"i have been on and of solodyn and it works awesome every time! i am 43 years old and started breaking out around my mouth. i was convinced it was adult acne. i never had acne in my younger years so i figured now it was my turn. i went to my dermatologist and he prescribed solodyn. i noticed results as early as one week. i do get very dizzy and tired so i take it a couple of hours, before bed. it is very expensive so make sure you get the discount card from your dermatologist."
