There's no gym for you face.
You can kind of make up for that by self care. Dress well. Women do like that. And self confidence is important. Not arrogance, but nobody, not just women, likes people who feel sorry for themselves too much. So just talk to them.
If you genuinely are not blessed with looks, it's even more important to do this. Remember you only need to get one woman, not all 3 billion. So once a woman likes you she will stay liking you unless you mess it up. Or you have to break it up because she's nuts. (Be ready for that as self respect is important my friend)
