What is Allantoin?
Allantoin is a soothing, skin-conditioning ingredient found naturally in the comfrey plant and produced synthetically for skincare use. The synthetic version is identical to the natural form and is preferred for its purity and consistency.
It is widely used in sensitive, baby, and post-procedure skincare for its gentle, calming, and skin-softening properties.
What does Allantoin do for the skin?
- Calms visible irritation and reduces redness
- Softens skin and improves overall comfort
- Gently smooths rough or flaky texture
- Helps skin retain moisture and feel less tight
- Encourages a healthy, comfortable barrier
How does Allantoin work?
Allantoin works as a skin protectant and conditioner — it soothes visibly irritated skin, helps slough away dead surface cells very gently, and improves skin softness and flexibility.
Its mild keratolytic action makes rough patches feel smoother without the irritation that stronger exfoliants can cause.
What concentration of Allantoin is most effective?
Allantoin is typically used at 0.1–2% in skincare. Most well-formulated products fall between 0.5–1%. Higher concentrations are not necessarily more effective and can affect product stability.
How do you use Allantoin in a routine?
Allantoin works in both AM and PM routines and is suitable for daily use. It is found in serums, moisturisers, toners, masks, and recovery products.
Apply after cleansing and before heavier moisturisers. It layers easily with virtually every other active and is especially useful in routines that include retinoids or acids.
