Iron deposits.

Hi, I inherited karitosis polaris from my mom, and when I was younger, I picked at the ingrown hairs and caused big sores. Now I've learned to control my kp almost completely using coconut oils, glycerin and rose water, etc., but where I had picked at on my skin are blotches of brown that a previous doctor had told me were iron deposits. Is there a way that these blotches can be removed or become less noticeable? Its been about 4 years since I've had picked at the spots.
