After applying, I can definitely see a gradual reduction in what looks like scars. It stings a bit when applied, but I think that's a good sign. However, the dropper is a little inconvenient to use. 
rk*******Dehydrated SkinSensitive SkinAcne SkinInner DrynessEnlarged PoresRednessRecommendedJun 24, 2025I love how it controls oil! For me, this is all I need in summer. While it feels a bit tight, it keeps oil at bay and manages sebum well. That's actually a good thing! Those with sensitive skin might feel a slight irritation. It's great for small bumps and blemishes. Apply it, let it absorb completely, then follow up with a soothing or hydrating cream. - sj*******Dehydrated SkinSensitive SkinAcne SkinInner DrynessJun 22, 2025
The product itself is lightweight and absorbs well, making it pleasant to use. Unfortunately, it didn't suit me. Usually, I only had small blemishes on my cheeks, but after using this, I suddenly developed inflamed acne all over my face, including my forehead where I never had issues before. - uo******Combination SkinSensitive SkinBrightening/Dark SpotsSebum/BlackheadsDark CirclesInner DrynessWrinkles/ElasticityEnlarged PoresRednessRecommendedJun 22, 2025
The high concentration of niacinamide definitely helps control sebum production effectively. Not recommended for beginners. It's slightly irritating, so I won't be repurchasing. - 07*****Dry SkinSensitive SkinAcne SkinBrightening/Dark SpotsSebum/BlackheadsDark CirclesInner DrynessEnlarged PoresRednessRecommendedJun 21, 2025
It's incredibly hydrating and absorbs instantly! It's truly amazing, and even though I have super sensitive skin, it worked great for me. There's nothing to complain about. It's honestly such an excellent product. This review highlights the product's exceptional hydration and quick absorption. The user, who has sensitive skin, found it suitable and effective. They express strong satisfaction with no negative aspects to report. - ek**********Combination SkinSensitive SkinAcne SkinRecommendedJun 10, 2025
I'm still using it because it's good. I stopped using it in winter, but I'm back to applying it now that summer's here. It seems to keep my skin less oily... It stings.... At first, not knowing any better, I applied two drops to my bare face. The burning sensation scared me so much I had to wash my face again. Since then, I've been mixing 1-2 drops with my toner. It's quite watery, which makes it a bit annoying to apply. Never, ever apply it directly to your bare face.... - cr*******Combination SkinAcne SkinRecommendedJun 9, 2025
My skin feels incredibly smooth. I can really tell the difference compared to other cheaper niacinamide products - this one's noticeably better. There's nothing disappointing about the product itself. However, like with many others, it becomes challenging to use the last bit when the bottle is almost empty. It's hard to get the remaining product out. - si********Dehydrated SkinRecommendedJun 9, 2025
I'm off to buy another one right now! I've gone through 7 bottles already. "It's just straightforward, no frills." I think this is the best niacinamide product out there. The texture has a slight viscosity and feels a bit sticky when applied. While it doesn't completely prevent blemishes, it does seem to help manage them to some extent. When used in skincare before makeup, it seems to reduce oiliness a bit (though some still comes through - we'll tackle that with powder!). I feel like something's missing if I don't use it, so even if I stray occasionally, I always come back to buying and using this product! The glass container might be a bit heavy, but I appreciate that they've put thought into preserving the formula. As a side note, COSRX has great prices and product quality (though I'm not completely satisfied with everything). I've used many of their products and highly recommend them. If you spill it around the opening, it turns white when it dries. But it didn't bother me. It can sting when applied to weakened skin barriers! But I often just applied it and covered it with a repairing cream anyway. When first using, start with a small amount to check for any skin reactions. Due to its high concentration, it may irritate the skin, so when using with retinol or vitamin C, alternate between morning and evening use or gradually acclimate your skin. Our skin is precious, after all! - jd*****Oily SkinAcne SkinRecommendedJun 8, 2025
Helps regulate sebum production. Recommended for oily skin types. There's not much to complain about, but it would be nice if the product came in a larger size. - th*******Dehydrated SkinSensitive SkinInner DrynessWrinkles/ElasticityRecommendedJun 7, 2025
I purchased this product because it contains a high concentration of niacinamide and doesn't have any concerning ingredients. Since I haven't been using it for long, I'm not sure about its effectiveness yet. I suppose it might improve with continued use.
