I've had these small bumps next to my nose for about 7 months now and I haven't had the time to go to the dermatologist to check them out. They're raised skin/bumps that aren't acne or pimples because they have no puss or anything in them. They seem to not go away at all because it's been a long period of time, yet none of them have left. They also are a bit glossy at the top.I've come to the conclusion that they're milia . But milia are whiteheads and are near the eye, which is not true in my case. Sorry for making this description so long but my main issue is:
What are they?
How should I treat them to prevent them?

Thank you for your time!
