Allantoin
A well-established comfort and conditioning active
Function in skin biology
Allantoin is a compound found naturally in comfrey root and produced synthetically for cosmetic use (typically from uric acid). It has a long history of use in cosmetic formulation and is evaluated for its association with supporting skin comfort and a soft, conditioned surface feel, with one of the more favourable tolerability profiles among comfort actives.
Why Ambernay evaluates it
Allantoin is evaluated as a supporting comfort ingredient in formulas designed for daily use across skin types, including reactive or sensitised skin contexts, due to its established low-irritation profile.
Where concentration matters
Allantoin is typically formulated at 0.1–2% in cosmetic products. It is effective at low concentrations and is generally used as a supporting ingredient alongside other actives rather than as a standalone formula focus.
What we do not claim
We do not claim that allantoin treats wounds, burns, eczema or other diagnosed skin conditions. Allantoin in a cosmetic formula is evaluated as a comfort and conditioning active — not a pharmaceutical.
Best paired with
Allantoin is broadly compatible with most cosmetic actives and is frequently included in formulas alongside panthenol and centella asiatica for layered comfort support.
Claim caution / regulatory note
Allantoin is a long-established cosmetic ingredient. Claims must remain within cosmetic function: comfort, conditioning, skin feel. Wound-healing or medical repair claims are not permitted in a cosmetic context.
