COSRX - canvas28 review for BHA Blackhead Power Liquid

I have been suffering from blackheads for a long time now and tried various methods to get rid of it. Physical exfoliation didn't give me the expected results. That's when I came across this product. I use this twice per week. I had to wait for more than a month to see any visible results. Other than Blackheads it also helped to mildly exfoliate my skin and clean my pores.
