COSRX Niacinamide 15% Face Serum, Minimizing Pores & Sebums, Blemish Treatments for Discoloration, Dark Spots, Enlarged Pores, Anti-aging, 0.67 fl.oz / 20 ml, Animal Testing-Free

Cosrx serum I must say, is hands down the best facial serum I’ve ever used. From the first application, I noticed how smooth and refreshing it felt on my skin. It absorbs quickly, leaves no sticky residue, and gives my face such a healthy, radiant glow. Honestly, I wish I could buy it in dozens — like a pack of twelve — just to make sure I never run out. That’s how much I love it. If you're looking for a serum that truly delivers, this is the one.

My skin looks plump and smooth ! I bleach my skin so needed to improve the thickness of my skin . This products is amazing ! People are beginning to notice !!! Why ? Because the quality of my skin has really improved! Wow …….. like the glow is giving !!! The shine is dewy … the thickness is incredible. I’ve been using it for some months now but when I started, the change was noticed within days. I use it twice a day so it doesn’t last for more than 10-14 days which is annoying , I love love love how my skin feels and how it looks - I love it

It worked and my skin has absolutely improved a lot!Would highly recommend!

Helped improve my skin texture over 3-4 months of usage. Go easy, a tiny drop is good enough for one cheek. Spreads easily. Also I don’t use it every night, it can make your skin slightly dry. Put a layer of moisturiser on top. This product has helped to clear my pores and minimised their appearance. I have oily T-zone.

Great product

Not for me

I am using since 3 months this is my 2nd bottle . Initially 1st week i used and felt no effects but after 15 days trying it was game changer for me . My pimple marks started lighter and my face shine came again after my pregnancy. My skin looks my into like 20’s girl ❤️❤️😍 . Highly recommended.

Face looks hydrated

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

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!

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.
