🍊 COSRX offers two Vitamin C serums in this series: a 13% and a 23% concentration. I’ve tried both, and while the 23% didn’t work well for my skin, the 13% has completely won me over. It works so much better for me!
🍊 The main ingredients in this serum include 13% Ascorbic Acid (Vitamin C) for brightening and fading dark spots, Vitamin E for enhanced antioxidant benefits, Allantoin to soothe and calm the skin, and Hyaluronic Acid for hydration.
🍊 The texture is lightweight, resembling a light oil but with a noticeable water-based feel, making it incredibly comfortable for oily skin like mine. It doesn’t feel greasy or heavy, which is perfect, especially in hot weather. The hydration level is just right—not too much—so it’s ideal for morning or daytime use.
🍊 The serum has a mild scent typical of pure Vitamin C products, but it’s not overpowering. It absorbs quickly into the skin without leaving any stickiness.
🍊 As for results, I noticed visible improvements within the first week of use. It significantly reduced dullness, brightened my skin, and even made my dark spots less noticeable. My skin now looks much healthier and radiant. Another plus is that the formula is gentle enough to use even when my skin feels irritated.
