Abstract: studies demonstrate antioxidant, anti-aging, anti-inflammatory, photoprotective, wound-healing, and antimicrobial activities. Animal models show photoprotection and wound-healing effects. These studies highlight the multifunctional dermatological value of coffee-derived materials as ingredients for cosmetic and therapeutic formulations aimed at combating skin aging, inflammation, and barrier dysfunction. Limited human trials (typically small sample sizes and short duration) report modest improvements in skin hydration, elasticity, barrier function, and reductions in erythema, transepidermal water loss, and ultraviolet-induced damage, though methodological limitations constrain interpretation. Observational epidemiological studies report inverse associations between coffee consumption and melanoma/basal cell carcinoma risk, but residual confounding by sun exposure, lifestyle factors, and genetic susceptibility precludes causal inference. Critical translational barriers include insufficient pharmacokinetic characterization, inadequate extract standardization across sources and processing methods, formulation challenges, bioavailability uncertainties, and limited independent validation. While preclinical evidence supports diverse biological activities and suggests multifunctional potential for cosmetic and therapeutic applications, current evidence remains insufficient to recommend coffee-derived products as a primary evidence-based dermatological intervention. Overall, large-scale, independent clinical trials with adequate duration and clinically meaningful endpoints are essential for translating laboratory findings into validated clinical applications.
