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

I love this product. It has made a huge difference in the look and feel of my skin. It is not oily or greasy and leaves my skin feeling soft and fresh. I am almost done with my second bottle. Only advice I have is that if you have very sensitive skin, apply less product or once every other day since the high concentration could be too drying. Apply sunscreen after use!

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.

I normally use Paula’s Choice Niacinamide for Goch works great but no longer fits my budget. This Niacinamide however, is effective at minimizing pores, budget friendly and makes my skin look amazing and glowy. It does not have a strong fragrance at all and absorbs easily into my skin.

This serum helps me whenever I have a breakout…I really like it.

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!

Few skin care products have done much to improve my complexion, but I really did notice a difference using this on the first bottle. I use it twice a day and top it with a Nutragena Hydro Boost product. No substantive difference in fine lines that I have noticed, but my complexion is much brighter and healty looking. I subscribe to this serum and am on my 6th bottle. It has little to no fragrance. One bottle doesn't last quite a month 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.

Performed as hoped. Reduced pore size and redness on my nose and chin. Will purchase again

I like this product it tightens the pores and you see results pretty fast

Love this!

Llevo años, décadas, buscando productos para mis problemas de piel. Tengo una piel mixta, super sensible, con poros dilatados y por si fuera poco, con tendencia a brotes de acné hormonal. Llevo muchísimo años luchando contra esto, teniendo que probar mil productos, hasta ahora nada me había ayudado, hasta que descubrí la cosmética coreana y su doble limpieza. Es lo único que ha hecho que mi piel mejore. Ahora que estaba consiguiendo una piel mas sana, y mejorar muchísimo los brotes de acné gracias a la doble limpieza, necesitaba cerrar los poros. De nada sirve que mantenga los poros limpios, limpiándolos mil veces, sino se cierran y dejan de producir tanta grasa, por qué el acné vuelve y vuelve y vuelve mientras los poros estén super dilatados y produciendo grasa en exceso. Por eso me centré en buscar algo que los cerrará. Pues después de usar mil productos, de farmacia, de alta cosmética y hasta remedios caseros, el único producto que mis ojos de verdad han visto un resultado positivo, es este suero ❤️ una maravilla. Había probado mil cosas, nada me cerraba los poros y además normalmente me resecaban en exceso y mi piel volvía de producir más exceso de grasa para contraatacar, toda la vida incluso dermatólogos me han recomendado el ácido salicílico y toda la vida, me ido fatal con él, me reseca en exceso y mi piel contraataca produciendo más grasa. Bueno pues gracias a este producto estoy consiguiendo equilibrar el exceso de producción de grasa y me ha cerrado los poros!! No puedo estar más encantada, ya lo he comprado dos veces. La única pega que le pongo es que no dura mucho, lo uso por la mañana y por la noche y la verdad que el bote me dura como dos semanas y medía, y solo uso tres gotas en la mañana y tres en la noche. Lo malo del producto de verdad esque no dura nada y no es especialmente barato, pero como es lo único que me ha funcionado, mientras que pueda, seguiré usandolo.
