Dr Koo Anti-Oxidant Vitamin Serum | THD Vitamin C
- THD-Ascorbate — a lipid-soluble Vitamin C that penetrates the stratum corneum to reach the dermis, where collagen is actually built
- Therapeutic dose, not a marketing dose — every active at the concentration where clinical studies show measurable tissue response
- Supports collagen triple-helix formation — the structural protein that determines skin firmness, elasticity, and wrinkle depth
- Multi-vitamin complex (C, D, E, F, K) with ceramides and marula oil — lipid-soluble delivery vehicles that reinforce the skin barrier
- 94% saw brighter skin | 85% saw more even tone | 91% felt skin more hydrated & dewy — independent 12-week clinical study, 33 patients ages 40-65

I formulated this serum because I operate on skin every day — I've seen under magnification what years of sun damage and oxidative stress do to collagen architecture. THD-Ascorbate is the only form of Vitamin C that crosses the stratum corneum and activates at the fibroblast level, where collagen is actually synthesized. That's not marketing — that's the mechanism that matters.
