Guerlain Spa Boutique @ The Waldorf Astora

Thought you could only find Guerlain at Sephora? Guess again. The luxury beauty brand is took things one step further and opened its first US store at the Waldorf-Astoria. Fans of the brand can find fragrance, makeup, and skincare products like the crystal-topped Insolence perfume ($62) and L'Or Radiance Concentrate ($68), which actually contains real gold to moisturize and smooth skin. You can also get a facial or a makeup application. The boutique will also allow visitors to book spa treatments and use gift certificates from the spa. Now that's a boutique that's worth its weight in gold.
