Vitamin C Brightening Day Serum

This skincare product is Vitamin C Brightening Day Serum by Olivanna. Active ingredients can be effective and irritating at the same time, which is why the usual advice is to introduce one at a time. 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. 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.
