The only one no one mentioned is Make Yourself sleep on your back, or propped up a little with pillows. It reduces puffiness in general, and will eliminate "sleep wrinkles", especially on neck, chest, and sides of eye sockets....
Also, drink a Ton of water to flush all the salt through your system. These are tried and true, real fix/ preventatives.
(And Regenerist is an amazing product line, all of it). Prep H is a temporary fix, use for short term reduction of swelling ...just like on your ...other end.
