Juvederm - what are these white bumps around my lips?

If the Juvederm was injected too superficially, then you should be able to feel the bumps. To make sure you really cannot feel them, try putting some thin oil on your lips. This tends to make your fingers much more sensitive when it comes to palpating small irregularities.

If the lips and bumps are not tender, then I don't think it is very likely that you have an infection. If they are infected, the lips and bumps should be getting bigger and tender and then coming to a head and then rupturing... all very unlikely with Juvederm.

My guess is that these "bumps" represent small glands that were present before, but too small to be seen unless you were really looking for them. Now that your lips are enhanced, they may be bigger and easier to see.

By all means, check with your injector. If your injector took before pictures (which I highly recommend) then you might be able to enlarge the before pictures and compare them to your current after pictures to see if those bumps were there before, just smaller.

Juvederm normally shows up as just bumps or slightly bluish bumps. 

If the bumps are less than 1mm and white, they are likely sebaceous glands. These are normally present on the vermillion (pink part of the lip) border especially on the upper lip.  Usually they are 1mm or less in size and white to yellow in color. 

Sebaceous glands make the oil for our skin and occasionally get blocked.  It is unlikely that these blocked glands were caused by the Juvederm.  They can be removed with aggressive microderm, TCA acid peals or very minor surgery.

Bumps can occur if the filler has been forcibly injected or if a viral infection has occurred.

I recommend follow up with the injector.

Juvederm is a clear gel, and is commonly injected into the lips. This is likely the natural appearance of the skin of your lips, it is simply now more visible since the lips have been augmented. Follow-up with the doctor who performed your injections to be certain the condition is benign, and not an unrelated viral or other skin condition.
