PYRIDOXINE CYCLIC PHOSPHATE.

Valuable CAS 36944-85-1 / HAIR CONDITIONING, SKIN CONDITIONING

Pyridoxine Cyclic Phosphate is a stable, advanced derivative of Vitamin B6 (Pyridoxine), engineered for enhanced skin penetration and efficacy. It precisely targets common skin concerns such as excess sebum production, enlarged pores, and inflammatory responses, leading to comprehensive improvements in skin appearance and texture.

Science

Applied topically, Pyridoxine Cyclic Phosphate efficiently permeates the skin's deeper layers, where it is hydrolyzed by endogenous enzymes into its active form, Pyridoxine. Its primary mechanism involves inhibiting the 5α-reductase enzyme, which consequently reduces dihydrotestosterone (DHT) quantities and significantly lessens sebum production. Furthermore, it modulates the skin's inflammatory cascade by reducing the production of pro-inflammatory interleukins IL-6 and IL-8 by keratocytes, thereby imparting significant anti-inflammatory and soothing effects.
