you can use mederma scar cream and over time it they will fade or if you want a asap treatment try using a bit of coverup or foundation. Good luck and you should be proud that you have stopped :)
There are some very thick makeup for the body called camuflage. They cover almost everything. This is what we makeup artists use on stage to cover blemishes and scars on the body. Good Luck! R.
You can't really hide them, you could try covering them with some powder, or fake tan, i doubt anyone would ask anyway!
I have a scar on my face from an accident when I was 3 years old and I apply vitamin E oil on it directly daily and it has helped my scar fade! Hope that helps
nylons should work if they're dark.
Maybe some matching thigh high socks? I'm not sure if that would look good with a dress though.
