Decapeptide-12
Also known as: Decapeptide-12
A synthetic ten-amino-acid cosmetic peptide studied as a topical tyrosinase inhibitor to reduce hyperpigmentation and even skin tone.
Last updated
Mechanism of Action
Decapeptide-12 acts primarily as a competitive inhibitor of tyrosinase, the rate-limiting enzyme in melanin biosynthesis, thereby reducing conversion of tyrosine to DOPA and downstream eumelanin. By lowering melanocyte melanin output it is researched for fading melasma and post-inflammatory hyperpigmentation. As a topical cosmetic peptide it is intended to act locally within the epidermis with negligible systemic absorption.

Contraindications
- Known hypersensitivity to the peptide or formulation excipients
- Application to broken or actively inflamed skin
- Use without adequate photoprotection during pigment treatment
Nonapeptide-1
Nonapeptide-1 is a nine-amino-acid cosmetic peptide that inhibits melanin formation by antagonizing the melanocortin-1 receptor. It is used topically for skin brightening and pigment control.
Melanostatin DM
Melanostatin DM is a topical nonapeptide marketed as a skin-brightening agent that reduces melanin production. It is studied for evening skin tone and lightening hyperpigmentation.
Matrixyl
Matrixyl is a palmitoylated pentapeptide (Pal-KTTKS) used topically to stimulate collagen and extracellular matrix synthesis. It is a widely studied cosmetic anti-wrinkle peptide.
