Vitamin C Serum-in-Oil
£62.00
Most vitamin C products are a problem for anyone with sensitive or reactive skin – ascorbic acid oxidises quickly, can cause irritation, and doesn’t absorb particularly well. What interested me about this serum is that it uses a rare lipid-soluble form of vitamin C instead. That means it bypasses most of the usual downsides: no stinging, no yellowing, stable enough to use in the morning without worrying about photosensitivity. Because it’s oil-based, the active actually reaches the cells rather than sitting on the surface. The endocrine-disruption testing is what brought me to Skin Diligent in the first place, and this is one of their most awarded products.
Why you need this serum:
Vitamin C is the holy grail of antioxidants. But not all vitamin Cs are created the same.
Why this serum is different:
Unlike ascorbic acid and other typical water soluble forms of Vitamin C, which are notorious for being unstable, oxidising and irritant, our VITAMIN C SERUM-IN-OIL is formulated with a rare, lipid form of Vitamin C that is rapidly absorbed to deliver potent antioxidant protection directly at the cellular level, without the common downsides of traditional Vitamin C products.
- Powerful Antioxidant: Features a rare antioxidant system of vitamin C, E and punicic acid for a prolonged antioxidant activity, reducing inflammation, and significantly quenching free radicals produced by sun damage and pollution.
- Brightens and Evens Skin Tone: By regulating melanogenesis, this powerful serum adds radiance to the skin and evens skin tone, attenuates dark spots and softens the skin.
- Optimal Moisturisation: Thanks to its oil formula, it effectively repairs, nourishes and minimises transepidermal water loss.
