The 10 year challenge goes by many names: the #HowHardDidAgingHitYou challenge, the aging and #GlowUp challenge, though the movement has picked up the most speed as posting an image from 2009 and a recent one from 2019. The overall message? Self love and showing the world how you've "gracefully age."
