Amazon is kicking off the season with its highly anticipated Big Spring Sale - and it's shaping up to be a major moment for beauty lovers. Running from Wednesday, March 25 through Tuesday, March 31, the massive shopping event is packed with steep discounts across skincare, makeup, haircare and more, starting at just $3. While you can browse all the beauty deals on Amazon's main Big Spring Sale page, consider this your shortcut to the best beauty finds actually worth adding to cart.
