It's hard to remember a time without beauty giant Sephora, but the retailer is only a teenager. To celebrate its "sweet 15" this month, there's a party every Saturday from June 8 through June 29 at every (yes, every) Sephora location nationwide. There will be makeovers, skin consultations, great music, and yes, even presents.

If you're really only in it for the swag (no judgement!), here's the scoop: June 8 is makeup bag makeover day -- when you spend $50 you get a free makeup bag. And on June 22 they're giving out free tote bags with a $50 purchase.

If you can't make it to a store, Sephora is also celebrating on Facebook with -- what else? -- a sweepstakes. The grand prize is a trip for two to surf camp in Costa Rica (!), and a one-year supply of Bumble & Bumble Surf hair products. Enter here.
