2025年3月6日 · Understanding Keratin - structure and composition, functions, applications in cosmetics and personal care, medical and biotechnological applications

Keratin (/ ˈkɛrətɪn / [1][2]) is one of a family of structural fibrous proteins also known as scleroproteins. It is the key structural material making up scales, hair, nails, feathers, horns, claws, hooves, and the outer layer of skin in vertebrates. Keratin also protects epithelial cells from damage or stress.

What is keratin? Keratin is a protein that helps form hair, nails and your skin’s outer layer (epidermis). It helps support your skin, heal wounds and keep your nails and hair healthy.
