Our take
Is Serine a Good Ingredient?
Great, because it's an endogenous component of skin's own natural moisturizing factor, which gives it dependable performance, broad compatibility, and a very low irritation risk. That combination of proven mechanism and consistent, low-risk performance is what pushes it past Good.
What it does
Skin Benefits
Replenishes elements of the skin's natural moisturizing factor for a plumper, more elastic feel, and helps reduce the sensation of tightness from dehydration.
Where you'll find it
Uses in Skincare & Cosmetics
Common in moisturizers, toners, and essences to boost everyday hydration without heaviness.
Before you use it
Safety
Low likelihood of irritation or sensitization at typical cosmetic levels. Suitable for most skin types, including sensitive.
