Another year has gone by in a blink of an eye. Between the election, the Olympics, the summer of pop girls, and the almost incessant look-alike contests (Timmy, I love you), the past 12 months have been a busy time. Better yet, reward yourself with one of December's Best New Beauty Launches. Add one of these best new beauty launches to your routine and you're bound to end the year on a high note.

Personally, it was Tatcha's brightening serum that got me through the finish line of 2024. This Meghan Markle-approved brand brightened my dullness and transformed my view of what a vitamin C serum should be (but more on that later). Then there were a few new perfumes that became favorites in my vast vanilla fragrance collection and a few hair care discoveries that have now become part of my daily routine.

As a beauty-obsessed editor, discovering December's new releases was a great way to end the year; keep scrolling for the full list of products Marie Claire editors tested and loved in December.
