COSRX 15% Niacinamide Face Serum, 0.67 fl oz, Pore Minimizer Serum for Face, Even Skin Tone, Korean Skin Care

This is a very good serum. My skin feels almost instantly smoother, softer, and more refined right after applying it. It’s a bit sticky at first, but the stickiness disappears quickly as it absorbs. I’d love to see a 20% version someday, but even at 15% it works amazingly well on my skin. I highly recommend it.

The COSRX Niacinamide 15% Face Serum is an impressive addition to any skincare routine, particularly for those dealing with issues like hyperpigmentation, large pores, and uneven skin tone. Here's a detailed review of its features and performance: **Ingredients and Formula**: The serum boasts a potent concentration of 15% niacinamide, a form of vitamin B3 known for its brightening and anti-inflammatory properties. Additionally, the formula includes other beneficial ingredients such as panthenol (pro-vitamin B5) for hydration, and allantoin to soothe the skin. The serum is free from parabens, sulfates, and artificial fragrances, making it suitable for sensitive skin. **Texture and Application**: The texture of the serum is lightweight and slightly viscous, which allows for easy application without feeling greasy or sticky. It absorbs quickly into the skin, making it convenient for both morning and evening routines. The dropper bottle ensures precise dispensing, minimizing product waste. **Performance**: Users report noticeable improvements in skin texture and tone after consistent use. The high concentration of niacinamide helps to reduce the appearance of dark spots and redness, leading to a more even complexion. Many have also observed a reduction in the size of their pores and an overall smoother skin surface. **Results**: With regular application, typically over a few weeks, the serum effectively diminishes hyperpigmentation and brightens the skin. It also aids in controlling excess sebum production, which can be beneficial for those with oily or acne-prone skin. The hydrating elements in the serum help maintain the skin's moisture barrier, preventing dryness and irritation. **Packaging**: The product comes in a sleek, minimalist bottle with a dropper for easy and hygienic application. The opaque bottle design protects the serum from light exposure, preserving the integrity of the ingredients. **Pros**: - High concentration of niacinamide - Lightweight, non-greasy formula - Noticeable improvements in skin texture and tone - Suitable for sensitive skin - Free from harmful additives **Cons**: - The 15% niacinamide concentration may be too potent for some, potentially causing initial irritation for sensitive skin types. It's advisable to perform a patch test before incorporating it fully into your routine. **Conclusion**: The COSRX Niacinamide 15% Face Serum is a powerful and effective solution for those looking to tackle hyperpigmentation, uneven skin tone, and enlarged pores. Its well-formulated blend of ingredients offers visible results without compromising on skin hydration or comfort. Despite its potency, with proper usage and gradual introduction into a skincare routine, it can become a staple for achieving clearer, brighter skin.

This product I can honestly say has been a remarkable addition to my skincare routine, particularly in addressing my longstanding battle with hyperpigmentation and uneven texture that comes with maturing skin. Its high concentration of niacinamide, known for its skin brightening and texture-improving properties, has genuinely started to transform my complexion. Sense I only apply once per day that’s pretty impressive in my book. From first use, the serum impressed me with its lightweight texture that absorbs seamlessly into the skin, leaving no sticky residue. This feature is particularly important to me, as it allows for easy layering with other products, and sense I apply daily at night it’s an important feature. One of the most noteworthy outcomes I've experienced since incorporating this serum into my regimen has been the visible reduction in dark spots and overall skin discoloration. My hyperpigmentation has gradually become less pronounced, revealing a more even skin tone that I've been striving to achieve for years. Additionally, the serum has effectively minimized the appearance of enlarged pores and provided relief from redness, enhancing my skin's overall clarity and texture. I haven’t noticed a difference in the overall moisture or hydration of my skin but it was never my intention anyway. What sets this product apart for me is not only its efficacy but also its gentle formula. Despite the high concentration of niacinamide, my sensitive skin has tolerated it well without any signs of irritation or dryness. This is a significant advantage, as many potent skincare treatments can be too harsh for delicate skin.. After consistent use, the improvements in my skin are undeniable. While patience is necessary to see full results, this serum has proven to be a powerful ally in reducing hyperpigmentation and enhancing my skin's overall health. I would highly recommend giving it a go if your looking to reverse hyperpigmentation or smooth out pores it’s definitely a product worth incorporating into your routine!

This niacinamide serum is amazing! It’s lightweight, absorbs quickly, and has noticeably reduced the appearance of my pores while keeping my skin smooth and balanced. I also appreciate that it’s gentle, no irritation or dryness, even with daily use. A definite keeper in my skincare routine!

I'm a dark-skinned woman and Oh my god this is the best. I have oily skin and for years every time I tried a new product it would just make my skin oilier after a couple hours of it on my face. This doesn't get oily after time. I only use a hypoallergenic face soap and this serum. And my acne has cleared up. Of course I have good habits like changing my sheets and pillowcases at least once a week, keeping my hair clean and keeping my hands out of my face. Pairing those habits with this little serum while exfoliating once a week has cleared up my skin, minimized blackheads and evened out my skin tone. It's the only thing that works for me.

While searching for products to help fade melasma, I decided to get something with niacinamide instead of vitamin C because of its instability. However, I really wish I would have done a little more research.. After using this for almost a month, I found out that the percentage is much too high for first-time users and/or those with sensitive skin. I might have been fine if I would have slowly introduced it into my routine by using the tiniest amount once or twice a week, but I had no idea that we have to build up a tolerance to new treatment products before we can use them daily. So, my skin is very oily, extremely sensitive, with enlarged pores and melasma. Right off the bat I started using a dropper full of this day and night. 🤦🏻‍♀️ BIG mistake. Not only was my face cherry red all day long, but it dried out my skin in certain areas, AND because I did not bring it close to my eyes or lips, there were noticeably brighter rings around them. It looked like I had a shade of concealer around my eyes and lips that was 5x lighter than my skin tone. A little over a week ago I quit using it entirely, thank goodness I did. Within a couple of days the dry areas and red irritation disappeared, while the bright rings finally returned to my normal skin tone. I regret not taking a picture when it was obvious enough for others to see, you will just have to take my word for it. 😋 Another reason 15% is too strong—maybe unless you are an EXPEIRENCED user—is that many other products we use already have a small percentage of niacinamide added into their serums/moisturizers. For example, CeraVe has it in almost all of their moisturizers and sunscreens. So layering that on top off 15%, could possibly be giving your skin an overdose of up to 16-20% or more. ❗️🚨❗️ At those concentrations it could be very harsh and do the exact opposite of its intended treatment. That being said, if you already have a tolerance to niacinamide and are using other serums/moisturizers that lack it, I would definitely give this a try. 👍 Otherwise, I strongly suggest starting with 5% and working your way up to 10%. Also, be aware of the niacinamide content in other products you use with this! Finally, as for the product itself, because I used it wrong, I don't have much to truly review other than I did notice it helped with excess sebum control. For me, that only benefit was not worth the side effects I encountered. 🙅🏻‍♀️ Also, I noticed a few reviews mention you have to “shake” this before you using it. While that is true, I would not actually shake it as if I am trying to mix a protein drink. Instead, open it and squeeze the dropper to empty it. Close it back up WITHOUT squeezing it again, you want the dropper to be sans product while you do this. Roll it back and forth a few times between your palms like you would a nail polish, turn it around and roll it again. That’s all you have to do. In concluson, because I do love COSRX products, for the extra sebum it got rid of, and the hope that this serum will do its thing when I work up a proper tolerance to it, I rate it 3 stars. They lose two because it is too strong and because they could easily warn consumers how to work up a tolerance for daily use, yet neglect to. 👎 I hope this helps.

I’ve been using the COSRX Niacinamide Serum for almost a year now and it really helps keep my skin clear and smooth. It’s gentle, absorbs quickly, and gives great results without irritation.
