Skin by Mamie

Celeb skin-care guru Mamie McDonald has tended to the visages of A-listers such as Iman and Sophie Dahl at her Upper East Side sanctuary. Although she’s moved her operation to midtown, you’ll feel right at home in the cozy space, which contains vintage furniture and pictures of McDonald’s friends and family. She specializes in facials ($55–$325), so clients have plenty of varieties to choose from. Go for oxygen-therapy facials (first visit $235, each thereafter $180), which target blemishes and sun damage, or a minifacial (40mins, $100) that involves a cleanse, steam and mask. The spa also offers services such as waxing ($20–$135) and body wrap–facial combos ($280–$500).
