“…Kaewkes and colleagues 24 found significant improvement in skin texture and melanin index with decreased variation in melanin scores using the 1,064-nm fractional laser for 4 treatments with results apparent at up to 6 months of follow-up. Both Park and colleagues 25 and Tang and colleagues used 3 laser treatments with similar wavelength to evaluate striae improvement from baseline. Park and colleagues found that the 1,550-nm Erbium laser significantly improved stretch mark scoring at 12 weeks posttreatment with 3 treatments at 4-week intervals without any resulting PIH.…”

BACKGROUND Fractional nonablative lasers (NAFLs) have demonstrated efficacy and safety for treating dermatologic conditions in patients with darker skin phototypes. Nonablative lasers are preferred in darker skin tones due to lower risk of postinflammatory hyperpigmentation. OBJECTIVE This review aims to identify the ideal laser options and parameters for treating common dermatologic conditions in patients with skin types IV-VI. MATERIALS AND METHODS A comprehensive literature search was conducted on PubMed in May 2023. Of 1,065 articles were identified, and 40 articles met the inclusion criteria. The studies were classified based on design, dermatologic condition, and skin phototype of patients, and assigned levels of evidence according to the Modified Criteria of the Oxford Center of Evidence Based Medicine. RESULTS Strong level 1 evidence supports the treatment of melasma and atrophic scars using NAFL. Moderate level 2 evidence was found for using NAFL in acne vulgaris, striae, and skin rejuvenation; 45% of the studies examined skin types III-IV, 20% III-V, 7.5% II-IV, 5% II-V, 5% IV alone, and 2.5% I-IV. CONCLUSION Further research is needed to determine the optimal treatment modalities and parameters for skin types V and VI. Appropriate device selection and conservative treatment settings are crucial for optimizing outcomes and minimizing adverse events.

Introduction Stretch marks are common atrophic dermal scars with significant physical and psychological effects. Therefore, there is a need for effective cosmetics and procedures for stretch mark treatment. This study aimed to evaluate the efficacy and safety of a novel treatment for stretch marks that is made up of topical formulations containing beta-glucan combined with nanofractional radiofrequency. Methods This randomized, blinded control trial enrolled 64 Chinese women aged 20–45 years at > 6 months after delivery with obvious white or silver abdominal stretch marks. Participants were randomly allocated to group A (blank group), group B (topical product group), group C (product combined with nanofractional radiofrequency), and group D (vehicle combined with nanofractional radiofrequency). The stretch mark width, skin elasticity, skin color, skin thickness, and collagen density were noninvasively measured. Two trained assessors evaluated the severity, color, outline, and relaxation of the striae. Results Group C showed the best treatment efficacy, with no adverse effects observed during the study period. Conclusion Our findings indicate that stretch mark treatment using topical formulations containing beta-glucan, combined with nanofractional radiofrequency plus magnetic nanofractional radiofrequency, is tolerable and effective.

BACKGROUND Striae distensae have notoriously been difficult to treat due to their extensive involvement of nonfacial skin. Microneedling with its lack of thermal injury during microneedling treatment renders it a viable treatment option in darker skin tones and nonfacial regions due to the reduced risk of postinflammatory hyperpigmentation. OBJECTIVE To describe the clinical results and side effects of microneedling in a series of 25 individuals with striae distensae. MATERIALS AND METHODS Twenty-five consecutive adults (SPT I–V) with striae distensae involving the trunk and extremities were treated using a microneedling device. No additional treatments (topical or intralesional) were applied. Two assessors blinded to treatment protocol rated clinical improvement of striae on a 5-point scale. Side effects were monitored and tabulated. RESULTS Patients received 1 to 3 consecutive monthly treatments. All striae improved at least 50% after an average of 1.8 treatments, and 28% of patients demonstrated more than 75% clinical improvement. Striae in thicker skin regions (e.g., buttocks/thighs) showed comparable clinical improvement than those in thinner skin areas (e.g., breasts) and did not require additional treatment sessions. Side effects were limited to transient erythema in all skin phototypes. No infections or dyspigmentation were observed. CONCLUSION The clinical results obtained in this study support the safe and effective treatment of striae distensae with microneedling in light and dark skin tones in various body locations. Standardization of treatment protocols are anticipated with further (ongoing) studies.
