Best Needle-Free Wrinkle Removal

Collagen. Noun. Definition A: a class of proteins that forms connective tissue between cells in the skin. Definition B: the extra guest at any Real Housewives dinner party. Definition C: the main ingredient in the new collagen facial ($150) at Equinox (225 Franklin Street, Boston, 617.426.2140; 131 Dartmouth Street, Boston, 617.578.8918). A transparent mask of the stuff leaves skin soft, hydrated, brightened, and with fewer fine lines. (It's like being kissed by an angel - or at least Angelina Jolie.) The treatment is available in both Boston locations, but we recommend heading to the Franklin Street address and requesting esthetician Tereza Pupeza. She's inspired by her extensive world travels and often makes her own cleansers, lotions, and other products using recipes handed down by her mother. And her tableside manner is complemented by one of the best décolletage massages we've yet to receive.
