Whether or not you're excited about the impending sweater weather, the new beauty products launching in September 2021 are reason to be excited about the season change. While brands drop products every month, September is arguably the Superbowl of beauty, when the most innovative, game-changing formulas hit virtual and IRL shelves.

While it might not be cold enough to experience the drying effects the crisp fall air can have on your skin and hair just yet, launches like Youth To The People's non-stripping chemical exfoliator and Dyson's Flyaway Hair Attachment for its Supersonic Dryer will both come in handy as the weather starts to shift as the month goes on.

And since wearing face masks isn't going to stop any time soon, Hanahana Beauty's detoxifying mask can help minimize clogged pores, which can lead to maskne, and Lancôme's metallic, jewel-toned eyeliners are ideal for easy, yet impactful eye makeup looks.

For complete details on all of these products and more, keep scrolling for the 15 best new beauty launches of September 2021.
