Objective: The present study aimed to investigate the efficacy and safety of pulsed dye laser (PDL) combined with fractional CO laser in the treatment of burn scars in pediatric patients.
Methods: The present retrospective study enrolled 60 pediatric patients with burn scars from July 2017 to June 2021. In the 4-month treatment period, all patients received PDL treatment every 1 month and received fractional CO laser treatment every 3 months. The Patient and Observer Scar Assessment Scale (POSAS) was used to evaluate the scar condition before the treatment as well as 6 months after the whole treatment. The satisfaction of the patient's parents was collected and recorded 6 months after the treatment. Complications were recorded during the treatment period and at follow-up visits.
Results: Among all patients, 38 (63.33%) cases were scald-induced scars and 22 (36.67%) cases were burn-induced scars. The mean diameter of the scar area was 107.53 ± 2.92 cm . For the measurement of the patient part of POSAS, all indices of pain, itching, color, stiffness, thickness, and irregularity, as well as the total scores were remarkably lower after 6 months of the treatment compared with the baseline (p < 0.05). For the observer part of POSAS, the indices of vascularization, pigmentation, thickness, relief, pliability, and surface area, as well as the total scores were markedly decreased after treatment (p < 0.05). The total satisfactory rate was 96.67% (58/60). No severe complications nor scar aggravation was observed.
Conclusion: The combination of PDL and fractional CO laser showed good efficacy in the treatment of pediatric patients with burn scars with no severe complications and can be recommended in clinical application.

Objective: We sought to compare the safety and efficacy of combining fractional 2940-nm Erbium:YAG (Er:YAG) laser with autologous platelet-rich plasma (PRP) versus its combination with low-level laser therapy (LLLT) for enhancing the outcome of postsurgical and post-traumatic scars.
Methods: Fourty-five individuals with post-surgical or post-traumatic scars were randomly divided into three groups: Group A received four fractional Er:YAG laser sessions spaced four weeks apart along with eight sessions of intradermal PRP injections spaced two weeks apart; Group B received four fractional Er:YAG laser sessions spaced four weeks apart along with two sessions of light emitting diode (LED) weekly; and Group C received four fractional Er:YAG laser sessions spaced four weeks apart. Treatment efficacy was evaluated using clinical photographs, Vancouver Scar Scale (VSS), patient satisfaction and histopathology.

Background: The use of non-ablative fractionated lasers for skin rejuvenation has been proven to be effective in improving skin texture, and has become popular due to minimal wounding, significantly shorter recovery times and decreased adverse effects.
Objective: To retrospectively analyze improvement in skin texture in healthy women aged over 18 years with Fitzpatrick skin type II-IV.
Methods: Participants received 3 facial and/or neck treatments with the 1570-nm fractional scanning diode laser at one-month intervals.

Ablative fractional laser-assisted drug delivery has gained attention as a promising method for enhancing dermal drug absorption and improving therapeutic outcomes in dermatological conditions, particularly for hypertrophic and keloid scars. However, despite the growing number of clinical trials and case reports supporting its efficacy, there remains a scarcity of robust evidence on the topical bioavailability and dermato-pharmacokinetics of drugs in human subjects. This study aimed to examine the enhancement of triamcinolone acetonide (TAC) bioavailability following treatment with a fractional Erbium-Doped Yttrium Aluminum Garnet (Er: YAG) laser.
