Beyond Circadian Rhythm: Melatonin as a Bio-Regulatory Molecule in Skin and Hair Aesthetics
Abstract: Melatonin has long been known for its function in circadian rhythm regulation, but new dermatological studies emphasize its significance as a multifunctional molecule in skin protection and hair biology. Melatonin protects the skin from UV radiation, oxidative stress, and inflammation by acting as a potent antioxidant, radioprotective agent, and mitochondrial stabilizer, according to scientific research. As a component of a "melatoninergic antioxidant system", topical melatonin improves DNA repair, lowers oxidative damage, and regulates inflammatory reactions. Melatonin also affects the cycling of hair follicles and may encourage the prolonging of the anagen phase, which supports hair renewal. In addition to highlighting melatonin's potential therapeutic uses in dermatology and cosmetology, this research examines the biological roles of melatonin in skin defense and hair repair.
