I think it’s safe to say that TikTok was the social media platform of the year. With over one billion monthly users, the app’s popularity is undeniable. There have been so many niche categories that thrived on the app over the past year and our personal favorite is of course #BeautyTok. Not only did we find some new ride-or-die makeup products, but we also came across life changing beauty hacks (and some questionable ones, too). Below find our seven favorite TikTok beauty trends and products of 2021 — including tricks that will upgrade your routine and products you’ll want to snag before they sell out (again).Hack: Mario Dedivanovic’s Signature Lip Lift TrickGet full, voluptuous looking lips sans fillers with this genius lip lifting hack from celebrity makeup artist Mario Dedivanovic. Using lip liner, Dedivanovic says to focus on overlining the Cupid’s bow and only slightly overlining the rest of your top lip. Similarly, only overline the center of your bottom lip then bring the lip pencil upwards and slightly inside the rest of your bottom lip for a lifting effect. Product: Maybelline New York Lash Sensational Sky High MascaraThis mascara pretty much broke the internet in the beginning of 2021. The lengthening formula, which is infused with bamboo extracts and fibers, helps extend lashes to sky high lengths. Consider yourself lucky if you were able to get your hands on this product in early 2021 (it sold out at Ulta twice!) but if you haven’t tried it yet, it still lives up to the hype.
