Our take
Is Melatonin a Good Ingredient?
Emerging studies support antioxidant and barrier benefits in topical formats, with generally good tolerability at cosmetic concentrations, which earns it Good. The evidence is promising but not yet strong across large trials, so it hasn't reached a higher rating.
What it does
Skin Benefits
Helps defend skin against environmental stressors and supports a stronger-feeling barrier, especially in evening routines, though evidence is promising but still maturing for topical use.
Where you'll find it
Uses in Skincare & Cosmetics
Common in night serums, face creams, and eye creams aimed at recovery-focused routines.
Before you use it
Safety
Usually well tolerated, though mild irritation is possible for some users; patch testing is prudent. No widely cited cosmetic regulatory restrictions at typical use levels.
