"i was using the 0.10% strength which helped greatly with clogged pores, blackheads, small pustules.  however, i also had cystic hormonal acne, which the cream wasn&#039;t effective enough for. i took this in conjunction with spironolactone, but eventually had to take accutane.

downside of this drug: sun-sensitivity, skin peeling, redness 

for the record, it takes weeks to see results, and your acne gets worse before it gets better."
