I got this when the website had free shipping - paid approximately $28 AUD total for it, plus 3 free samples. I chose 1% instead of 2% because I was nervous about it being too strong.

I tried it, slight burning sensation but it's not painful, just a little bit irritating, but I think it's expected with a chemical exfoliant. A little bit of skin came off, so don't wear it in the morning if you're going somewhere! Little bit of redness, but it subsiding before waking up in the morning. My skin feels awesome when I use it, and smaller pores @_@
I will write another review when I use it more to see if it clears my acne scars.

I have oily acne prone skin. I dont believe this gave me any new acne.
