2 years ago I was diagnosed with psoriasis, I had small scaly patches all over my body. My doctor sent me to a dermatologist where I was given 2 different medications to help clear it up. Eventually all of the scaly spots disappeared but I was left with some small white patches where some of the spots had been. And now some of these areas do not tan like the rest of my body. I was just wondering if the scaly patches will ever return and what kind of things can I do to prevent them from coming back.
