Sugar-sweetened beverages and milk are associated with acne in observational studies, but current acne guidelines do not make formal dietary recommendations. Coffee shows mixed observational and Mendelian randomization findings for skin aging and melanoma. For green tea, randomized acne studies show benefit mainly with topical extract, whereas oral effects are limited; matcha remains supported mainly by mechanistic extrapolation. Spearmint tea lowers free testosterone in women with polycystic ovary syndrome, although objective clinical benefit remains unproven. Evidence for chamomile, rooibos, hibiscus, energy drinks, kombucha, and plant-based milk alternatives is limited or indirect. Citrus cocktails and St. John's Wort may cause clinically relevant photosensitization.CONCLUSIONS: Beverage-skin associations vary substantially in evidence strength and causality. Beverage assessment can support individualized counseling as a low-risk adjunct to standard dermatological therapy, while avoiding overstatement of findings derived from observational studies, extracts, or nutraceuticals rather than beverages as consumed.PMID:42805319 | DOI:10.1016/j.clindermatol.2026.09.032
