I have acne prone skin as well. I noticed I started to get more breakout with my full face mask. I added a charcoal face mask into my routine 3 times a week. I also started washing my face right before I put my mask on and first thing in the morning. I sweat in my sleep a lot so it felt like the mask was just trapping the oils in at night. I hope this help. Warmly, Brittany (Team Member and Advocate)
