In celebrating its 160th anniversary, Kiehl's is giving itself the biggest gift yet: a spa.

Nestled on the second floor of a new retail store in New York City's Upper East Side neighborhood, Kiehl's Spa 1851 is an extension of the exemplary service the skin and hair care brand is known for.

"It's actually been an idea I've kicked around for the past six to seven years," Chris Salgardo, president of Kiehl's USA, tells StyleList. "It was more of a question of when was the right time. Opening free-standing stores was the priority for us before launching anything else. About two years ago, I saw the location and knew it aligned with what today's shopper wants which is convenience."

The Spa 1851 experience adds a touch of luxury to the quirky, yet cool environment synonymous with the brand's East Village location. "Anything that you would imagine a Kiehl's spa to be, we've nailed it on the head," says Salgardo.

Guests enter through a private entrance off 64th Street and check in with concierge before being escorted to a lounge decked out with wall-to-wall windows. Chandeliers hang in the three treatment rooms and a rainforest photo mural by photographer and artist David LaChapelle liven up the walls. Other spa bonuses include slipping into eco-friendly robes and limited-edition Havianas and iPads to peruse while you wait.

It was important to follow in the apothecary history, so each session starts with a personal consultation similar to one you would get at the pharmacy years ago. Treatments include the signature welcome lavender chest massage. Skin specialists create custom facial and body services that cater to both men and women, and technicians will add extra ingredients right on the spot at no extra cost. There's also a grooming station with two barber chairs where guys can indulge in cuts, shaves and trims.

Prices range from $15 for a mustache trim to $330 for the Ultimate Kiehl's Body Restoration -- which the company's president says will have you walk out of the spa feeling like a totally different person.

When we asked Salgardo what's one of his favorite services, he revealed that he's a big massage fan who loves Creme de Corps. "I never had someone work on my hands and nails like that!" he says.
