COSRX BHA 4% Blackhead+Niacinamide 2% Exfoliant Toner 3.38 fl.oz / 100ml, Korean Toner, Pore Minimizer for Enlarged Pores, For All Skin Types, Korean Skincare, Not Tested on Animals, Paraben Free

I've been using the COSRX BHA 4% + Niacinamide toner and overall it feels like a solid exfoliating step. It helps with clogged pores and blackheads without being too harsh, though there’s a slight tingling at first. My skin feels a bit smoother and looks less congested over time. It’s easy to use after cleansing with a cotton pad. At £17.01, it feels reasonably priced, especially with Prime delivery and returns. It’s not a miracle product, but a steady addition to a routine.

Takes a few weeks to notice a difference but it’s well worth persevering with. Pores are reduced and it didn’t cause any purging. In the evenings, I wash my face with the COSRX salicylic acid wash, then use the hydrium toner, then niacinamide all over and then this toner where it’s needed (nose and cheeks mainly). It has worked wonders on my skin. The bottle lasts for a few months, so it’s excellent value for money.

Works incredibly well! I usually have oily skin and this product works very well for me. No greasiness, face doesn't look too shiny and dries fairly quickly. I would recommend.

this is so good at removing blackheads and reducing pores. It made my skin so soft and smooth I’m genuinely so impressed

I noticed a difference but it doesn't take the blackheads away fully. I would still recommend. But the packaging is really poor given the price point. It keeps leaking. Thought it was an issue with just one that kept leaking every time I pressed the pump, but the next one I got would always leak if I was carrying it around while travelling for example, even when screwed on tightly, secured with tape and so on. I lost half a bottle of product due to this recently. Reconsidering whether it's worth continuing to buy.

Absolutely love this. My pores are visibly smaller on my nose and tops of my cheeks. It really does get out the gunk! I have dry sensitive skin. Whilst I haven't felt a reaction to it, it can make your skin dry especially around the nose. But I've found the more I use it, I have better toleration of the serum and less flakiness. I use it twice a week on days when I don't use other actives.

Very effective

This product is amazing ive bought this a few times now I have tried others and this is the best, I have a few of corsx products and I have really sensitive skin,but this is amazing for me ,always getting compliments on how great my skin looks not like that Paula choice,which i was recommended,it did nothing but made my skin tingle and made me come out in under skin spots which I never get and like alot of other products ,but this one is best definitely recommend for those with such sensitive skin and if you wanna see results ✌️
