Alanine
Alanine is a gentle amino acid used in many UK skincare and haircare formulas. It helps keep skin and hair soft, hydrated and healthy-looking while improving how products feel on the skin. You’ll often find it in moisturisers, serums, masks and conditioning treatments.
How it works in skincare
In cosmetics alanine functions as a skin-conditioning agent and humectant. It supports the natural moisturising factor within the skin, helping to bind water and maintain softness and suppleness. Its small molecular size also allows it to act as a buffering agent, helping to stabilise the pH of formulations so they remain gentle and effective on the skin.

Where it comes from
Alanine is a naturally occurring amino acid that can be derived from plant sources such as wheat, corn or soy through fermentation. In cosmetic grades it is often produced biotechnologically for purity and consistency.
