The C15 Super Booster diminishes visible signs of ageing for smoother, brighter, and firmer-feeling skin. The formula contains a blend of 15% stabilised vitamin C (l-ascorbic acid) at a pH of 3.0, potent antioxidants including vitamin E and ferulic acid, and skin-smoothing peptides. Skin is protected from environmental damage and you'll see dramatically younger-looking and more radiant skin day after day.

Apply once or twice daily after cleansing, toning and exfoliating. Dispense 2–3 drops and add to your favourite moisturiser or serum. May also be used alone. For daytime, follow with a broad-spectrum sunscreen rated SPF 30 or greater. May be applied around the under-eye area.
