C. E.O. 15% Vitamin C Brightening Serum

A concentrated serum powered by 15% THD Ascorbate, a stable, oil-soluble form of Vitamin C that targets dark spots and loss of firmness. The texture is more like a lightweight lotion than a watery serum, making it feel more substantial and less likely to sting than traditional L-ascorbic acid formulas. It’s a solid morning staple for cutting through dullness, especially if you prefer a one-and-done step before moisturizer.
