The Ordinary's Resveratrol 3% + Ferulic Acid 3% serum is a light, oil-like serum for daily skin protection from the impact of oxidative stress. Using two well-known antioxidants, this formula helps protect your skin from the visual effects of damage caused by environmental stressors, visible signs of aging, and helps it to look brighter and smoother. The bottle is unopened and unused, however, it doesn't look new because it has been sitting in my drawer for a couple of months.
