C1 Vitamin C Power 1 offers an intelligent, new approach to skincare's gold-standard antioxidant powered by our exclusive TTS³ technology. Specially formulated for skin already acclimatised to vitamin C, this serum combines two forms of vitamin C - one oil-soluble (Lipo-C) and the other water-soluble (Hydro-C) - with EGT Amino Acid. Through powerful synergistic interactions between the two actives, radiance lost to pollution, environmental aggressors, dehydration or stress is restored while the complexion is refined for a more even skin tone and texture. For additional skin brightening and anti-pigmentation support, the serum is infused with Tranexamic Acid and Niacinamide, two versatile ingredients with multiple benefits. Tranexamic Acid helps reduce inflammation and dark spots, while Niacinamide has been proven to even skin tone, strengthen the barrier function and stimulate collagen synthesis. Lightweight and traceless on the skin, C1 can be easily incorporated into any daytime or nighttime routine and used in tandem with other products. | Sarah Chapman Vitamin C POWER 1 Face Serum, 30 ml | Dermstore
