Smiling can rewire your brain to experience more happiness. It activates the brain's reward system similarly to how exercise does. Does this also lead to a healthier skin?
Scientific evidence has shown that we associate smiling with youth and therefore believe a person is younger when smiling. In addition, research suggests that smiling provides an even greater reward stimulus than eating 2,000 chocolate bars. Your smiling muscles send positive signals back to the brain’s reward center, releasing endorphins and serotonin. This creates a joyful cycle instantly, making you feel—and look—more beautiful.
And you know what, even fake smiles have that effect. Therefore, fake it till you make it!
Keep smiling - it's worth it!
