Protein
Protein in beauty products refers to ingredients like hydrolysed wheat, soy or silk proteins that help strengthen and protect skin and hair. These are commonly found in moisturisers, hair conditioners and masks. They work by forming a light film that improves softness and resilience.
How it works in skincare
In cosmetics and skincare, proteins are typically used in their hydrolysed form so they can be easily absorbed or form a protective layer on the surface. They bind well to keratin in hair and the natural moisturising factors in skin, helping to reinforce the structure, reduce moisture loss and improve overall appearance and feel.

Proteins used in UK beauty products are usually derived from natural sources such as wheat, soy, rice, silk or collagen. These are broken down into smaller peptides or amino acids for better performance in formulations.
