[Skin Concerns] How do I get rid of a returning patch of raised skin?

Beauty Tips For Body Care
I think this started with some acne that I picked on my forehead. And yes, I know, you're not supposed to pick, but it can be difficult. Now I have this small patch of skin that's raised above the rest, like a scab. So basically, the skin will grow, it will dry, I will pick it off (if I were being diligent I would use my Konjac sponge, but I usually don't), and then it will grow back, and I'll repeat the whole process. The skin underneath the scab looks a bit different from the rest of my face, but it isn't red or irritated or anything. However, this bit of skin keeps growing back. How do I break the cycle?
