I took laser treatment for severe acne at the age 15. one year later pimples grew again although not severe. what is 1 final treatment for acne?

Isotretinoin: Isotretinoin (trade name: accutane) is a powerful drug used in the treatment of acne. Four to five months of Accutane treatment usually leads to clearing of acne. It is a potent medication that is very effective for nearly all types of breakouts. Accutane is needed for moderate to severe acne that has failed other treatments. It should be used for a severe, scarring acne.
