Is infrared light good after facelift?

I don't believe there is any scientific study to prove that infrared light will help with neck swelling after a hematoma and a facelift, but it shouldn't hurt anything. Infrared light only penetrates a very short distance into the skin, so more than likely, you just need to be patient. Any residual swelling will slowly go away over the next few weeks.

is to be expected. As long as the swelling is reducing and not caused by anything treatable then more often than not patience is key. I use various modalities to 'treat' prolonged swelling / hardness / discolouration. These are included in my fees and range from Ultrasound, lymphatic drainage, Pulsd dye laser, infrared light etc. Every surgeon will have their own preference. 

It is possible to get a hematoma after a facelift, and after this is treated, that side of the face can take longer to heal than the other side.  I am not aware of any scientific data showing that infrared light would be helpful to reduce swelling or help healing after a facelift which involved a hematoma or not.  It most likely is just a matter of time for the swelling to resolve.
