What does Allantoin do?#
A gentle moisturizer with allantoin that helps calm the appearance of skin and promotes a smoother, more comfortable-looking complexion.
- Helps soothe the appearance of irritation and redness
- Supports a smoother, softer-looking skin texture
- Promotes a more comfortable, well-conditioned complexion
How it works
Allantoin is a naturally occurring compound known for its skin-conditioning properties. It helps promote a smoother surface texture and softer feel. It also helps soften the look of dry, rough patches and contributes to a calmer, more comfortable-looking appearance.
How to use Allantoin#
- Every day, morning or evening. There is nothing to build up to and no settling-in period to wait out — a full amount is fine from the first day.
- In routine order it goes on last, after anything you apply to bare skin.
- Across the whole face. Smooth it on rather than rubbing it in.
- It shares a routine comfortably with everything else on the shelf, exfoliants and retinoids included, so it never needs an evening of its own.
- Allantoin does not make skin more sensitive to sunlight, so it asks nothing beyond your usual sunscreen.
- Dry or roughened skin is what it suits rather than a reason to hold back, and it has been worn under patches by people with sensitive and allergy-prone skin without any sign of irritation.
- Avoid getting the product directly into your eyes — rinse with water if it happens.
Discontinue use if unexpected discomfort occurs.

How we check this#
Everything on this page traces to the sources listed below — regulators' own publications and published studies. Where the evidence does not answer a question, it is left unanswered.
Some sources below are the official product information for prescription medicines — some contain this ingredient at higher strengths, others are cited for how they interact with it. We use them for their safety and handling detail only. A cosmetic product is not one of those medicines and is not intended to treat any condition.
