I've been using Coral Kavi for 3 months. At first, my acne was disappearing, but then I went through a stage where it seemed like all my black heads were purging from my skin. Now, I am getting large painful bumps on my chin again. I have really sensitive skin and acne only in my T-zone, but primarily on my chin. I get large, under-the-skin pimples on my chin, but no where else. They usually come to a head after a few days, but are painful and leave scars. I wash my face once or twice a day, but always before I go to sleep. I don't use any other products besides a moisturizer for sensitive skin. I also wear make-up. Do you think this product is too harsh for my skin? It seems fairly dry and I usually do not do very well with salicylic acid, but I heard such good things about this product I wanted to try it. Your advice would be greatly appreciated!
