I'm 52 and I've been on blood pressure medication with the side effect of discoloration of the skin. Recently I was taken off of the meds. but I've noticed that I have a large amount of discoloration in my forehead. My friends and family are constantly asking me why I have the blotches. They are getting more and more noticeable as time past. What can I possible use to even my skin tone again, if its possible?
