Overview

  • Update! This product has now been reformulated with a more advanced form of Vitamin C (Ethyl Ascorbic Acid). The new formula is clear, and even less prone to oxidation due to being anhydrous.

  • Stabilised vitamin C (Ethyl Ascorbic Acid) can help brighten dull skin, reduce the appearance of age spots and hyperpigmentation, and significantly reduce acne bacteria.
  • Ethyl Ascorbic Acid’s lipophilic and hydrophilic properties allow it to be easily absorbed by the skin, making it one of the most stable and efficient forms of ascorbic acid.
  • Free of parabens, silicones, PEGs, SLS, SLES, and mineral oils. Vegan and cruelty-free. Made in the UK.
  • Use on its own or underneath your favourite moisturiser.
