While Yves Saint Laurent, one of the greatest fashion designers that ever existed, is sadly deceased, the brand lives on. So in honor of his birthday, we’re celebrating with YSL’s best-selling beauty products. From the Touche Eclat pen (aka the most amazing concealer we’ve ever used) to luxury nail lacquers, these gems are definitely worth the splurge. Plus, if you can’t afford his couture duds, a YSL designer lipstick will make you feel like a million bucks. Check out the slideshow above to see 10 of YSL’s best-selling beauty items. Which one is your favorite?
