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.

L-Ascorbic acid is a key ingredient for fighting ageing and damaging free radicals, promoting collagen production and treating hyperpigmentation. It acts on the melanin pathway by converting O-Dopaquinone back to Dopa. This reduces formation of oxidised melanin and inhibits tyrosinase required for melanin production.
