What exactly is considered “acne medication?”?

Broad Street Bully asked:


I put money in a flexible spending account, and it’s about to expire, so I was looking up what over the counter meds and whatnot I can buy so it’s not wasted.

It has acne medication listed as an eligible purchase. Does this include things like Nuetragena facewash? Stridex pads? Or is it more limited than that?
