Acetyl Tyrosine

Acetyl Tyrosine is the acetylated derivative of L-tyrosine, a naturally occurring amino acid that serves as a precursor to melanin and key neurotransmitters. The acetylation improves its stability and skin penetration compared to free tyrosine, making it more effective as a skin-conditioning active in cosmetic formulations. Formulators choose it primarily for its role in supporting the skin's natural melanogenesis pathway, making it a popular ingredient in self-tanning and skin-tone-enhancing products, as well as for its amino acid-based conditioning benefits.
