Spring is here and so are savings on your favorite beauty essentials. From low-key faves to try out at a discount, to high-key obsessions to horde, they're all here. Ulta is slashing prices by 30-50 percent and La Roche Posay is offering a generous 15 percent markdown. If you're not a member of Sephora's rewards club, now is a good time to join, their 15 percent off sale starts April 20th.
