Recommended for

All skin types

Key Ingredients
  • Pure L-ascorbic acid: A vital precursor to neocollagenesis. L-ascorbic acid promotes collagen and elastin production to reduce the appearance of fine lines and regenerate ageing skin. It is a potent antioxidant and offers superior skin brightening.
  • Kojic acid: A natural mushroom-derived antioxidant and antimicrobial agent. Kojic acid reduces the appearance of hyperpigmentation from a cellular level by inhibiting the tyrosinase enzyme, which stimulates melanin production.
