BENEFITS Our most advanced pure vitamin C serum for instant and visible brightening. This clinically proven serum is powered by 15% L-ascorbic acid, the purest and most active form of vitamin C, to instantly brighten skin while visibly improving uneven tone, texture, fine lines, wrinkles, and loss of firmness.L-ascorbic acid is intentionally combined with ferulic acid and vitamin E to create a highly potent, non-irritating serum that remains gentle enough for twice daily use.

When used consistently, it leaves skin looking smoother, more even, and noticeably more radiant.At a glance:- Helps skin look instantly brighter with L-ascorbic acid (pure vitamin C) - Clinically proven to improve visible signs of aging* - Clinically proven to boost hydration** - Ferulic acid & vitamin E boosts skin’s defenses while stabilizing vitamin C - Lightweight, fast-absorbing serum layers well under makeup - Non-irritating formula is suitable for all skin types*** - Has an optimal pH range of 3.10-3.50*Based on an independent clinical study with 30 subjects after 4 weeks, using expert grading. **Based on an independent clinical study with 31 subjects after 1 week, using instrumental measurement. ***Shown to be non-irritating under normal conditions of use.Behind the science:L-ascorbic acid (also known as pure vitamin C) is vitamin C in its active form, ready to work as soon as it’s absorbed by skin. Because it doesn’t require conversion, it’s considered the most efficient form of vitamin C. The tradeoff? L-ascorbic acid can be unstable and may cause irritation in some formulas. That’s why it’s paired with ferulic acid and vitamin E, which help stabilize the vitamin C. HOW TO USE When To Apply Apply up to twice daily, in the AM and PM, after cleansing and toning/exfoliating.
