I used hydroquinone for 3 months with ZERO results! I saw results in 2 weeks with this peel. I would repurchase, but it may not be necessary because 1/2 oz would last a lifetime if I'm only gonna use it only 3-4 times per year. I only spot treat for now. I just can't do my entire face without looking like a burn victim for 2 weeks. In the back of my mind, I fear that my skin would not heal properly and leave me with skin worse than what I have now... My supervisor asked if I was ok. He probably thought someone hit me in the eye.
I don't think this is worth the money. If I had known that it only had 4 led lights, I would not have even considered it. I still get 1-2 monthly breakouts and clogged pores. However, it does slow down that occasional potentially disasterous eruption, though... I guess it's better than nothing.
