Cosmetic Research Analysis
May’s cosmetic research was led by rigorous clinical and mechanistic evidence with practice-facing impact. A multicenter RCT plus multi-omics identified a metabolic RARα–HIC1–PCK1/2 axis through which topical tretinoin prevents hypertrophic scars. Translational hair science converged on NRF2 as a druggable node coordinating ferroptosis and disulfidptosis, while clinical care signals included a double-blind trial in rosacea where a botanical moisturizer outperformed metronidazole and a NEJM negat
