We're forever indebted to Amazon Prime Day, because in addition to these once-a-year sales on smart tech gadgets and incredible kitchen tools, the annual retailer is also offering us beauty junkies the Hollywood treatment. So far, we've scored 25 percent off Mario Badescu's cult-favorite rosewater facial spray and thirty percent off this Olaplex treatment -- but the steal we're most psyched about is definitely the Clarisonic Mia Brush

The tool, which has been proven by dermatologists to provide a plethora of anti-aging and exfoliation benefits, has become a cult favorite for the Hollywood elite. In fact, everyone from Kellie Pickler to Fergie, Faith Hill, Emmy Rossum to Sophia Bush, and even the cast of Entourage, is a fan of the product. 

Not only does it reduce puffiness, but the best-selling product lessens the appearance of pores, fights wrinkles, firms skin and removes 99 percent of dirt, makeup and oil. With an $80 markdown for Amazon Prime Day, we're very much sold.
