What is the best Vitamin C cream?
This is a trick ………… because the vitamin C creams are not a great use of your money. The serums and gels in 10-20% concentrations have proven to be much more effective as antioxidants in skin (topical not oral). The concentration could be slightly lower and be fine, if the vitamin C is combined with other antioxidants or vit E which helps stabilize the vitamin C. More on skincare products.
