As an adult who recently turned 60 this story may seem odd but here goes. For the last 10-15 years I've dealt with acne on my forehead and upper face/nose which was very aggravating to say the least. I tried Rodan and Fields and Pro Active with zero results and pretty much gave up a long time ago. Three months ago my wife sent me a video of Dr. Makis talking about Ivermectin paste for acne. I've been using the apple flavored horse paste once a month orally just for the cleanse so I had it in the house.
Dr. Makis suggests using it twice a day but I hate anything on my face overnight so I only applied once in the morning. Within three weeks my face/forehead were acne free and still are. I realize in the grand scheme of things acne isn't a huge deal but it helped me and maybe this will help you or your loved ones in the future. Love this site and and all of you. Be safe and take care.
