How the Kardashians Changed the Face of Beauty in 2015

After Kendall's heart-hair selfie became the most-"liked" picture on Instagram, fans around the world re-created the image, resulting in the trending #hearthair hashtag.

Kylie and her plump pucker inadvertently caused a viral social media challenge, which saw her fans attempting to achieve similarly plush pouts with suction. Many of them ended up injuring themselves (do not try this at home! Use lip liner instead), and others declared the #KylieJennerChallenge just one more example of cultural appropriation.

After Caitlyn made history with her Vanity Fair cover, she inspired fellow trans women, who created their own faux magazine covers using the hashtag #MyVanityFairCover.
