O2 Niacinamide Eight Active Serum 1 fl oz

This skincare product is O2 Niacinamide Eight Active Serum 1 fl oz by Element Eight. 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. Discounted listings come and go, and rarely at the same shop twice. Keep the lid closed and the pack out of direct sun — light and air degrade most actives faster than time does. Whoever is cheapest today may not be tomorrow, so it is worth looking again before settling on the best deal.
