"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&#039;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&#039;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&#039;s important to exfoliate daily to help the product remove waste from your face."
