I find this AHA/BHA toner is gentle enough for my sensitive skin. I can see improvement on my acne within a week of use (i use it right after washing my face AM/PM). When my skin is extra sensitive, i do feel a slight burning round my nose just above my lips.

Pake toner ini sekitar 3 bulan lebih dan bisa bilang toner ini bagus untuk kamu yang baru mau coba acid toner karena dia kandungan acidnya masih mild. Dikulit ku yang banyak bruntusannya ini gak begitu ngaruh sih tapi nyaman banget dipake dan lembab! Ringkes banget pake ini tu, tinggal spray terus tap-tap dan lanjut aja ke moisturizer. Bisa dipake tiap hari.

I’ve used this product for about 3-4 months now. My skin improves a lot! My face used to be combination (oily at the T-Zone) and now it is normal. Blackheads (or you can call it as sebaceous filaments) on my nose are reduced a lot. I used this as a toner (after cleanser) and leave a 5-10 minutes gap to apply my moisturiser. I recommend this product. My super sensitive skin is not irritated by this product and doesn’t cause any allergy reaction.

What did this product do that your previous products didn't?
This toner is definitely the best toner I have used so far. I do skincare with cleansing (COSRX Low pH), toner with this one, essence (COSRX Snail Essence) and I must say that this toner worked perfectly along with the other two products. Before I used this, I was using Mamonde Rose Water Toner. That toner worked quite well but this COSRX AHA/BHA one definitely did what I was wishing for. It cleared blackheads and prevented whiteheads. It improved the texture of my skin which made me really happy with this one. I also noticed that my skin became more even-toned with consistent use of it (day & night). Unlike others, I did not experience purging. It was nighttime when I first used this and the morning after, my nose was clear of any issue.
