acne
"I am 43.  I've had acne since I was 12, and was very self conscious- especially at my age...I mean, how crappy is acne in your 40's and wrinkles? Ugh. I started taking tretinoin .05%.  I had terrible peeling and dryness for a few months, but I noticed my face starting to get clearer.  Was the drying and peeling worth it- to have dull skin is not cool.  So.....I used an exfoiliating fash wash each morning and once a week used one of those face scrubby things in the shower. Also, I put on a moisturizer with SPF 30- that's important because this stuff will make you burn in the sun! That all worked for me! At around the 6 month time, there was no more acne- only a few zits around the time of my period- AND I get complements on my youthful skin!"
