Questions about allantoin
What is allantoin?
Allantoin is a small molecule first identified in comfrey root and now produced in pure, cosmetic-grade crystalline form. It has been used for decades as a skin protectant and softening agent, and is considered one of the gentlest, most reliable ingredients in skincare.
What does allantoin do for skin?
Three quiet jobs: it helps soothe the feel of irritation, encourages the natural shedding of dull surface cells for a smoother look, and helps skin retain moisture. Together these leave skin feeling calmer and softer, and looking fresher and more even.
Is allantoin good for sensitive skin?
It is practically the definition of a sensitive-skin ingredient — so well tolerated it appears in baby care. It is effective at low concentrations and often included specifically to buffer stronger actives, keeping a formula comfortable for reactive skin.
Is allantoin natural or synthetic?
Both exist. It occurs naturally in comfrey root and several other plants; the allantoin used in modern cosmetics is typically nature-identical, produced to high purity for consistency and safety. Chemically the two are the same gentle molecule.
