O Spa Brooklyn

The skilled technicians at all of O Spa's three beauty havens focus on fostering whole-body well-being as they tend to skin with more than 10 treatments, including more than 10 massage modalities. Advanced med-spa treatments include laser hair removal with the Eterna Giovinezza by Quanta System, which destroys follicles at the root with its heated rays in 15-minute to two-hour sessions. Permanent-makeup sessions focus on defining facial features with cosmetic tattoos. The areas are first covered with a topical anesthetic to make the experience more comfortable before a permanent-makeup artist inks the lids with faux eyeliner, fills in the brows, or creates the illusion of full lips by tattooing "I Heart Mom" around them.
