I posted this on the other Say It thread before remembering that this one exists now:
So annoying. Another forum I'd only joined to make one post apparently has no way to deal if you forget your username, so I can't reply to tell this chick that no, she's not "always protected" because she uses SPF15 foundation. I'm sure she doesn't glop on more every 2 hours. The non-sunscreen-user she thinks she's doing so much better than gets far more sun protection than her on a daily basis because she doesn't lull herself into a false sense of security.
...It's a siggie
