Who it's for: All Skin Types. What it is: Unique de-aging Booster harnesses the full power of pure, fresh Vitamin C at our highest concentration to brighten, even and retexturize skin. What it does: Just like your morning fresh-pressed juice or vitamin helps you stay healthy on the inside, this super-potent Booster was designed as a daily supplement to visibly rejuvenate skin from the outside - and a simple, seamless way to reinvigorate your de-aging routine without changing a thing. Simply mix 2 drops with your moisturizer AM & PM and see: 36% brighter skin with first application, 32% reduction of age spots, and 43% reduction in the look of lines and wrinkles over time. Great to know: Fresh means powerful. Pure Vitamin C naturally degrades when exposed to oxygen, so it's most powerful when fresh. Stay-fresh packaging isolates the pure Vitamin C until activation, maintaining its freshness and full power for maximum results. How to use: 1. Leave cap on. Remove foil. 2. Firmly press inner bulb twice to release Vitamin C powder into the soothing emulsion. 3. Shake 15 seconds, and before each use. 4. Remove cap. 5. Mix 2 drops with your moisturizer AM and PM to power up your regular routine. Avoid eye area. Shake before each use. For full potency, use within 7 days then discard. Note: once activated, Booster retains full power for 7 days but may darken due to normal Vitamin C oxidation. 0.29 oz. Made in USA.
