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.
