Description
A gentle daily brightening serum formulated with 13% vitamin C (ascorbic acid), effective enough to visibly fade dark spots, blemishes, and hyperpigmentation, yet gentle enough for sensitive skin types new to vitamin C. Sodium hyaluronate and allantoin keep skin hydrated and calm throughout. A great entry point into vitamin C before graduating to higher concentrations. Always pair with SPF during the day.
Ingredients
Good to know

Three questions we hear
Morning or evening?
Morning is ideal, under your sunscreen.
Can I use it with niacinamide?
Yes. If your skin feels sensitive, use them at different times of day.
Does it change colour?
Vitamin C can darken as it oxidises. Keep it cool and closed, and use it within a few months of opening.
