i have worse skin now than i did 10 years ago, which is saying something. Particularly with scarring. i don't wear make up to work because it's not really very practical with what i do. However, outside of that, if i can be bothered then i do put some tinted moisturiser on to try to mask it a bit; it does make me feel a bit more confident in myself.
If i'm not made up at all i feel like i'm practically invisible. In a weird anti-social sort of way i kind of like that. Invisibility does have its advantages. Also i prefer how my skin feels without make up!
On others i tend to prefer fresh-faced than the other extreme but if someone feels more confident wearing make up then all to the good, i know how that feels. Also love eyeliner on men :)
