I’ve been using the COSRX 23% Vitamin C Serum for a few weeks now and wow — the glow is real. My skin looks noticeably brighter, and some old acne scars are finally fading. The combo of Vitamin E + Hyaluronic Acid definitely helps keep it from being too drying, even with such a high vitamin C concentration. But let’s talk texture and scent: it feels a bit oily going on (not heavy, just slick), and the smell? 🥴 Think hot dog water. Not cute — but it fades fast, so I deal with it. I keep it in the fridge, apply it after toner and before moisturizer, and I’ve had no irritation (combo skin here). The bottle is small, but if you’re consistent, it’s worth every drop. Just use it up before it oxidizes. Would I repurchase? Yes, if my skin keeps glowing like this. Just wish it smelled like citrus instead of… whatever that is 😅

This product is amazing got rid of my hyperpigmentation and I have the snail mucin same brand cosrx love their products. Really like this vitamin c I was struggling to find a good one and this is perfect

This Vitamin C has been the best serum I have bought, the packaging is very aesthetic which I love. The texture feels so nice on the skin and immediately gives you a glow.
