Keratin is a protein that is naturally found in hair, nails, and the outer layer of skin. It is often used in haircare and skincare products due to its strengthening and protective properties. In skincare products, keratin is typically derived from animal sources, such as sheep's wool or chicken feathers.

• Strengthens Skin Barrier: Keratin helps to strengthen the skin barrier by forming a protective layer that prevents moisture loss and protects against external aggressors such as pollution and UV radiation.

• Promotes Skin Regeneration: Keratin can stimulate skin cell regeneration, helping to improve the overall texture and appearance of the skin.

• Improves Skin Elasticity: Keratin plays a role in maintaining skin elasticity by helping to keep skin cells tightly packed together. This can help to reduce the appearance of fine lines and wrinkles.

• Repairs Damaged Skin: Keratin has the ability to repair damaged skin by promoting the growth of new skin cells and restoring the skin's natural protective barrier.

• Conditions Hair and Nails: Keratin is also beneficial for hair and nails, as it helps to strengthen and condition these structures, promoting healthy growth and preventing breakage.

Overall, keratin is a versatile ingredient that offers a range of benefits for both skin and hair. Its ability to strengthen and protect the skin barrier, promote skin cell regeneration, and improve skin elasticity make it a valuable addition to many skincare formulations.
