I’ve been using this for several months now and I’m not quite sure if there’s a difference on my blackheads especially on my nose. The only difference I see is that my skin feels soft and hydrated whenever I use this. For the first 3 weeks I’ve been using it for 3 days/week and then gradually increased my usage until I use it daily (every night after I wash my face and apply toner). I was really hoping to see visible results since the reviews for the product are great, however, no visible results for me and my blackheads. Maybe I’m doing something wrong with my routine? Or maybe this product is not for me.

BEST BHA. Hands down.

This changed my skin for the better!! I used to always have breakouts and blackheads, but ever since I started using this, it's kept the blackheads at bay and made my skin appear smoother and brighter! I first used this once a week, and then built it up to twice a week. I'll use this 30 mins before toner, then proceed with my regular skincare routine. This smells really weird though, strangely sour. But I don't mind it because it did some serious magic on my skin. I've been using it since December and I'm only halfway through with my bottle. I'll definitely repurchase this because I feel like my skin can't live without it.

I was skeptical on this at first few uses. Been using this for a little less than a month now. Box shows this should be used once a week at first, then 2-3 times a week until the skin is adjusted. In the reviews here sa beautymnl, very seldom would people mention the frequency of use and how they use this. I was prepping myself to use this as a toner until I got the item and felt its consistency. Para syang serum. So not sure how I can use it with a cotton pad (or none) as a toner. I am used to a very watery consistency for a toner. Nobody here (or atleast from what I read, d ko nabasa lahat ng reviews... andami kaya!) mentioned about the purging stage. So researched online, youtube, etc. Until I found out that since this is bha, it can cause purging. One blog even said purging took her 2 months. Lalabas ang pimp, matutuyo. Then new one comes up again. Until such time this prodict drew out (allegedly) all the impurities under your skin, then that's the time it'll clear up. And I think that's the very same thing that happened to me. I went through that awkward stage na nagdecide ang mga pimples ko na magkumpulan sa certain part ng ilong ko. Para silang grapes dun, nakatambay. Kala ko nga dun na sila titira. There are also some on the cheeks and chin. Paisa isa or dalawa. Ganyan. And true as they say, when you are on that verge of giving the product up, that's the time it'll clear up. I am so relieved hindi na nanganak ang pimples ko. Sana mabaog na sya para d na magpadami pa. Those on my nose are just marks now, healing, clearing up... skin condition's getting a lot better. I am happy I tried this product. Oh btw, this was meant for the blackheads. But I use this all over my face to help clear out the gunk. Every 2-3 days. So far, ok nmn with the blackheads. Cleared up. As evidenced with my nose strips. :) try this, you wont regret it (i hope)

Powerful blackhead killer indeed!

I have been a CosRX loyalist for almost 3 years now and I'm never going back. I am certainly in love with this serum. True to its name, this is my holy grail serum against those pesky blackheads and excess oil. This also helps prevent pimples from forming due to its anti-bacterial properties. Also it's gentle enough to be used everyday. Heck I actually use this twice a day, once in the morning and at night if I'm not going to apply my retinol. Will surely repurchase.

Cleaned my clogged pores and helped small bumps disappear

I've been experimenting with different toners to clear my skin, and this has been the most effective one. It thoroughly removed blackheads and cleaned my pores that I felt some of the gritty grainy stuff come out on the surface in the first couple of days. My skin looked significantly smoother and brighter in a little over a week.
