Believe me, of course! The glands visible on the lips are not there in most people--that's why they look different when some people have them.
Here's a quote from a major skin textbook, published this year:
Fordyce granules are sebaceous glands that are located in the vermilion zone of the lips and the oral mucosa. Historically, these sebaceous glands have been considered ectopic[MEANING: they don't belong there]; however, because they are such a common clinical finding in the oral cavity, Fordyce granules should be regarded as a variation of normal anatomy. They can also be found on the vulva.
Epidemiology
Fordyce granules are found in both sexes and are less common in children. The prevalence of Fordyce granules ranges from 70% to 84% of the population.
If you're unsure of exactly what you have, please let a dermatologist have a look in person.
Take care.
