Red light therapy (RLT) is a non-invasive modality that uses visible red wavelengths (approximately 620–700 nm) to modulate cellular activity. By stimulating mitochondrial cytochrome c oxidase, RLT increases adenosine triphosphate production, regulates reactive oxygen species, and activates downstream pathways involved in inflammation control, tissue repair, and collagen synthesis. RLT has rapidly expanded into cosmetic dermatology and consumer wellness markets with widespread direct-to-consumer marketing. This review synthesizes current evidence on the mechanisms and cosmetic applications with particular attention to discrepancies between peer-reviewed data and commercial claims.

Delayed complications associated with hyaluronic acid (HA) fillers are a concern in aesthetic medicine. However, clinical strategies for mitigation remain inconsistent, and guidelines often make recommendations that may lack the support of robust evidence. To address this gap, a multidisciplinary expert safety council convened to develop evidence-based recommendations aimed at reducing the delayed complication risk of soft-tissue augmentation with fillers, noting which recommendations are uncertain due to lack of evidence.

Topical carboxytherapy, a transcutaneous carbon dioxide (CO2) delivery system, may support skin repair and regeneration, yet its role as an adjunct to fractional laser treatment remains underexplored.

Dermatoporosis is a condition of fragile, aging skin that manifests as altered pH, wrinkles, laxity, easy bruising, and hyperpigmentation. This study evaluated efficacy, safety, and subject perception after the use of a novel cream, GC (Galderma Laboratories, LP, Fort Worth, TX), on subjects with mature, aging skin.
