Benefits Of Allantoin For Skin
1. Moisturizing Agent
Allantoin moisturizes the skin to prevent dryness and irritation [4]. It is suitable for sensitive skin too because of its non-irritable nature.

2. Exfoliant
Allantoin helps in shedding dead skin cells. It is a keratolytic agent, meaning it can soften and separate out the cornified (tough) layer of skin. It keeps the skin smooth as the dead skin layer is now shed off.

3. Soothing Property
Allantoin has a calming effect on your skin. It is used as a soothing ingredient in skin care products.

4. Wound Healing Property
Allantoin is known for soothing injured skin and healing wounds [5]. It is often used for skin irritation and rashes.

5. Provides Hydration
Allantoin prevents TEWL (transepidermal water loss) [6] and can retain water in the skin cells. It can make your skin feel plumper and softer again.

6. Cell Proliferation
Allantoin not only helps in shedding of dead skin cells but also in cell turnover. Dull skin in aged people is a result of accumulated dead skin cells. Allantoin helps in cell proliferation [7], thus reducing dullness.
