Description
Palmitoyl tripeptide-8 is a multifunctional active ingredient that helps reduce irritation due to UV light, immune responses, and unconscious stress in and outside the body. Palmitoyl tripeptide-5 can down-regulate the mRNA levels of microphthalmia-associated transcription factor (MITF) and tyrosinase by inhibiting tyrosinase activity, thus inhibiting the production of melanin in melanocytes. Palmitoyl tripeptide-8 is a signaling cosmetic peptide that promotes collagen synthesis (types I, II and IV) and extracellular matrix protein production by increasing stromal cell activity, making skin look younger and more resilient
