Nihon Antioxidant Serum

Nihon Antioxidant Serum by IKI Skincare is listed here as a skincare product. Order matters in a routine: thinner, water-based textures go on before richer creams and oils, or the layers underneath never land. 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. Check the period-after-opening symbol on the pack; once opened, a formula is on a shorter clock than the printed expiry. The best deal and the cheapest sticker price are not always the same listing once delivery is counted.
