Benefits of Allantoin
Properties and Uses
Quite a lot of research has been carried out on the compounds found in Allantoin.
Hydrating: Increases the water content of skin.
Desquamating: It encourages natural exfoliation in the stratum corneum, the outer layer of the skin.
Repairing: It is well known for its ability to stimulate cell proliferation, encouraging new tissue growth.
It is known to be extremely wound healing, research has shown that it clears away necrotic tissue, making way for a healthy new tissue.
Healing: An active skin protector it naturally encourages the skins healing process, making it a suitable ingredient for treating minor wounds and irritations.
Relieves dryness: Promotes cellular regeneration, counteracting dryness and repairing an impaired barrier, allantoin encourages sensitive skin to become more resilient.
Protecting: This is one ingredient that really does soften the skin, it also protects chapped, sun damaged skin, studies have shown that it protects against UV induced cell damage.
Soothing: It is considered an excellent anti-irritant, calming and soothing inflamed skin. So its great when used in baby products.
Free Radical Activity: Topical application, helps reduce free radical activity on the skin.
Keratolytic action: In performing its protective and regulatory functions, the outer layer of skin our epidermis, synthesises a very large number of proteins and oils (lipids) that are naturally found in the stratum corneum.
This is referred to as keratinisation, if this is out of balance more keratin than usual is produced and the structure of the barrier function is changed.
Allantoin is clever, in that it actually interacts with the skin’s keratin to thin out an abnormal, thick stratum corneum, this is the reason that allantoin is known for leaving skin feeling smooth.
As little as 0.2% can have the same keratolytic effect as 10-20% urea, an interesting ingredient which you can read all about here.
THE NAKED TRUTH
Allantoin is a core ingredient in many personal care products, this is to do with it’s ability to regenerate cells.
The advantage of allantoin in a formula is that it is very active at low concentrations, up to 0.5% and it is non irritating and non toxic.
One study found an inclusion of just 0.2% demonstrated that over 90% of women with symptoms of redness and cracking, significantly improved.
The fact that allantoin has active keratolytic properties, also means it is the ideal ingredient to combat dandruff, this it does by breaking down large particles in dead skin cells.
