When: At night before sleeping.
Duration: 5 to 10 minutes.
Step 1: Sit on the bed start making faces- just as small children do: good, bad, ugly, beautiful- so the whole face and musculature start moving. At the same time make nonsense sounds and sway.
Step 2: Go to sleep.
Step 3: In the morning before you take your bath, again start before the mirror and for 10 minutes make faces. Standing before the mirror will help you more will be able to see and you will be able to respond.
