Fascinating! It’s good to know that there was one study done and it showed promising short-term results for the participants. My face feels tense, and I’ve been looking to massage and relax it somehow. Now I think I’ll try some form of this happy face yoga and see how it goes! If it gives me relaxation, then I might as well keep at it for the possible benefits to a youthful appearance too. :) Thanks for your article, Allie.
