A-list Facialist Joanna Czech reveals her secret weapons

We’ve decided to spill the beans on one of Hollywood’s best-kept secrets. (After all, why should tabloids have all the fun?) Her name is Joanna Czech, and her facials make the A-list sparkle.

Clients
Czech’s client list practically needs its own red carpet: Penélope Cruz, Uma Thurman, Christy Turlington, Kate Winslet, Laura Linney, Cate Blanchett and Kim Cattrall are just some of the famous faces who head to her private studio at Paul Labrecque Salon and Spa in Midtown’s Core club for bespoke combinations of L.E.D. therapy, Sapphire (an exfoliation treatment that uses granules of the stone to erase fine lines and tighten skin), ultrasound water peels and soothing facials that incorporate products from Nude and Environ, two of her favorite lines. She also gives a mean bikini wax.

Secret Weapons
Cleanliness is next to goddess-ness. Czech recommends using a pristine washcloth to sweep Nude’s Cleansing Facial Oil ($36 at Barneys New York) over your skin before bed. ‘‘The cloth adds mild exfoliation to the cleansing process,’’ she says.
