"i was prescribed this after being diagnosed at age 29 with severe acne vulgaris. this medication gave me no negative side effects that i noticed and cleared my acne up within 1 week. i was prescribed the once a day dosage which is great. i took a break once for a few days and the acne came back. i dashed to my medicine and got back into my normal routine. acne went away! its a great medication if used properly. helped me become more confident as an adult suffering from acne."
