Dysport and eye bags. Will a gentle massage in the area help dissipate the fluid retention?

Massage is generally not recommended after treatment with botulinum toxin, because of the risk of diffusion of the toxin to the nearby areas.You will be better off sleeping with your head up, and using cold packs.

Thank you for your question. It is common for the periorbital (around the eye) area to swell after any procedure. Dysport, as you know, is a neuromodulator that has a specific range of effectiveness after it is injected. Therefore, I would resist the urge to massage the area, as you can theoretically move the product, which may lead to an undesired result. Sleeping propped up is a great idea - the face has an excellent lymphatic / drainage system and this should resolve shortly. If you are prone to allergies, or have puffy eyes to begin with, an antihistamine may also help to quiet things down. Best of luck! 

 I would not recommend massage. This would relocate the toxin into an area that you do not want it.  I never recommend, nor perform, and Jack Shands it was a criminal of botulinum toxin into the lower eyelid or upper cheek.  This is because it can cause lid droop, and difficulty smiling, as most of the smile muscles attach in this region.   The problem with "fluid" may be due to the dilution that your injector is using. Dr David Mueller

If there is Dysport in those areas it is probably not a food idea to massage them. The reason for that is that massage might cause the toxin to migrate to other nearby locations where an undesirable effect might ensue (droopy eyelid etc.).
