O2 Vitamin C Brighten Defend Serum

O2 Vitamin C Brighten Defend Serum by Element Eight is a skincare product, filed under Skincare. Skincare works on a schedule of weeks rather than days — most formulas need consistent use before there is anything to see. Start with a small amount every other day and build up frequency once your skin has settled. A discounted listing is only a saving if it is the same size and edition as the one beside it. Follow with SPF in the morning: plenty of active ingredients leave skin more sensitive to sunlight than usual. The best deal and the cheapest sticker price are not always the same listing once delivery is counted.
