Hydrolyzed Silk
Hydrolyzed Silk is a gentle, lightweight ingredient derived from silk fibres that has been broken down into smaller peptides. It is widely used in UK skincare, haircare and makeup to add a silky-smooth feel, boost hydration and improve the overall appearance of skin and hair. Shoppers often look for it in moisturisers, serums, conditioners and primers for its soft-focus finish and conditioning properties.
How it works in skincare
In cosmetics and skincare, Hydrolyzed Silk acts as a film-forming agent and humectant. Once applied, its small peptides create a breathable, invisible layer on the surface of skin or hair that helps lock in moisture while giving a noticeably soft and silky texture. It also enhances product spreadability and leaves a subtle luminous finish, making it a popular addition to lightweight moisturisers, leave-in hair treatments and complexion products.

Where it comes from
Hydrolyzed Silk is produced from the cocoons of the silkworm (Bombyx mori). The natural silk proteins are enzymatically or chemically hydrolysed into smaller, water-soluble peptides for use in cosmetics.
