In other words, this is the perfect opportunity to score an excellent deal on everything you’ve been eyeing for your beauty cabinet, including investment purchases and holy grail restocks.
With three whole weeks of epic beauty offers, there’s a lot to choose from. Luckily, our team of editors has combed through the entire sale calendar to highlight the deals truly worth your attention — and your money. Expect rare discounts on everything from premium hairstyling tools to signature scents, and first-time savings on new-to-sale brands like Polite Society, Kylie Cosmetics, NARS, Sacheu, and many others.
