A 10-day vitamin C treatment for brighter, smoother-looking skin
ISDIN Isdinceutics Flavo-C Forte Serum is a high-strength vitamin C serum for dull, tired skin showing the first signs of photo-ageing, here in a 10-day size. Pure ascorbic acid, the most studied form of vitamin C, is a powerful antioxidant that brightens the complexion, helps even out tone and supports firmer-looking skin. Two forms of hyaluronic acid hydrate, vitamin E adds antioxidant protection, and plant extracts give an instant smoothing effect. It is a simple way to try the formula or give skin a short radiance boost.
The texture
A light, silky serum that spreads easily and absorbs quickly, leaving no sticky film.
Who it suits
- Dull, tired-looking skin
- First wrinkles and uneven tone
- City skin exposed to pollution
- Trying Flavo-C Forte before the full size
Worth knowing before you buy: Pure vitamin C can tingle on very sensitive skin and oxidises once opened, so use it up within the 10 days. The formula contains fragrance. Always pair it with sunscreen in the morning.
How long one bottle lasts
The 5.3ml bottle is sized for about 10 days of daily use, as the name says.
