I had this lip line pimple like 2 months ago and I popped and it hurt but the bump went away and the redness is still here will stay like this forever?

Maybe. If it is just some redness due to the trauma of popping the bump, it should fade over the next few months. However, trauma can sometimes cause new blood vessels (telangiectasias) to form which could be more permanent. Patience and sun protection are my short term recommendations.
