1.I have dark spots on my upper body. i went to the doctor recently and he suggested demelan cream for pigmentation but the cream highly irritates my skin at the upper chest region.what do i do? 2. I have scars on my face that have been caused by pimples and even look like pimples. (small bumps on my nose). Is there a way of getting rid of them apart from the lazer scar remover??because that is too expensive. Help!? 3. My wounds from falling have caused my skin on the knee to have a weird silky texture and is very dark in color. Some of my other wounds on my leg dont have the silky texture but are dark as well. I want it to turn back to its natural state. what do u prescribe? 4. Lastly. I have 2 dark colored rectangular patches on my skin at the back of the neck on either side. it also has a smooth texture but this is not due to wounds. plz give me ur expertise!!! i really need it. THANKS!
