Celebrities are under a lot of pressure to look gorgeous all of the time, so most of them have researched the best products and use only what works for them. Because they can afford to spend a small fortune on products, they often do. Lara Spencer lets us in on some celebrity beauty secrets. You'll be surprised to learn a few of their most treasured products can be found at an average drugstore!

Bronzers and Self-Tanning Lotions

Mariah Carey is the queen of the perfect tan and she's not afraid to spend for it. She's currently developing her own line of bronzer that has 24K gold dust in it for added "glow!" For those who can't afford to cover themselves in gold dust (or who just have no interest in looking like the girl from Goldfinger), try Lancome's Soleil Flash Bronzer ($26) or Sun Laboratories' Tan Overnight ($15 -- click on the link for a Buy 1 Get 1 Free special).

Eliminate the need for hose with Airbrush Legs ($4), a tanning spray recommended by none other than Diane Sawyer. Airbrush Legs can be found at any drugstore but it sells out fast so make sure to stock up if you find it!

Mascara

The Olsen twins have been known to shell out $600 for a single tube of mascara. For them, it's what's on the outside that counts -- 24 hand-set Swarovski crystals and an 18K gold top! If you're looking for a great mascara sans jewels, however, stars like America Ferrara and Chandra Wilson swear by Maybelline's Great Lash Mascara, which costs around $5. "You'll find it in every celebrity makeup bag," says Lara. "I don't care what they tell you or what they're endorsing, they're using this!"

Skin Care

For celebrities like Naomi Campbell and Madonna who can afford to spend $2,100 for lotions and creams, the skin care regimen of choice is ReVive's Anti-Aging Combo. For the rest of us, Consumer Reports put its seal on Oil Of Olay's Regeneriste line of products.

Teeth Whitening

Lara swears by Supersmile Quikee! After a glass of red wine or a cup of coffee, place a drop on your tongue. Your teeth will be sparkling in no time, and your breath will be minty fresh too!
