L-cystine is a compound formed by two L-cysteine molecules, a sulfur-containing amino acid crucial for keratin production. Keratin is a primary structural protein in hair, nails, and skin, with more than 17% of its composition being cysteine. The smaller size of L-cystine molecules compared to cystine allows for easier assimilation.

Keratin fibres bind together for greater strength thanks to disulphide bridges formed by the sulphur provided by the cysteine molecules.

• Hair: L-cystine enhances hair strength and flexibility, reducing breakage.
• Nails: L-cystine increases the hardness of nail keratin by forming disulphide bridges, which prevent brittleness, cracking, and splitting.
• Skin: Keratin supports the skin barrier, aiding in protection, hydration, and cell renewal through desquamation, making up the epidermis, the skin’s outermost layer.

Rich in plant silica, bamboo shoot extract helps remineralize and fortify hair. It also plays a crucial role in protecting and moisturizing the skin by contributing to the synthesis and structural integrity of collagen and elastin, key proteins in connective tissue.

This formula includes a variety of vitamins and minerals that support the health of hair, nails, and skin. These nutrients are vital for the synthesis and metabolism of amino acids (like cysteine) and proteins (such as collagen), essential components of these tissues.
