"i&#039;ve never had acne until november of last year. due to large amounts of stress, i broke out all over my forehead and chin. it caused me to get stressed out even more! i went to my doctor to tell her about all the symptoms i&#039;ve been having due to all this stress and she gave me differin for the acne. i&#039;ve only been using it for about 2 weeks now and i&#039;ve definitely noticed a difference! the left side of my forehead is almost completely cleared up! i remember after only 3 night of using this that i woke up and noticed my acne had gotten worse (this is a good thing, i knew it meant that it was pushing the acne up to the surface to get out). i love this!"
