A gentler vitamin C serum for sensitive skin that still wants daily antioxidant protection
SkinCeuticals Serum 10 AOX+ is a daytime antioxidant serum for sensitive skin, including blemish-prone or easily irritated skin. It combines 10% pure vitamin C (L-ascorbic acid) with 0.2% ferulic acid, a lower dose than SkinCeuticals' classic C E Ferulic, so reactive skin can get the benefits of vitamin C with less risk of stinging. It helps defend the skin against free radicals from UV and pollution, supports collagen and evens out a dull, tired-looking complexion. Panthenol and hyaluronic acid keep the skin comfortable.
The texture
A light, watery serum dispensed with a dropper. It absorbs within a minute and leaves a slightly tacky finish that disappears under moisturiser. Like all pure vitamin C serums it can darken slowly with air and light, so keep the cap closed.
Who it suits
- Sensitive skin that finds stronger vitamin C serums too harsh
- Skin with blemishes that still wants antioxidant care
- Dull or uneven skin showing the first signs of ageing
- Anyone building a morning routine of vitamin C plus sunscreen
Worth knowing before you buy: L-ascorbic acid is acidic, so a light tingle is normal the first few days. It is fragrance-free but contains propylene glycol and ethoxydiglycol. Always follow with a broad-spectrum sunscreen, for example SkinCeuticals Sheer Mineral UV Defense SPF50.
How long one bottle lasts
At 4 to 5 drops each morning, the 30ml bottle lasts about 3 months, which also matches the window in which vitamin C stays at its best once opened.
