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.

I have two products from this brand and honestly, I don't understand the hype. It feels nice on the skin, but didn't really see any improvement. It probably exfoliates slightly and that's about it. It's one of those products where you think you're trying, you're taking care of your skin, but if you stop using it, nothing really happens. Can do without it, but did enjoy using it and have finished it. I just don't know if it's all that, you know?

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

Bought this as a more affordable alternative to Paula's Choice 2% BHA. It's not the same and not as good. Won't repurchase. Saying that Paula's Choice is too expensive so I continue to try and find something that delivers the same elsewhere!

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

Good product
