How it works.
Vitamin C inhibits the enzyme that makes dark spots.
Sun damage and hormonal triggers activate tyrosinase, the enzyme inside melanocytes that produces melanin. Stable 15% L-Ascorbic Acid — paired with ferulic acid and vitamin E for potency — blocks tyrosinase at the source, brightens existing pigment, and neutralizes the free radicals that drive new spots. The result is more even tone, faded sun damage, and visibly luminous skin in 4 to 8 weeks.
The Vitamin C That Actually Works.
Most Vitamin C serums oxidize within weeks and stop working. Dr. Ching's clinical formulation uses 15% L-Ascorbic Acid stabilized with ferulic acid and vitamin E — the same combination used in dermatology offices — at a pH engineered for maximum penetration and potency. Brightens, protects, and evens tone in one daily morning step.
- Clinically Potent 20% Vitamin C Complex – Targets dullness, discoloration, fine lines, and volume loss while shielding skin from oxidative stress.
- Advanced Antioxidant Defense – Bio-compatible antioxidants and Vitamin E work synergistically to neutralize free radicals and protect against environmental damage.
- Rapid-Release Delivery System – Patented technology ensures deep, fast absorption of Vitamin C to visibly brighten and revitalize the skin.
- Microbiome-Friendly Formula – Supports healthy skin flora with a gentle blend of L-Ascorbic Acid, Tetrahexydecyl Ascorbate, and Green Tea Polyphenols.
Visible Results
The actives behind the formula.
15% L-Ascorbic Acid stabilized with ferulic acid, vitamin E, and a deep-penetrating Vitamin C ester — the same combination used in dermatology offices, engineered for maximum potency and shelf-life.
Simple to add to your routine.
Apply 3-4 drops to clean, dry skin in the morning. Follow with moisturizer and SPF 30+ (SPF is essential — Vitamin C boosts its protection). Bottle is light-sensitive — keep cap tightened and away from direct light.
