Yoga has been around for a long time and sometimes it seems there are as many different styles as there are teachers. Now we have a new one - facial yoga! Practitioners contort their facial muscles in ways that supposedly ward off gravity and eliminate the need for the needle and scalpal. Sign me up! Please share your experience here if you've tried it!
I have, however, experienced a teacher saying "smile!" during yoga practice. It always makes me laugh. That's got to count as facial yoga! It makes sense though. If we are peaceful and calm due to our yoga practice, it stands to reason that our faces will be too. There might be an absence of lines and creases from frowning but it's got to be hard to keep those smile lines away!
