If you have sensitive skin (I don't) you should really be careful when you start using chemical exfoliators. DON'T start using it everyday right away.

This product will slowly remove dead skin. The day after I apply it, I see some flaky skin here and there and they fall off when I wash my face with water.

Since I  have started using CosRX's AHA there has really been a difference in my skin.

I have less whiteheads, my skin is smoother, and my hyper pigmentation from acne seems to disappear faster.

However, I think it requires patience and consistent use.

You should be careful not to over-exfoliate as well.

I will re-purchase with I finish my current bottle.
