Unattractive periauricular widened or hypertrophic scars can result from the tension on rhytidoplasty incision sutures. During a 5-year retrospective study, 10 female patients with such scars were treated with the periauricular ring technique. Polytetrafluoroethylene and double 2-0 mono nylon threads were used in 6 and 4 cases, respectively, introduced with a fascia lata non-bevelled needle . Following the scar exeresis, the borders were approximated and the ring tied and attached to the temporal muscle fascia.The outcomes were satisfactory. In 2 cases the threads were removed without altering the scars’ final aesthetic result.

Keloids were first described several centuries ago, however their handling and treatment are still often inadequate. A number of treatments are available, such as intralesional corticotherapy and compressive therapy. The case of a 24-year-old female patient with a 5 year history of keloids in the ear lobules, with recurrence after treatment, is reported. She experienced a full regression of the lesions (for 2 years) after surgical reduction followed by intralesional bleomycin injections. Bleomycin is emerging as a therapeutic option with few side effects and lasting results for keloids that are unresponsive to conventional treatments.

Introduction: Acne scars are common, and their treatment is challenging. Several techniques have been used to remove, reposition, and flatten acne scars to improve the appearance of the skin’s surface. More recently, fractional CO₂ laser has been used to correct such scars due its good results and shorter recovery time.
Objective: To evaluate and compare fractional CO₂ laser vs. dermabrasion-based treatment of acne scars.
Methods: Nine patients were assessed – six received fractional CO₂ laser and three were treated with dermabrasion. Subjective and objective parameters were evaluated for both treatment modalities.
Results: Both patient groups showed objective and subjective improvement.
Conclusions: This study has demonstrated that fractional CO₂ laser and dermabrasion-based treatments have similar efficacy in moderate to severe acne scars.

Fractional photothermolysis was developed as an alternative to ablative lasers (which are effective but pose a high risk of complications) and non-ablative lasers (which have limited effectiveness). Fractional photothermolysis has been successfully used in diverse dermatological conditions. This study describes the case of an Asian male patient with atrophic scarring secondary to trauma in the left paranasal region, who underwent treatment with 1,550 nm non-ablative fractional Erbium Glass laser, which led to a significant improvement in the lesion. This case corroborates the use of less-invasive procedures in difficult-to-treat dermatoses and in treating Asian skin types safely and effectively.

Introduction: The best option for treating distensible acne scars is cutaneous filling, however many such lesions cannot be seen properly under traditional lighting. Objective: To investigate whether an LED light spot helps in the technique of filling acne scars with hyaluronic acid. Methods: Twelve patients were treated with and without the diagonal and posterior focus of LED lighting. The patients themselves and two physicians deemed that the treatment has provided improvement. The median percentage of improvement attributed by the patients was 60% (without LED lighting) and 70% (with LED lighting). Results: The average median percentage of improvement attributed by the physicians was 55.0% / 65.0% (without LED lighting) and 70.0% / 72.5% (with LED lighting). Conclusion: The use of diagonal and posterior LED light spots enhances outcomes and patient satisfaction rates.

Introduction: With several treatment options available - including laser - atrophic acne scars are nonetheless difficult to treat. The use of fractional technology results in dermal-epidermal ablation columns, interspersed with intact skin islands, allowing selective thermal damage, effective treatment and faster recovery. The objective of the present study is to demonstrate the efficacy and safety of fractional laser use in the treatment of atrophic acne scars among the Brazilian population. Methods: An open, prospective, interventional study was carried out with patients with acne scars, without restriction regarding the gender and skin phototype. Exclusion criteria were: pregnancy, breast-feeding, presence of infections or blood dyscrasias and the use of anticoagulants. The evaluation was performed by comparing texture, appearance, and relief as observed in digital photographs. Results: Of the 30 selected patients, 24 were included in the study. An improvement was noted in the parameters evaluated in the cases that underwent fractional laser (CO2, Erbium-Glass or both). Individuals who underwent multiple treatments showed better results. All those treated with 4 sessions had improvements greater than 50%. Post-inflammatory hyperpigmentation was detected in 7 of the 24 treated patients. Conclusion: The present study showed that, when using appropriate parameters and adequate care, fractional laser-assisted resurfacing is an effective and safe method for treating atrophic acne scars in the Brazilian population.

Introduction: Acne vulgaris is one of the most common skin diseases and most often results in scars that are typically associated with aesthetic and psychological problems. To date, there is no standardized treatment for this kind of scarring. Objectives: To evaluate the improvement of distensible type acne scars on the face after treatment with the microneedling technique, followed by the topical application of a gel containing growth factors. Methods: Ten patients with acne scars who were treated from 2012 to 2014 and met the inclusion criteria were selected. All underwent 3 microneedling sessions with intervals of 1 to 2 months, with a 1-year follow up. Pre- and post- procedure photographs were carried out with a regular digital camera, and with a digital camera with a 3D system. Skin biopsies were performed prior to treatment, and 30 days after the last session. Results: Eight patients completed the study. Among these, seven showed a random reduction in the roughness of the scars in the analyzed area, seven showed a decrease in melanin with a homogenization of its distribution across the skin, and seven patients showed an increase in hemoglobin in the area being studied. The appearance of the scars varied among the eight patients. Deep ice-pick type scars did not improve with the procedure. Conclusions: The studied treatment promotes overall improvement in skin texture and a discreet effect on acne scars.

Inflammatory acne lesions may cause unaesthetic scars. Several treatments have been described to ameliorate its appearance. Will be described the treatment with subcision in two patients with acne and dystrophic crateriform facial scars. The female patient performed Microneedling in the same session of subcision. There was good clinical outcome in the treated areas of both patients after three monthly sessions.

Acne scars present at the end of the inflammatory phase of acne vulgaris have been treated with procedures that stimulate the production of collagen, such as microneedling. Six patients with acne scars were selected. Microneedling was performed with 2.5 mm needles. Subjective improvement was observed in all patients. In the technique of percutaneous collagen induction there is release of cytokines, growth factors and angiogenesis, with final production of type I collagen, making microneedling an excellent option for the treatment of acne scars, both for its cost/ benefit and for not drawing patients away from their daily activities.

Introduction: Acne scars result from inflammation of acne vulgaris and are a frequent cause of complaints in dermatology practices. Atrophic scars are the most common, and may be classified into superficial, medium, and deep. There are several treatment options for deep atrophic scars, however they have limited efficacy in general, undesirable side effects and are expensive.
Objective: To evaluate the treatment of deep atrophic scars with high frequency electrosurgery.
Methods: Ten patients with deep atrophic acne scars received 3 high frequency electrosurgery treatment sessions with intervals of 1 month. The following were used to evaluate the outcome 1 month after the last session: histological aspects of selected scars as compared to the baseline; ratings attributed to the results by the patients (worsened, unchanged or improved); and standardized photographs at baseline and 1 month after the last session performed by a physician not related to the study, who also rated the results (worsened, unchanged or improved).
Results: Histological analysis evidenced a reduction in local fibrosis. All patients noticed improvement in the lesions. The evaluator dermatologist physician verified the presence of clinical improvement in all patients.
Conclusion: High frequency electrosurgery is a straightforward, inexpensive and effective method for the treatment of atrophic deep acne scars.

Introduction: Acne is a multifactorial disease where inflammatory lesions usually appear as papules, pustules and comedones. It is more common in people aged between 11 and 30 years, and occurs in various body sites where there are high concentrations of pilosebaceous glands. Acne has different classifications and treatments. More recently, platelet growth factors have been used as an alternative therapy for acne scars.
Objective: The present study is aimed at describing a case of nodule-cystic acne and acne scars Grades 1, 2 and 3b treated with platelet rich plasma and highlighting the effectiveness of the treatment.
Methods: Platelet rich plasma was applied for three months in the left side of the face of a patient bearing acne.
Results: In the clinical and photographic evaluations, there was improvement in the skin appearance and quality, less number of lesions and decrease of pain.
Conclusions: The present study has demonstrated the effectiveness of platelet rich plasma as a treatment for acne and resulting scars.

Acne is a common condition that often results in scarring. We propose a novel treatment of acne scarring using: 1- chemical reconstruction of skin scars (CROSS), mainly with carbolic acid, 2- blunt bi-level cannula subcision, and 3- microneedling. A total of 139 patients were treated from 2017- 2018, of which 89 (64%) were Fitzpatrick Skin Types IV-VI. This triple approach to treating acne scars resulted in consistent high satisfaction from patients and photographic evidence of improvement. A combination of CROSS (to stimulate neocollagenesis), subcision (to release dermal connective tissue tethering), and microneedling (to stimulate neocollagenesis) is effective for acne scar treatment.

BACKGROUND: The microneedling technique and the transdermal drug delivery are indicated to treat acne scars.
OBJECTIVE: Evaluation of the microneedling technique associated with the drug delivery of the epidermal growth factor (EGF).
METHODS: Randomized double-blind clinical trial of 30 patients divided into two groups: (1) - two microneedling sessions with a 30-day interval, (2) - two microneedling sessions with the same interval but associated with EGF drug delivery. The patients were evaluated clinically (global acne scarring grading system - Goodman and Baron) global acne scarring grading system via multispectral image and through self-perception questionnaires. The statistical analysis (Student T-test, SNK test, analysis of variance) was performed with the SisVar software (UFLA, 1996).
RESULTS: The groups were homogeneous regarding age, gender, and phototype. Clinical assessments showed a reduction in severity scores for both groups. The multispectral analysis revealed a decrease in porphyrins (p = 0.0296) and an improvement in skin texture in group 2 subjects.
CONCLUSION: Microneedling therapy was effective and safe for the acne scars treatment, and EGF demonstrated to be a promising strategy as well.

Atrophic acne scars result from an abnormal wound-healing response that can be treated with microneedling (MN). Insulin may play a role in wound healing. The effectiveness and safety of combining MN with topical insulin as an alternative therapy for atrophic acne scar revision have not yet been widely reported. We report the case of a 33-year-old woman with an atrophic acne scar on the middle third of her face. The patient was treated with MN and topical insulin for four sessions at two-week intervals. MN plus insulin can be considered an alternative for acne scar revision.
