Understanding Vitamin C Derivatives

Despite traditional Vitamin C's (aka Ascorbic Acid) notorious instability in cosmetic formulations, derivatives like Tetrahexyldecyl Ascorbate and 3-O-Ethyl-L-Ascorbic Acid rise above to deliver maximum results without the shortened shelf life or oxidative risks. These oil-soluble derivatives don't just boast enhanced stability to preserve their efficacy, their superior skin penetration capabilities optimize the absorption and delivery of vitamin C's high-performance benefits like brightening, antioxidant defense, and the stimulation of collagen synthesis while remaining gentle enough for sensitive skin types.
