10 Products NewBeauty Readers Couldn’t Stop Buying in December

Sacheu Peel Off Lip Liner STAY-N ($12)

When Billie Eilish dropped her beauty routine last month on TikTok, we all took notes. In addition to MERIT Beauty's mascara and highlighter stick, a Tower 28 lip liner, a Makeup by Mario eyeshadow palette, a $10 Maybelline eyeliner, and more, the two-time Oscar-winning singer started her lip look with the viral Sacheu Peel Off Lip Liner STAY-N.

RMS Beauty Lip2Cheek ($36)

We compiled a list of shoppers' favorite blushes for mature skin and then our readers scooped up RMS Beauty's Lip2Cheek in droves. That might be because the creamy formula contains skin-conditioning ingredients like shea butter, cocoa butter and Buriti oil to hydrate both lips and cheeks with concentrated colors that build and blend seamlessly.

Tarte Creaseless Creamy Concealer ($30)

Winter is the season when we all swap out our lighter moisturizers for richer formulas that will combat drier air, indoors and out. It's also a good time to try a hydrating concealer—especially if you're prone to dry under-eyes. One option beloved by shoppers? Tarte's Creaseless Creamy Concealer. "At 52, I have fine lines around my eyes, but this concealer works like magic," says one reviewer. "It blurs those lines beautifully without settling or creasing."
