What it is & what it does
Serine is a skin-identical amino acid and water-binding component used to support skin hydration.
WHAT IT IS: Serine is a skin-relevant amino acid associated with the natural moisturizing factor system and cosmetic conditioning.
HOW IT WORKS / EVIDENCE: Like other skin-identical amino acids, it can help support water balance and surface comfort in a formula. Its role in normal protein biology should not be used to promise that applying it increases dermal collagen or directly reverses age-related changes.
PRACTICAL ROLE: It is best explained as part of a balanced amino-acid and humectant system rather than a stand-alone resurfacing active. The actual finished-product role and supporting evidence govern the claims that can be made.
