Amino Acid Blend
An amino acid blend is a carefully selected mix of skin-friendly amino acids used in UK skincare and haircare to help support the skin’s natural moisture barrier and improve overall texture.
How it works in skincare
In cosmetics an amino acid blend works by mimicking the natural amino acids found in the skin’s own NMF (natural moisturising factor). These water-binding molecules help reinforce the skin barrier, attract and retain moisture, and support healthy-looking skin and hair without irritation. Formulators often include them in serums, creams, masks and shampoos to boost hydration and softness while improving product feel.

Where it comes from
