, Rutter A. Ablative fractional photothermolysis-A novel in skin resurfacing. Fabbrocini G, Cacciapuoti S, Fardella N, et al. The AFR treatment avoids widespread epidermal coagulation while generating zones of tissue ablation and thermal coagulation much deeper than those seen with traditional ablative resurfacing. MCGeronemus Shen Y, Dai L, Li X, et al. Think of a pothole in the road that isn't filled all the way upthat's what the imbalanced skin of an atrophic scar is like. it appears that PRP can improve the quality of atrophic acne scars treated with ablative fractional CO2 laser and decrease the duration of laser-related side effects including oedema and erythema. For the category of overall improvement, the mean 6-month patient scores correlated with a 26% to 50% overall improvement, and the mean investigator scores correlated with a 51% to 75% overall improvement. This impressive, uniform improvement across all scar variables is likely related to the ability of AFR to generate deep dermal ablation and coagulation to depths beyond those reached by traditional CO2 laser resurfacing. With varying success, numerous ablative, nonablative, and fractional devices have been used to stimulate neocollagenesis and dermal remodeling in an attempt to improve the appearance of atrophic scars. Use of l,320nm Nd:YAG laser for wrinkle reduction and the treatment of atrophic acne scarring in Asians. Density and depths of MTZs can be modified according to the desired clinical result. Harandi SA, Balighi K, Lajevardi V, Akbari E. Subcision-suction method: a new successful combination therapy in treatment of atrophic acne scars and other depressed scars. In this article, the authors review the different treatment options of atrophic acne scars. RRFractional photothermolysis: a new concept for cutaneous remodeling using microscopic patterns of thermal injury. Linear hypertrophic scar (e.g., surgical or traumatic) and widespread hypertrophic scar (e.g., burn or traumatic) are common . Facial skin rejuvenation: ablative laser resurfacing, chemical peels, or photodynamic therapy? Glycolic acid is the most commonly used alpha hydroxyl acid as a peeling agent.16,20,21 It can be used as a daily skin care product in low concentrations of 5 to 15 percent. At the final 6-month visit, patients rated 12 of their 19 scars (63%) as achieving a 51% or greater improvement, with 8 of 19 (42%) receiving ratings of 76% to 100% improvement in overall appearance. Acne scars: pathogenesis, classification and treatment. Each of these procedure has a different role in treating acne scars, with some modalities being better suited for certain scar types than others. From these measured scar volumes we calculated the percentage of change in scar volume from baseline to the 6-month follow-up visit. Er:YAG emits a wavelength of 2940nm,39,40 is 10 times more selective for water than CO2 laser due to its shorter wavelength, and reduces residual thermal damage.31,34,41 Er:YAG at 5J/cm vaporizes tissue at a depth of 20 to 25um with an additional 5 to l0m zone of thermal necrosis.31 The main difference is that energy from the Er:YAG laser more closely approximates the absorption peak of water (3,000nm), so virtually all the energy is absorbed in the epidermis and superficial papillary dermis. This degree of frosting is usually desirable for medium-depth peels, a full-thickness epidermal peel that heals after about five days. Stem cell therapy might have the potential as a promising therapy for atrophic acne scars in the future. An atrophic scar is an indented scar that heals below the normal layer of skin tissue. As a library, NLM provides access to scientific literature. In part 1, an overview of the importance of preoperative planning, intraoperative technique, and pathophysiology of wound healing is followed by a discussion of scar revision options for depressed/atrophic scars. Acne is a common condition that affects up to 80 percent of the adolescent population to some degree or another.18 It is caused and characterized by multiple factors including Propionibacterium acnes activity, increased sebum production, androgenic stimulation, follicular hypercornification, lymphocyte, macrophage and neutrophil inflammatory response, and cytokine activation.811 Inflammatory acne lesions can result in permanent scars.9 Scarring occurs early in acne and may affect some 95 percent of patients with this disease, relating to both its severity and delay before treatment.6 Acne scars can be classified into three different types : atrophic, hypertrophic, or keloidal. Laser therapy for acne. D, Posttreatment topographical image. A variety of effective treatments of atrophic acne scars have been developed. They are also well-tolerated by patients. To assess the safety and efficacy of ablative fractional resurfacing (AFR) for nonacne atrophic scarring. Each treatment area included the entire scar and the skin immediately surrounding the scar. With nonablative FP, despite the lack of tissue ablation, scarring can be moderately improved with a series of treatment sessions.13 An ablative 30-W CO2 laser (Fraxel Re:pair laser; Solta Medical, Hayward, California) combines CO2 laser ablation with an FP system in a treatment known as ablative fractional resurfacing (AFR). Potential patients were excluded on the basis of active infections or cancer, a history of keloid formation, allergies to lidocaine, isotretinoin use within the past 12 months, smoking, connective tissue disease, pregnancy, or cosmetic procedures in the treatment area within 12 months of enrollment. Pinpoint irradiation technique accompanied by needling is as effective as FP in the treatment of atrophic acne scars.53,58 It often induces microscopic thermal wounds to achieve skin rejuvenation treatment for ice pick acne scars. Further coats of Jessner solution create a level 3 peel, where there is prominent erythema and increased areas of frosting associated with a moderate amount of stinging. Both techniques are particularly effective in the treatment of scars and produce clinically significant improvements in skin appearance. It causes momentary, mild, tolerable burning on application, and no anesthesia is required. Lee JB, Chung WG, Kwahck H, Lee KH. Some of the grafts will heal in the same level of skin surface and some will be elevated.6,28, Fat is close to the ideal augmentation material in that it is cheap, readily available, and incapable of being rejected or causing allergic or other adverse tissue reactions.9,28,61 The technique consists of two phases: procurement of the graft and placement of the graft. If multiple procedures were combined, then many types of scars and fine textural irregularities would likely be improved to a degree that could not be obtained by each procedure alone. The procedure may be repeated two or three times at intervals of 2 to 4 weeks.17 The advantage of the CROSS technique is that since the adjacent normal tissue and adnexal structures are spared, healing is more rapid with a lower complication rate.17,25,26, Deep peels (phenol). Three other patients with type II skin experienced episodes of transient hyperpigmentation that resolved spontaneously within 2 months. Fourteen subjects were treated with an average of 4-5 sessions at 4-8-week intervals, with 12 subjects having >50% improvement. Further research into the most beneficial treatment intervals for scars on and off the face is needed. Based on anatomy, scars can be classified as hypertrophic scars, keloids, atrophic scars, and scar carcinomas. Scars may appear anywhere on the body, and the composition of a scar may vary. Various modalities have been used to treat scars, but limited efficacy and problematic side effects have restricted their application. Study supervision: Weiss, Chapas, Brightman, Hunzeker, Hale, Karen, Bernstein, and Geronemus. ANGrossman We believe that higher levels of coverage yield optimal clinical results for scarring. DISCLOSURE:The authors report no relevant conflicts of interest. Privacy Policy| National Library of Medicine A 3-dimensional optical profiling system generated high-resolution topographic representations of atrophic scars for objective measurement of changes in scar volume and depth. Yug A, Lane JE, Howard MS, Kent DE. Hedelund L, Haak CS, Togsverd-Bo K, et al. Fractioned laser skin resurfacing treatment complications: a review. Image analysis revealed a 38.0% mean reduction of volume and 35.6% mean reduction of maximum scar depth. Level 1 created with 1 to 3 coats of Jessners solution is very superficial and only causes mild flaking of the skin for 1 or 2 days or none at all. Eight patients underwent treatment on 1 scar, and 2 patients each had 2 scars treated. Hantash Deep peels may also be an option, but are more rarely used because of the downtime required for healing and the potential for complications and adverse events.12 Deep peeling solutions penetrate the skin to the midreticular dermis and create maximal effect for production of new collagen. For off-face scarring, higher fluences create deeper ablation and therefore may produce more tissue remodeling and clinical improvement. In addition, treatment settings for scars in darker skin types remain to be optimized. showed repigmentation of hypopigmented, atrophic surgical scars using a 1,550 nm NAFR combined with topical bimatoprost and tretinoin (2a) . This problem might be resolved effectively if the dermal substitute is used to cover the wound with a population of epidermal stem cells.65, The traditional concept of stem cell therapy comprises the isolation of stem cells from patients, propagation and differentiation in vitro, and subsequent re-injection of autologous cells into the patient. Pyruvic acid is an alpha-ketoacid and an effective peeling agent. In pinpointed irradiation, no complications could be seen as those with ordinary laser resurfacing and the downtime is shortened to 3 to 6 days. The remaining 12 patients (19 scars) completed all 3 treatments and 6 months of follow-up. Improvement in appearance of steroid atrophy at 2 months after placement of hyaluronic acid filler. Fifteen women with Fitzpatrick skin types I to IV, aged 21 to 66 years, presented with 22 nonacne atrophic scars between June 1 and November 30, 2007. This observation is likely related to the deeper levels of ablation and coagulation obtained with higher energy fluences. Second, volumizing fillers, such as poly-L lactic acid (PLLA) or calcium hydroxylapatite, can be delivered to areas where laxity of skin or deep tissue atrophy is accentuating the appearance of acne scars.1,3 Injectable PLLA is a biocompatible, biodegradable, synthetic polymer hypothesized to elicit the endogenous production of fibroblasts and, subsequently, collagen.5, There are many tissue augmentation agents that have been used in the past, but nowadays, because of the high incidence of side effects, the recommended material to use is hyaluronic acid.9 Hyaluronic acid derivatives potentially offer improved longevity of correction and reduced risk of immunogenicity and hypersensitivity.62 There are also indications that native hyaluronic acid promotes cell proliferation and extracellular matrix synthesis and modulates the diameter of the collagen fibers.63, Skin needling also called collagen induction therapy1,61 or needle dermabrasion is the technique of rolling a device comprising a barrel studded with hundreds of needles, which create thousands of micropunctures in the skin to the level of the papillary to mid-dermis.1,26 With this technique, the rolling is usually continued until bruising occurs, which initiates the complex cascade of growth factors that finally results in collagen production.4,9,26 Results generally start to be seen after about six weeks, but the full effects can take at least three months to occur and, as the deposition of new collagen takes place slowly, the skin texture will continue to improve over a 12-month period.9 The optimal scars to treat with skin needling are the same as fractional laser resurfacingrolling acne scars and superficial boxcar scars.1,4, Compared to other resurfacing procedures, this technique has many advantages.
