Context
What Allantoin does
Allantoin loosens the bonds between dead surface cells, which smooths flakiness without the acid sting.
It is widely used as a comforting agent in formulas built around exfoliants, retinoids or UV filters.
Typical use on shelf: 0.1%–0.5%, near the limit of its solubility..
Watch-outs
What to keep in mind
- Subtle by design — it supports a formula rather than driving results.
