"this is a miracle in a tube! i had moderate to severe adult acne and would have breakouts on my cheeks, jawline, and chin that would leave dark marks for months. i have oily/sensitive skin. at first, the gel burned a lot and i got a few more pimples, which are side effects of the product. but now after about a month, my skin is adjusting and looks better than it has in years! little to no pimples and dark marks are fading!
my routine:
morning- wash face in lukewarm water with dove exfoliating soap, then apply aveeno clean complexion moisturizer. 
makeup - e.l.f. blemish control primer and bb cream
night- same as morning routine, but add differin gel after washing face with soap, and apply aveeno moisturizer about an hour afterward if needed"
