Licking your lips won't really make it any worse.
The Fordyce spots will appear eventually if your lips aren't healed by the next year or so.
It looks like you're in the early stages, so the sooner you heal the better otherwise it WILL get worse and it WILL ruin your life. I've seen people on this forum who have this condition for over 10 years. Trust me man even one year with this condition is enough to make you suicidal. I don't mean to scare you but that's the reality.
Mine was caused by constantly biting the skin off.
Maybe you took some medication that dried out your lips? That's what happened to some here.
Keep what you're doing for a few weeks to see if there's improvement. If not then you gotta try something else.
