COSRX - SkincareNoob review for BHA Blackhead Power Liquid

Wonderful product for those who have never tried chemical exfoliation-extremely gentle, very mild and unlikely to cause irritation. I expected it to be a slightly viscous liquid, but to my surprise, this was very watery and hydrating. After my first application, I didn't really have very high hopes, I thought I'd have to wait a few weeks to see results, but to my surprise, I noticed that the harder sebaceous filaments(at least I think they were sebaceous filaments?) around my nostrils(where they're most congested) looked a little longer than usual. So I just rubbed them with my finger- and it fell out! It was such a mildly gross but very satisfying experience lol That area of my face has been very smooth and clear ever since, although it hasn't helped with the remaining sebaceous filaments even after two months of regular usage(I use it once a week on my entire face and an extra time just on my T-zone). I also noticed that the very occasional acne I get cleared up almost overnight when I used this, but I should add that acne usually goes away on its own in a day or two on my face, so maybe that was just my face doing its thing. Did not cause any purging. Great value for money, a single bottle is gonna last you a long time.
