Wei Lang Spa at Devachan 

After the lease on her eponymous three-year-old Soho spa expired, veteran makeup artist turned facialist Wei Lang moved her operation three blocks south, taking over the former Deva Spa space beneath curly-hair salon Devachan. Although the neutral-toned decor remains the same, the focus has shifted toward customized facials incorporating natural products from high-end lines such as Sodashi, YonKa, iS Clinical and Dr. Dennis Gross. Sip gratis organic green tea blended with honey and fresh ginger while you relax beside a soothing glass waterfall in the waiting lounge. Facials such as a brightening vitamin-C version (75 mins, $230) that uses an alpha-beta peel to combat sun damage and a trance-inducing Clé de Peau Beauté Rx style (60 mins, $150), which incorporates Japanese pressure-point techniques and exclusively employs products from the luxe cosmetics brand, are fabulous on their own. But there are also oodles of indulgent add-ons, including firming collagen neck masks ($25) and foot reflexology (30 mins, $75), that can enhance your experience. Seasonal scrubs (30 mins, $165), waxing services ($15–$80), makeup applications ($50–$250), and full-body massages in 60-minute ($150–$165), 75-minute ($180–$195) and 90-minute ($210) increments are also available.
