Science
Mechanism of Action
This ingredient is hypothesized to function by delivering both L-ascorbic acid and the pentapeptide synergistically to cutaneous cells. The succinoyl linker, being labile to esterase enzymes, is believed to precisely release these active components upon absorption. Once liberated, these compounds are thought to collectively stimulate collagen biosynthesis, provide robust antioxidant protection, and inhibit melanin synthesis, contributing to comprehensive skin rejuvenation.

Stability
This conjugated form of L-ascorbic acid demonstrates superior aqueous stability compared to pure L-ascorbic acid, which is typically most stable below pH 3.5. SUCCINOYL ASCORBATE PENTAPEPTIDE-6 performs optimally within a slightly acidic pH range of 6.0 to 7.0. Its stability can be compromised by the presence of metal ions and excessively high pH environments.

Safety
Safety Profile
While the Cosmetic Ingredient Review (CIR) Expert Panel has deemed L-ascorbic acid, its salts, and various peptides safe for cosmetic applications, SUCCINOYL ASCORBATE PENTAPEPTIDE-6 itself has not undergone a specific safety review by the CIR or the Scientific Committee on Consumer Safety (SCCS). The FDA has not issued a specific cosmetic status for this compound, although L-ascorbic acid and its salts are recognized as GRAS for certain food-related uses.
