The lipstick, as I said, is for show. A circus performer uses it for part of her act, same with the nail polish and any other dust cosmetics she would use. For actual combat she uses phials.

Actually, come to think of it, we don't know how much dust is needed to be effective as an energy source so depending on how much if the lipstick is dust and how much is parafin/wax/whatver it could be mltiple uses without fully depleting (Weiss spamming massive walls of ice without an noticeable change in Myrtenaster can give us some idea, does not need a ton)), just make the color fade a bit with each use. Considering she uses to conjure weapons single use is all she really needs, just re-apply between fights since you won't exactly be ditching them mid battle.
