The C15 Super Booster is a concentrated, light-as-water liquid treatment product designed to supercharge your Paula's Choice serum, or it may be used alone. This serum combines a blend of 15% stabilised Vitamin C (L-Ascorbic Acid), antioxidant Vitamin E, Ferulic Acid, and peptides to repair visible signs of ageing and stimulate collagen production for smoother, brighter and firmer looking skin.

Apply once or twice daily after cleansing and toning. Dispense 2–3 drops and add to your favourite Paula's Choice serum, or use alone and follow with moisturiser where needed.
