Lysine is an essential amino acid that is involved in the synthesis of collagen, among other things. Due to its antibacterial and anti-inflammatory effects lysine is used in skin care cosmetics to treat acne and to regulate sebum production. Lysine is also valued as an anti-aging active ingredient: it promotes the natural collagen production in the skin and thus provides more resilience and elasticity.

This active ingredient is contained in the amino acid complex.
