Why Does Restylane Swell So Much More Than Juvederm?

Thank you for your question. It is very common for the lips to look
over corrected or fake the next day. This is due to all the swelling
that ensues. I often tell my patients that this
is the "oh my gosh" day. It can be 'oh my gosh' my lips are so
swollen! It could also be 'oh my gosh' I love my lips even more than
yesterday. Either way, the swelling may last a few days with every day
showing a decrease
in swelling. The more you ice the first day or two, the less swelling
you will have. I would wait a few days to a week and then return to
your injector if you still have concerns after that. If you like the
look of the lips at some point during the swelling reduction, then take a
picture. This way you know what volume you like in the lips for the
future.I believe that the swelling can be both due to the nature of the product as well as the technique of the injector.  I do a lot of training for other injectors and find that the more manipulation of the lip while injection, the more swelling one gets.

Both Restyllane and Juvederm contain the same basic chemical component but are marketed by different companies. in all likelihood, the critical distinction between your reaction to the two treatments is the technique used by the physicians. Both products should produce similar results; as for physician preference, it is like the difference between Coke and Pepsi. Some physicians opt for Juvederm because of preferential pricing and others for Restylane for precisely the same reason!

Both Juvederm and Restylane can cause, in very rare circumstances, excessive swelling in the lip areas.  There may not be a difference in the two products in terms of swelling.  Restylane is more particulate and can be used when greater structure is needed to lift a tight crease but Juvederm is nice to provide a smooth lip augmentation.  Restylane also produces smooth lips though, and ultimately, it is up to the physician to decide what they prefer to use and answer your questions about alternative fillers.
