Decapeptide-12 200mg Topical Overview
Decapeptide-12 200mg Topical from Peptide Science is the synthetic 10-amino-acid peptide (also known by the trade name Lumixyl), supplied as a topical research formulation for in-vitro melanocyte and pigmentation-pathway research. The compound is one of the most-cited peptide-class research tools in tyrosinase-pathway literature.
Compound Class and Mechanism
Decapeptide-12 is a rationally designed 10-amino-acid synthetic peptide that has been characterised in preclinical research as a competitive inhibitor of the tyrosinase enzyme, the rate-limiting catalyst in the melanin-biosynthesis pathway. The compound has been studied in cultured melanocyte cell-culture models for effects on melanin production downstream of tyrosinase inhibition. The 10-residue sequence is the longest cosmetic-research signal peptide in the catalogue. Browse the broader cosmetic peptide range for related signal peptides studied in dermal-cell research.

Handling and Reconstitution
The topical research formulation is supplied for in-vitro cell-culture and animal-model dermatology work, not as a finished cosmetic product. The working concentration used in any given research protocol is set by the principal investigator. Aliquoting reconstituted stock for single-use storage is the standard handling practice for short signal peptides where repeated freeze-thaw cycles can affect activity.
Quality and Shipping
Each batch passes HPLC at greater than 99 percent purity, with mass-spectrometry identity confirmation. A Certificate of Analysis accompanies every order. Material is prepared in a US laboratory under ISO 9001:2015-aligned quality systems and dispatched in insulated, light-protected packaging via overnight or two-day courier.
