Description

C20 Vitamin C Serum

Potent 20% L-Ascorbic Acid Serum

C20 is a potent, waterless vitamin C serum designed for patients who want more from their antioxidant step. Its anhydrous formula helps optimize product stability while delivering 20% L-Ascorbic Acid in a high-performance system built to support brighter tone, stronger antioxidant defense, and a more youthful-looking complexion.

What sets C20 apart is the water-free format itself. By removing water from the equation, the formula supports a more stable vitamin C story while helping preserve the strength of its antioxidant positioning over time. Ferulic Acid and Vitamin E reinforce that system, creating a more advanced daily defense step for skin affected by dullness, uneven tone, discoloration, and visible signs of aging.

For patients and practices alike, C20 offers a more serious vitamin C option — one designed to brighten, protect, and support healthier-looking skin with a cleaner, more concentrated delivery story. The result is skin that looks fresher, more even, more radiant, and better supported against daily environmental stress.

Why it’s different

Waterless by design. More stable by intent. More powerful in story.

Many vitamin C formulas face the same challenge: keeping L-Ascorbic Acid in an environment that supports performance over time. C20 addresses that directly with an anhydrous, water-free system designed to optimize product stability and strengthen the formula’s antioxidant efficacy story.

That waterless structure also gives the serum a more concentrated, active-first feel on the skin. Combined with Ferulic Acid and Vitamin E, it creates a more complete antioxidant network—one designed to help skin look brighter, clearer, and more youthful while standing up better to everyday oxidative stress.
