Retin-A
"I was on the 0.1 cream started Oct 2014 and ended early March.. I got it for whiteheads and uneven skin tone. After 4 1/2 months whiteheads diminished but left with even more scarring. We are going in to May and my skin hasn't healed. Just ugly red chickenpox on my face. :( Another con about this product I see that my skin texture isn't the same. When I was on it it was smooth but after I finished the tube it's just dull and my pores are huge.  It just looks terrible and so much thinner, and my skin tone is still uneven It's depressing how much this cream has given me the uglies. It aged my skin 20 yrs. I'm only 23 and female btw. I don't know what to do now."
