Following Juvederm for chest wrinkles yesterday, I have long, lumpy lines worse than the wrinkles themselves, is this normal?

While off-label, treating chest wrinkles and crinkles with both neuromodulators, such as Botox, Dysport, or Xeomin, and hyaluronic acid fillers, such as Juvederm Ultra XC and Restylane L, is common practice among experienced injectors. I have been doing so for nearly twenty years. In general, I prefer to treat the entire crinkly field (rather than chasing individual wrinkles) with a diluted concentration of Juvederm Ultra XC. This helps to subtly plump and smooth much of the crinkling and fine wrinkles within the field. Any remaining individual lines, i treat with a diluted concentration of Restylane L. Restylane has less of a tendency to draw water to it, so this works best when dealing directly with individual lines without leaving bumps, which is probably what is going on in this case. Next, a diluted concentration of Botox injected again in a field approach. This is done to work on the lower portion of the platysma muscle within the decollete region, which also contributes to the crinkling. Finally, when surface blotchiness and leatheriness are problems, as they often are from years of sun damage, a series of superficial peels, such as Jessner's solution is recommended along with the home use of sunscreens, retinoids and alphahydroxy acid-containing creams for maintenance. Consultation with a board certified aesthetic core physician with extensive experience and expertise in nonsurgical rejuvenation of the chest is a must.

Juvederm injections in the chest is very uncommon and "off label". The lumpy lines you are speaking of could be from swelling which will subside in 1-2 weeks. If the lumps are still there i would book a follow up with your injector to have the area assessed. 

This use of Juvederm is not typical.  The skin of the chest is very different from the skin of the face.  The lines that you feel are possibly due to swelling, but probably due to the filler.  You may apply pressure or massage to the area and soften the lines.  If this doesn't help, Juvederm can be removed from the area by using hyaluronidase.
