Can Dysport Incorrectly Injected Cause Hallowing Under the Eyes and Eye Bags Permanently?

Thank you for your question.  It highlights the need to go to an experienced injector at a reputable place of business.  Fillers are a much better option for the under eye hollow.  Dysport can be used under the eye but is more to relax the muscles and typically low doses such as 3-6 units are used.  It should not cause the hollows to get worse, and it does wear off.  Unfortunately as we age we do lose more volume in our face, and hence the hollows under the eyes become more prominent.

As mentioned by other panel members, the problem was most likely not due to Dysport, as it's effects are only temporary.  Without seeing your photos, Restylane is an excellent option for improving undereye hollows. I recommend seeing a reputable injector in your area to discuss if this is an option.

Dysport is abobotulinumtoxinA, an alternative to Botox, used for wrinkles. When used around the eyes it can help get rid of "crows feet", or the laugh lines near the eye. It does not cause undereye hollows. That is usually a factor of losing volume as you age, your weight loss, and also genetic factors. That region responds well to fillers, especially Restylane, but be very careful in choosing someone with experience injecting this area. All fillers have potential risks, and injection of fillers is not the same as a beauty treatment. It is a medical procedure. In the right hands, fillers can be used to safely fill this undereye hollow, or "tear trough", and results tend to last longer than average in this location. Also, hylaurinic acid fillers tend to stimulate your body to form collagen, meaning you may need less filler in that location over time, and may even no longer require it over time.
