Is there a new, experimental acne medications routine?

No: A few years ago, a british drug company was investigating a sebum-suppressor that was supposed to be safer than Isotretinoin either for systemic or topical use, but lost interest for reasons that aren't certain -- probably it was a disappointment. A dermatologist can use Isotretinoin and lasers to handle even the most severe acne; this is the 21st century & you should be able to get help.
