I feel a bit the same, sometimes I think what the heck! Other times people ask or if I'm around young kids I don't want to have to evade their curiosity. Hmmm. I suppose I feel people should accept me scars or no scars, but sometimes I don't want to be noticed because of them. Then the skin camouflage helps me feel less conspicuous. It's just a very hard wearing sort of makeup like people would use in films and is blended to match my skin tone. I think it can be used to a certain extent to cover uneven texture too.
I'm glad you feel you can be yourself with them even if the feeling's mixed.
