Science
Mechanism of Action
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.

Key findings
- 01 In a 4-week clinical study, topical application significantly reduced pore size and facial shine. It improved oily skin appearance, texture, and facial shine by up to 56%, and reduced pore size by up to 55%.
- 02 Demonstrated significant anti-inflammatory and soothing effects, reducing skin redness, UV-induced inflammation, and irritation by lessening IL-6 and IL-8 pro-inflammatory interleukin production. It also enhances the skin's intrinsic moisture retention capabilities.
