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.

Helps with acne

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.

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

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.

Brilliant. Bought a because I needed to switch from 10% to 15% and couldn't find 15% at local Boots. Very nice texture - stings a little at the beginning but got used to it after a couple of uses. Apparently, this is normal. Lasted me around 6 months (using 2x a day). It's a bit more on a pricy side but I think it's worth it. Will try different products from this brand.

Was itching me. Didn't use

Oooh I like this . Tried after seeing in a national press supplement. (not this brand ) but similar. I am definitely noticing smoother , even skin tone . Only been using for a month but it's working well so far .

Good serum have been using for a while now and have seen a drastic change in scars, very hydrating no stickiness my pigmentation has also reduced to a great extent

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

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.

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.
