Isotretinoin
"My son who has tried almost every available expensive medication from retin-a to antibiotics with not much success finally the dermatologist said we were out of options and Absorbica would be the answer and he was right after 5 months of terribly cracked lips, dry skin and a fair amount of muscle pain the results are beyond amazing while it wasn't a complete no acne ever kind of result it he does get an occasional breakout but it's one or two pimples they are very small and disappear rapidly. Regardless of the expense it was well worth the results."
