What does it do?

L-cystine is a type of amino acid formed by the combination of two cysteine molecules and plays an important role in protein synthesis. It is mainly used in pharmaceuticals to support the health of hair and skin tissues. It stabilizes protein structure and contributes to cell regeneration.

L-cystine acts as a major component of keratin proteins that make up the skin and hair. It has antioxidant effects in the body and promotes the recovery and regeneration of damaged tissues. This helps in maintaining the health of hair and skin.

Approved uses differ by product. Check each product's information for its actual use.

Good to know
