Pure vitamin C to firm, brighten and even out skin marked by time
ACM Duolys.CE Intensive Antioxidant Serum is a vitamin C serum for skin showing wrinkles, fine lines, loss of firmness and brown spots. It is built around 15% pure vitamin C (ascorbic acid), kept as a powder in a two-part pack that protects it from air and light until you mix it, so it stays fully active. Natural vitamin E (tocotrienols) boosts the antioxidant effect, while glycerin and squalene keep the skin hydrated. It helps prevent and visibly correct signs of ageing and gives a more even, radiant complexion.
The texture
Once activated, a silky, light serum that spreads easily and absorbs without stickiness, with a soft powdery finish from the silicone elastomers.
Who it suits
- Wrinkles, fine lines and loss of firmness
- Brown spots and uneven skin tone
- Dull, tired skin
- Adults starting or boosting an anti-ageing routine
Worth knowing before you buy: 15% vitamin C can tingle on sensitive skin, and the formula contains fragrance. Use it within the time shown on the pack once activated, and always wear sunscreen in the day.
How long one bottle lasts
Used once a day, the 15ml bottle lasts about four to six weeks, which also matches the use-after-mixing period of fresh vitamin C.
