BHA Blackhead Power Liquid

So I was using the paulas choice bha before I started using the corsx. First of all the corsx definitely lasts much longer than paulas choice, I'm assuming that its because of the pump. I didnt feel as though the corsx had much effect on my combination skin as much as paulas choice did. It did sink into the skin nice and didnt feel sticky. It did not sting. I wanted to love it but after finishing the bottle I did not see a difference.

I've completely switched to Korean skincare for a few months now. I also minimized my skincare routine. Now I use this serum at most twice a week (using it more often is not recommended!) 2/3 weeks later, I see real results, I have much less trouble with clogged pores and blackheads around my nose.
