Why Does Juvederm Leave a Bump After the Injections?

When dermal fillers are injected the material expands the surrounding tissue. This is normal, and may cause some raising of the skin surface.
Over a few days this subsides to a flatter surface, while maintaining the cosmetic improvements for the life of the filler. The duration of the filling effect will vary with the type, location, and volume of filler used.

Some patients develop a small skin bump right after the injection because that's how their body responds to a skin injury (from the needle) and goes away in a day and is unrelated to the filler.  Other times, the bump can occur as a result of too much product in that area.  Gentle massage over time will make this better.  Juvederm is a very cohesive filler and can 'clump' sometimes.  Ask for a less cohesive filler next time and let your provider know about the bump so they can alter their technique to avoid too much product in an area. 

This little bump is usually caused by the injection process, due to the needle piercing the skin. It goes away in the day or two after your treatment. A gentler injection technique can be performed to reduce the size of this bump.

It’s not unusual for small bumps to occur following Juvederm
injections. These bumps occur at the
site of the injection and are related to the injection technique. When Juvederm is injected close to the
surface of the skin these bumps commonly occur. They can be prevented by avoiding superficial injections. Once they occur, they can be treated with
massage. In most cases, a response is
generated within a week following this maneuver. If
you’re concerned about this problem you should consult your physician. Your physician should be able to make an
appropriate recommendation.

I don't usually get any bumps with the injection. If placed too superficial, irregularities can occur. If the bump is not gone in a few days then I would question the injection technique.

The technique that is used to inject the juvederm is what is resulting in the lumpines or bumps.  The skill of the injector is very important.  Make sure that the person injecting the Juvederm is a board certified plastic surgeon. Nurse injectors just do not have enough skill, training, education, or expertise to inject fillers.

It sounds like the bump could be due to swelling
or bruising from the injection itself. If it is bruising that forms, I would
recommend using arnica gel, which is a herbal remedy that can help to minimize
swelling and bruising after your treatment. I would also recommend that your
physician apply ice prior to your treatment to help minimize your risk of
swelling.

After the product is injected into the skin, it expands with water. If the injection was placed too close to the skin as the needle is either introduced or withdrawn, then it can leave a small bump at the injection site. For best results look for a very experienced injector.

Juvederm is a hydrophilic filler, meaning it absorbs water early on.  During the early period a slightly palpable bump (but not visible) is a normal outcome.  After a few days, any bumps from the filler should be smooth.  If bumps persist, the injector may injected too superficially near the skin and placed too much filler in an area as well.  Filler injection is as much an art as it is a science.

Thank you for your question. In my practice, it is very uncommon for patients to have any palpable lumps or bumps after filler injections. If this is happening each time you receive fillers, with the same practitioner injecting, perhaps you should try out a new injector. There are specific techniques used when placing fillers so that these issues are specifically avoided. Best of luck!
 

If there are bumps present this is usually caused by the injector (Physician) not the dermal filler.  If there are some bumpy areas they can be massaged out. Good technique is essential.
