I have a pimple scab on my forehead, size of a dime, that just doesn t seem to want to fall off. It is very flat, and almost looks wrinkly. It s been on my face for about 2 weeks. I keep moisturizing it as much as I can (neosporin & cerave lotion), so I am wondering whether that is what is making it stay on as long as it has. Should i be keeping it dry instead? I just want to heal the skin underneath. I am desperate, so sick of this thing. The only difference I see from last week that is less red and skin is wrinkly. Please help. Thank you so much!
