Luckyscent
If there's ever been a hard-to-find, exotic, or celebrity-favorite fragrance, Luckyscent.com probably has it. The boutique scent site caters to the most discerning customers (like Sarah Jessica Parker, who shops the site for L'air du Desert Marocain). Try a sweet scent like Dulcess, Monyette Paris (Cameron Diaz, Gwen Stefani, and Katie Holmes are just a few of its fans), or Jus d'Amour (which Vanessa Wiliams and Sharon Stone have sampled), or find yourself in vanilla heaven with luxe picks like cult-favorites Tihota or Madera, which will make you feel like a star.

This research-based Swiss skincare line is focused on Oxygen products, and celebs like Victoria Beckham, Sarah Jessica Parker, Cameron Diaz, and Uma Thurman all share a love of its star product, the Vita-A-Kombi face cream. The cream (available in three strengths) delivers Oxygen and vitamins to skin, for a clearer, brighter complexion. Level One is good for beginners as an all-over brightening moisturizer, while Level Three is a potent zit-zapper best for spot treatments. Many of the same stars also use the brand's cellulite creams -- the so-called Dynamic Duo of Silhouette (which disperses fat by forcing Oxygen into the skin) and Tonus B12 (a slimming anti-inflammatory cream that reduces excess fluid).
Keratin Treatments
From the long-lasting Coppola Keratin Treatment to the newer, shorter-effect Brazilian Blowout, celebs have embraced salon keratin treatments for smoothing unruly hair. If you can't afford one yourself, stylist Ryan Nickulas of NYC's Ryan Darius Salon recommends purchasing a professional keratin product to use at home. "The benefits of products like Keratin Complex's Infusion and IntenseRX are instant," he says. "These two products infuse keratin into your hair and help reinforce the protein that most hair lacks due to environmental damage, over-processing, or heat styling." Nickulas recently used both on Pamela Anderson's hair, which he then blow-dried and set on jumbo hot rollers for her signature glamazon look.
Cartier Panther Head Ring
By now, you've probably seen the outfit Lady Gaga wore to her sister's high school graduation. But you may have missed one of her more demure (comparatively) accessories: The Cartier Panther Head Ring. This 18K yellow gold and onyx ring is modeled after one of Cartier's signature style staples -- the panther -- and features peridot eyes (how chic!). It retails for $20,300 -- looks like Gaga splurged a little to reward herself for all of her hard work.
