Product details

This two-in-one antioxidant treatment works by two different mechanisms to help improve the appearance of ageing skin both inside and out. Below the surface, a 15% concentration of pure vitamin C neutralises free radicals, defends against environmental damage, and helps prevent signs of premature ageing. On the surface, a 10% concentration of hydroxy acids exfoliates to smooth the skin and create a more youthful appearance. C + AHA incorporates both glycolic and lactic acids to slough off the rough outer layer of the skin, revealing newer, youthful skin under the surface.

  • Reduces the appearance of fine lines and wrinkles, neutralises free radicals, and protects against environmental damage
  • Using Duke-patented vitamin C technology, delivers 15% L-ascorbic acid to the skin —formulated at a precise pH and concentration shown to be effective
  • 10% hydroxy acids provide exfoliation to remove dry, dull surface cells and reveal youthful skin below

How to use

In the morning after cleansing, apply 4-5 drops to a dry face, neck and chest. Can also be used on the backs of the hands

Science & Proof

Formulated according to the Duke Antioxidant Patent, this serum delivers a 15% concentration of L-ascorbic acid that can be effectively absorbed by the skin.

Innovation 1

L-ascorbic acid has a reservoir effect, which means it can’t be washed off or rubbed off for a minimum of 72 hours.
