Rash Marks?!

Rash Marks?

I am a teen with dark coloured skin (male) and I am alergic to grass. When ever I get in contact with grass, I develop a rash (mostly on my face). I went to the doctor, she gave me a cream to applie to my face (she also gave me medicine, so now i can go on grass). I used that cream and the rash has cleared, but it left behind these dark marks (on my forehead and cheeks). The skin near my side burns is normal and it looks very different from the rest of my skin on my face. I am worried the marks will never go away, should I be worried? Also, what can I do to make them go away?

I believe they will go away eventually.But just ask your doctor these questions when you see her again.Don't let people on here guess what to do about it.Your doctor will give you the correct answers.
