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.
Worth using if…
- Rough, flaky texture
- Sensitive skin
- Buffering an active-heavy routine
Safety & watch-outs
- Subtle by design — it supports a formula rather than driving results.
Allantoin in pregnancy: Not on standard avoid lists
Not on standard pregnancy avoid lists.
Fungal acne (): does not feed it
Soothing agent, not a lipid. The fungal-acne yeast feeds on fatty acids roughly C11–C24 and the esters built from them, so what matters in a finished formula is the whole list, not one ingredient.
Check a whole formula for malassezia triggers →Comedogenic rating: 0/5 · non-comedogenic
Non-comedogenic. Ratings come from the published Fulton scale, which was measured on rabbit ears rather than human faces — treat it as a rough signal, not a verdict on a finished formula.

Does allantoin exfoliate?
Mildly — it softens and loosens dead cells rather than dissolving them like an acid.
