"i have had acne for about 7 years now and my doctor recently put me on a combination of to topical creams &#039;clindamycin&#039; &amp; &#039;differrin&#039; &amp; a perscription of benzol perosive fave wash along with an antibiotic &#039;doxycycline&#039;. i suffer from white heads and blackheads more then pimples. i&#039;ve been on the combination of medications for 2 weeks now and i&#039;ve noticed a huge change. my black heads are disappearing and my skin is becoming smooth..only negative thing is its causing bad dry skin and a slight burn to my face so i cut the face wash benzoyl peroxide down to every other day and the burning is going away.i highly recommend this treatment."
