BUTYL 2-GLYCERYL ASCORBATE.

Valuable / ANTIOXIDANT, HUMECTANT

A next-generation Vitamin C derivative engineered with amphiphilic properties that delivers both water and oil solubility for enhanced skin penetration. Part of the innovative iVC series, this stabilized ascorbate derivative targets multiple skin concerns simultaneously, from pore visibility to sebum regulation. Unlike traditional Vitamin C, it maintains stability across a broad pH range while providing sustained antioxidant protection without the typical browning or irritation.

Summary

antioxidant humectant skin-brightening sebum-regulating anti-acne

Science

Mechanism of Action

Functions as a multi-action Vitamin C complex where the ascorbic acid core delivers antioxidant protection, tyrosinase inhibition for brightening, and collagen synthesis stimulation. The glyceryl component provides humectant properties for moisture retention, while the butyl chain enhances penetration and enables inhibition of surface lipid oxidation. Additionally targets sebaceous activity through 5α-reductase and lipase inhibition, plus antibacterial action against C. acnes.
