Using a massage roller is great for reducing facial swelling.

It's a mini massage roller~ My face used to get all puffy the next day even if I ate just a little bit of salty food in the evening! An acquaintance uses a massage roller every day and said it was great, so I bought one to try out^^

If you massage repeatedly from the tip of your chin upwards towards your ears, it helps manage your jawline and also reduces swelling.

The prices vary widely, so I plan to try a cheaper one first and repurchase later.
