Do Facial Rollers Really Do Anything? | Greatist

. "Sometimes, you wake up, and your face is a little swollen, and your eyes are a little full. The roller could help move some of that lymphatic fluid and remove some of the inflammation or swelling."

FYI, lymphatic drainage is something your body does naturally—otherwise you would be a very swollen mess on the daily. Lymph fluid is what carries white blood cells and other immune system molecules to areas of distress in the body, and that's where you may see swelling. When those cells have finished their work, the fluid drains away toward the lymph nodes, which filter out the bad stuff and then send the fluid back into the bloodstream.

There hasn't been much in the way of scientific study on the effects of facial massage, but researchers have looked at manual lymphatic drainage techniques on the rest of the body. It does look like massage or movement helps reduce the serum enzymes in the body associated with damage (or exercise) and reduce swelling. You have lymph nodes at the base of the nose, outside the mouth, along the jaw, behind the ears, under the chin, and in the back of the neck, so, theoretically, you'd want to direct the flow of fluid toward those spots.
