I personally think that if you can do something to make yourself feel more confident, do it. But I might draw the line at facial tattoos.
People (mostly women) are getting freckle tattoos... so it looks like they have freckles, but they don't have to go out in the sun. (ps--I know some people have freckles with or without sun exposure...I personally only get freckles when I've been in the sun). The tattoos are semi-permanent, and last 1-3 years.
Would you ever consider this?
