"The superhero of skincare ingredients finally captured in a bottle in its pure, fully potent form. This serum has no equal on the market."
– M. Scottson, Pharm. D
This groundbreaking, award-winning serum redefined the standard of how Vitamin C serums should look, feel and perform––which is why it’s earned a cult following from almost every beauty editor in the industry. This water-based serum is bottled in a 100% oxygen-free and light-free environment, capturing Vitamin C in its absolute purest natural form.
Most clients see visible improvements to skin tone and brightness in 14 days. Significant improvements to dark spots and to the thickening of skin's collagen layer can take a full bottle or two when used alone. These improvements are accelerated when paired with the Enzyme-Active Retinol Serum.
Technical specifications:
- Formula pH: 3.46
- Key Ingredient Composition: 10% L-ascorbic acid
- Vehicle: Aqueous solution
- Note on composition and delivery mechanism: Due to the accumulation effects of topical ascorbic acid and the eventual saturation point as documented by Pinnell et al. (ref.), the serum has been calibrated to 10% L-ascorbic acid with a pH of 3.46, which is sufficient to reach the LAA saturation point within 3-4 days of daily application, while also reducing any irritation effects experienced with lower pH and/or higher concentrations of L-ascorbic acid. In an aqueous solution of this nature, additional absorption enhancing ingredients are unnecessary.
- Stabilization technology: Anaerobic manufacturing and bottling using a patented (US Patent # 20240359846A1) process under nitrogen blanket. HPLC assay tests confirmed zero loss of L-ascorbic acid after 60 days of storage at standard ambient conditions (SATP).
- Note on the absence of ferulic acid: Ferulic acid is responsible for the infamous odor experienced in all ferulic acid-based serums as well as the primary irritant. Though it does increase UV protective properties of L-ascorbic acid serums, we believe this task is much more appropriately handled by broad-spectrum sunscreen––making the inclusion of ferulic acid unnecessary and particularly unwarranted given its significant drawbacks in a serum that is stabilized by its packaging technology.
