acne
"My skin is sensitive and combination/oily. I have never had horrible or cystic acne, just a few pimples on my forehead all the time. About a month ago, the acne spread to all over my forehead. I knew the problem wasn't my diet or a product because I tried eliminating these things. My dermatologist prescribed me 0.1% differin gel a few weeks ago. There was no difference the first two days but on the third day, I had no new pimples and it's been that way since! I did experience slightly drier skin than usual, but no redness or flaking. I believe the key is to use as little product as possible and moisturize as soon as the product sinks into the skin. Also, it's important to exfoliate daily to help the product remove waste from your face."
