Speaking of this -- does anyone know what the hell causes that line on the thinskin hairline? It seems like it's far less noticeable on one side of my hairline than the other side... it seems like it should be avoidable.

Phoenix, I know you mentioned using that dermablend cover creme, but it's got mineral oil in it, which apparently can break down glues, so using it on the hairline would probably not be good...
