C+c Vitamin Splash

C+c Vitamin Splash by Natura Bisse sits in Skincare: a skincare product. Active ingredients can be effective and irritating at the same time, which is why the usual advice is to introduce one at a time. Patch test on the inner arm or along the jaw first, especially if you are already using retinoids, acids or vitamin C. Whether it is discounted this week says more about the shop's stock than about the product. 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.
