It is hard to describe the differences in words, but Dr. Jafri has done an outstanding job of it.
To illustrate the differences and simulate this for yourself using an oversimplified technique:
PSP lift: take your left hand and place it palm side down and flatly against your left cheek then pull your facial skin up towards your ear and the neck skin behind your ear.
MACS lift: take you left hand and with your thumb against your cheek bone in front of your left ear, gather all the skin on your left cheek with your fingertips and pull it towards your thumb. When done your should have pulled a circle of cheek skin in your finger tips.
I hope this helps to explain the difference.
