Serine
What Serine is & what it does
An amino acid that acts as a humectant and part of the skin's natural moisturizing factor, helping keep the surface hydrated and smooth.
What does Serine do in skincare?
Serine is an amino acid that occurs naturally in the skin as part of its moisturizing system. In skincare formulas it is commonly used as a humectant and skin conditioning agent, helping support hydration and a smooth surface. It is often included alongside other amino acids.
Is Serine safe?
Serine is a naturally occurring amino acid and is generally considered safe for use in cosmetics. It is used at low levels and is well tolerated by most skin types. Reactions to it are rare.
Is Serine vegan?
The Serine used in cosmetics is usually produced by fermentation or synthesis, which can make it suitable for vegan products. Because amino acids can in principle be sourced different ways, the safest check is the brand's own vegan statement. The finished product's vegan status also depends on its other ingredients.
