COSRX- The Niacinamide 15 Serum

But why use facial oils? Skin tends to overproduce oil when it's been stripped by harsh, drying products like toners and some cleansers, or when it's exposed to harsh or extreme conditions. A facial oil is a quick & effective way of helping to normalise oil production, balancing the look of your skin in the process. An oil is a fantastic and useful addition to any skin care regimen.
