Okay, so I went to the doctor a while back and was going to get a prescription of Veltin (0.025% Tretinoin, 0.1% Clindamycin) I was applying the samples to my face for several months and my face started to clear up. Then I realized the price of the prescription and had to get a cheaper, generic, Tretinoin 0.01% gel. Iv'e been using it for maybe a month and I feel like iv'e been breaking out more than ever. Is this normal?
