This product is absolutely amazing! While results may vary, I strongly urge those with blemish-prone skin who've seen my other reviews or are hesitating to make a purchase to give this a try. As someone who's tried various Cosrx products, I can confidently say that everything except their moisturizing cream (which isn't bad, just so-so) has been fantastic for me. The NZ serum's texture is on the richer side due to its high 20% niacinamide content. However, if you apply it in small amounts and layer it gradually, it absorbs well and the stickiness isn't overwhelming - certainly not enough to be bothersome. As someone prone to breakouts, I decided to give this a shot. While individual experiences may differ, this has been the most effective product I've used for calming blemishes among all the niacinamide and zinc-containing skincare I've tried! It's particularly great for those painful, stubborn spots. Despite its potent formula and high concentration of active ingredients, I didn't experience any irritation, even with my super sensitive skin! The only downside is the small amount of product. Even though I tend to make my skincare last, this feels like it runs out too quickly. Due to its rich texture, I recommend applying multiple thin layers rather than one thick layer for the best results. - le*******Dehydrated SkinSebum/BlackheadsInner DrynessEnlarged PoresRecommendedApr 5, 2025
Despite its high niacinamide content, this product causes absolutely no irritation. I was torn between this and COSRX, but since COSRX's 15% formula was reported to cause some irritation, I chose this one and I'm glad I did. It is quite sticky, but I think that's unavoidable given the high concentration. There's nothing I dislike about it. However, due to its stickiness, I'm considering looking for a different niacinamide serum for summer use. - ph****Dehydrated SkinSensitive SkinAcne SkinSebum/BlackheadsInner DrynessWrinkles/ElasticityEnlarged PoresRecommendedNov 12, 2024
This is the thickest niacinamide and zinc serum I've ever used. Unlike typical niacinamide and zinc serums that I'd recommend for oily skin, this one is more suitable for combination or combination dehydrated skin. It's better for winter use rather than summer. Among niacinamide zinc serums, this one pays the most attention to moisturizing ingredients. That's why it worked so well for me in the dead of winter. While high concentrations of niacinamide can sometimes cause irritation, the thick texture of this product makes it the least irritating I've tried. 1. In summer, I found thinner products more suitable. Initially, I bought this serum in summer but set it aside because it felt heavy. I started using it again when winter came, which is why I was dissatisfied at first. In a way, it received a re-evaluation when the right season arrived. 2. Stickiness I accept this due to the high concentration of active ingredients. 
kn********Combination SkinSensitive SkinAcne SkinSebum/BlackheadsEnlarged PoresJan 27, 2024I love that it's packed with high concentrations of niacinamide and zinc. The ingredients are truly top-notch! It feels quite sticky and slippery on the skin. I understand that's probably due to the high concentration of active ingredients, but it takes forever to absorb. Also, I'm not really seeing any noticeable effects. - Hwahae UserCombination SkinAcne SkinBrightening/Dark SpotsRecommendedJan 14, 2024
I absolutely love this product! It's a must-have that should never be discontinued. I plan to keep stocking up and using it. It's incredibly effective for various types of blemishes and dark spots, making it a true all-in-one miracle worker. If I had to find something to criticize, it might be that the zinc ingredient can leave a slight white cast. But honestly, that doesn't bother me at all since zinc is an essential ingredient we definitely need! - ju************Oily SkinBrightening/Dark SpotsSebum/BlackheadsWrinkles/ElasticityRecommendedNov 2, 2023
High concentration yet no irritation. Better than other brands' 10% formulas. Nothing in particular. Among all the cosmetics I've tried, this one offers the best value for money and effectiveness.
