Keratin is produced by keratinocytes: cells found in the bottom layer of the epidermis within the hair follicle. Keratin is a protein produced and used by the body and is the main component of skin, nails and hair. It makes them toned and strong. It is therefore a key factor in radiant skin.
The exclusive process used to extract this keratin protects its complete amino acid composition while also making it soluble, thus ensuring that almost all of it – 95%2 – is absorbed by the body.
