hi, i am 25 years old female and my problem is that i hav some nail scars on my face which is not so deep but visible... its very light and may be about 3 or four as tiny as a pea or may be small than that but i hate it coz its on my cheek. I just want to get rid of it... it would be great if u can tell me what tratement do i need, what it is called and how much does it cost approximately?
