What is allantoin?

Allantoin is a compound found in the body and it’s also in plants, such as comfrey and chamomile.

In skincare, it’s known for its soothing, moisturising and skin-repairing properties (1).

Why allantoin is important in skincare

Allantoin is used to calm the skin, improve moisture levels and support healing.

It is well tolerated and often included in products for sensitive or stressed skin. It can also be combined with stronger actives to reduce any irritation they might cause (2).

Key benefits:

Calms redness, irritation and sensitivity

Improves skin hydration and reduces dryness

Supports skin repair and regeneration

Softens rough or flaky texture

Helps protect and strengthen the skin barrier

Who should use allantoin?

People with sensitive or reactive skin

Dry, rough or dehydrated skin

Acne-prone skin needing gentle care

Skin with a damaged or weakened barrier

How it works

Allantoin softens keratin in the outer layer of skin, helping dead cells shed more easily. It also acts as a humectant, attracting and retaining water in the skin.

This improves hydration and skin texture (3,4).

Where you’ll find it

Allantoin is found in moisturisers, cleansers, serums and treatments. It is often included in formulas made for sensitive, dry or post-treatment skin.

Safety and tolerance

Allantoin is considered safe and non-irritating. It is commonly used in concentrations up to 2% and is suitable for daily use on most skin types, including sensitive skin (5).

The takeaway

Allantoin is a reliable ingredient for calming and protecting the skin. It supports hydration, repair and barrier health.
