Anti-Oxidant Vitamin Serum
- 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
- 97% improvement in fine lines | 94% radiance | 91% firmness — independent 12-week clinical study, 33 patients ages 40-65
I formulated this serum because I operate on skin every day. I see collagen architecture under magnification. I know what tissue needs to regenerate — and what it doesn't need. THD-Ascorbate was chosen because it reaches the dermis where the science actually happens. Every ingredient in this formula earns its place. No fillers. No marketing doses. Just what your skin needs at the cellular level. — Dr. Michele Koo, MD, FACS
