Do you have a femstache, that is, a fringe of hair on the upper lip? Removing most of the hair on a woman's face (except her eyebrows) is considered part of good grooming. Women with mustaches are objects of derision because of that cardinal rule, but if you ask me, that cruelty is unfair and underserved! I think women have the right to keep their hair if they so choose, as long as said hair is clean.
All things considered, I choose to keep my upper lip hairless. The face is simply brighter and clearer that way since even a faint fuzz of fine hair can cast a shadow, thus making skin look uneven. Before, I denied the existence of my femstache. I thought nobody can see it - but it's one of those things we just gloss over until someone calls it out. And someone did call it out.
Since then, I started either plucking or shaving my stache. However, plucking is painful and shaving gives that sensitive area chicken bumps. So I get lazy. That is, until I discovered the joys of DIY waxing. It made the process faster with less side effects so now I do it regularly.
I like using the Veet Ready to Use Hair Removal Wax Strips, the small ones for fine hair. It's easy to use and can remove most of the hair in two swipes.
