I'm prone to comedones around my lips. Recently im getting puss filled zits around the edge of my lips. Any ideas why/suggestions to prevent/treat it?

Are they comedones? If you are certain that the bumps are comedones (white heads), the otc retinol creams nightly can help (eg. Roc retinol). However if you have whitish bumps on your lips, they are likely oil glands called "ectopic sebaceous gland". These will not go away. Some remove them cosmetically with lasers. Seeing your dermatologist can help you determine what these bumps are.
Viral. It sounds like a herpes simplex infection. See your doctor, topical or oral antiviral medications will clear it up.
