i need some advice on how to get rid of my ugly dark patches on my face. I always had a clear skin but am now on so many different medications including ritalin and have noticed that my skjin is becoming very dark, dry and not the way it used to be smooth without a blemish and now its changing. my feet are also hard, heels dry and cracks making me feel ugly and i am depressed about the changes that i am going through. please can you give me some advice?
