A daily vitamin C boost for brighter, better-protected skin
ISDIN Isdinceutics Flavo-C Serum is a vitamin C serum for all skin types showing the first signs of ageing and dullness. It pairs 8% ascorbic acid with ginkgo biloba extract, two antioxidants that help protect the skin from free radicals linked to UV exposure and pollution. Lactic acid adds gentle hydration and smoothing, for skin that looks brighter, firmer and more even over time.
The texture
A fluid, lightweight serum that you warm between the palms before pressing into the skin. It absorbs quickly and leaves a slightly silky finish that sits well under moisturiser and sunscreen.
Who it suits
- Dull, tired-looking skin
- First fine lines and loss of firmness
- City dwellers exposed to pollution and daily sun
- All skin types, including combination skin
Worth knowing before you buy: Pure vitamin C can tingle on sensitive skin, and the serum is fragrance-free. Keep it away from heat and light, and use it within six months of opening. It works best under a daily sunscreen, not instead of one.
How long a bottle lasts
At 5 drops once a day, the 15ml bottle lasts about two months. Used morning and evening, count on about one month.
