Hello,
Without examination, confirmation of a diagnosis is tough, but it sounds like Fordyce spots. They are small yellowish-white granules on the inner surface and border of the lips.
Treatment of Fordyce spots includes CO2 laser or electro desiccation, TCA chemical peels (temporary treatment),diathermy or laser vaporization. I sincerely hope it helps. Take care and please do keep me posted on how you are doing. Warm regards.
