After Juvederm, Top Lip Developed Little Saggy Flaps - Is This Normal?

It may be that you have an overcorrection of filler towards the corners of the lips rather than swelling, but without an examination I couldn't be certain, but swelling usually does not appear this way.  If you still want fuller lips in the center, I would advise that the corners of the lips not be as voluminous as they are currently as there needs to be a taper from middle to outer upper  and lower lips.   It would probably not be helpful to massage unless it were very recently that the Restylane or Juvederm was used. You may consider to have the filler dissolved with hyaluronidase and then see an expert in the use of facial fillers to start from your baseline.

Lumps after Juviderm are unlikely to be improved without injecting them with hyaluronidase to dissolve them. Fat is a better alternative to make the red part of the lips fuller by a surgeon very experienced in this technique.

Eton,

If you look at many celebrities and people who have overdone lips, this lumpy look in the corners of the upper lip is very common. It is what happens when the doctor (or the patient) tries to achieve a fuller lateral lip than the patient's natural anatomy can handle. When you asked the doctor to fill out your lip sides, you may not have realized this was what it could look like--and the doctor did not do a good job of warning you. I would wait at least two or three weeks, let any swelling go down, gently massage the areas, and only then decide if you still dislike it. If you do, you can go back to the doctor to have a consultation on what to do: dissolve filler, add more to the middle (if you really want your lips looking fuller than it seems they already do), or just wait it out with lesson learned for the next time.
