What is the difference between the Cellex-C vitamin-C serums and the vitamin-C creams?
The serums are the purest form of Vitamin-C and contain high concentrations of L-ascorbic acid (vitamin C) and may be used by any skin-type according to sensitivity: Sensitive Serum: 7% High Potency Serum: 10% Advanced C Serum: 17.5% The creams, while also providing high concentrations of Vitamin-C, contain extra antioxidant ingredients. They tend to be more moisturizing, which is great for dry and mature skin-types, but are not moisturizers. They are considered a treatment and users will still need to wear a moisturizer and an SPF. Skin Firming Cream: 10% Skin Firming Cream Plus: 10% with Lycopene, a powerful antioxidant derived from tomatoes. Advanced C Skin Tightening Cream: 17.5% with antioxidants ergothyoneine and grapeseed extract.
