Score two for the price of one, or mix and match your buy-one-get-one deal with other brand's mascaras as well.

How cute is this collaboration? We can see why these hair brushes are a celebrity-favorite. "I love, love the Wet Brush products," Kyle Richards raved in her Amazon guide.  So, so, so, so good."

Paige DeSorbo's best secret to moisturized skin all year-round? This First Aid Beauty Ultra Repair Cream. "If you’re really dry and your skin is crackling and hurts, this is the best," she says. "This truly works so well." Fan of the brand? The full line is 25% off right now at Ulta.

Jennifer Aniston's award-winning haircare brand has earned cult status with this spray-on detangler that adds shine and removes tangles effortlessly. "I swear by the Glossing Detangler. It's like a beauty trick in a bottle," says Aniston. 

The viral pimple treatment officially gets a celebrity co-sign from Vanderpump Rules star Lala Kent. "This is another game-changer. Just stick a Q-Tip in there and dab it directly onto your pimple. I love this stuff. It's the best," she said in an Amazon Livestream. 

The beloved SPF brand continues its strong legacy with fans of its bestselling Unseen SPF including Shay Mitchell. "I never leave the house without sunscreen so have literally tried them all but lately I have been into the Supergoop Unseen Sunscreen," Mitchell told E! News.

We've simply lost track of all the celebrities that rave about this cleansing balm. Notable names? "Ciara [Miller] introduced me to this on Summer House. It literally melts all my makeup away," says Paige DeSorbo.

If you're not yet familiar, meet the eyelash serum with a lengthy celeb cult following, including stars like Vanderpump Rules star Lala Kent,  Selling Sunset's Heather Rae El Moussa and Summer House star Paige DeSorbo saying, "I used to get eyelash extensions all the time. Now, I just use the GrandeLash serum. Being able to rub my eyes every single day without worrying about messing up lash extensions is everything."

Celebs obsess over this body oil, with stars like Lala Kent saying, "I'm obviously obsessed with my Bio-Oil Products," she told E! News. "Every time I say the word ‘oil' in skincare people want to run and hide because they think that means clogged pores, but I use Bio-Oil for so much... on my bump... on my face, neck and chest."

A new perfume has hit the villa, and it's from none other than the Hot Girl herself, Megan Thee Stallion. The star's new fragrance features a refreshing fruity and floral blend with notes of passionfruit, pear, sandalwood, and more.
