This article contains the late-breaking abstracts from the 39th Annual Conference of the American Society for Laser Medicine and Surgery and does not present new research results.

In this study, researchers used a 3D printing technique to spatially pattern human dermal papilla cell spheroids in a collagen matrix, enhancing skin and hair regeneration in a mouse model, with notable upregulation of key genes for hair follicle formation compared to traditional cell cultures.

This review summarizes late-breaking abstracts from the American Society for Laser Medicine and Surgery, 2018, and reports no new clinical findings.

In this review, the authors report that fractional resurfacing can be a safe and effective technique for treating scars and promoting photorejuvenation in Asian skin, though it requires cautious use to minimize risks like post-inflammatory hyperpigmentation and rebound melasma.

This study found that micro-needling with cosmeceuticals or platelet-rich plasma significantly improved wrinkles, skin laxity, scar softening, and hair growth over 12 months, with minimal side effects, and that the best results occur with pigment and platelet massaging between 5 to 30 minutes post-treatment.

This study demonstrated that customized microneedle arrays can precisely induce targeted hair regeneration and improve hair quality in mice, potentially offering a personalized treatment approach for hair loss.

In this laboratory study with rats, treatment with finasteride reduced dihydrotestosterone levels and fertility parameters, with a 30-day recovery period proving insufficient to fully restore sperm function and fertility.

This study found that non-ablative fractional erbium glass laser treatment affected gene regulation in human skin models by downregulating MMP and interleukin expression, suggesting potential roles in dermal remodeling and anti-inflammatory effects.

This study used a novel fluorescent tagging method in mice to observe collagen IV dynamics during hair follicle development, revealing that alterations in basement membrane turnover can influence epithelial progenitor cell behavior and organ morphology by affecting cell proliferation and movement.

This review discusses various techniques for evaluating hair shedding and alopecia but reports no new clinical results. The authors emphasize the value of specific clinical and instrumental methods in assessing hair growth.

This review found that adipose-derived stem cells and stromal vascular fraction have robust clinical benefits in aesthetic surgery, particularly in facial rejuvenation, scar treatment, and volumetric restoration, with favorable safety profiles.
