New Seasonal Service: Naughty + Nice Oribe Charcoal Cleansing Ritual

Whether you’ve been good this year, or a bit naughty, this self-applied, seasonal Experience Room ritual has something for everyone to enjoy.

Consider this your opportunity to precuperate from the stressors of the season.

From the moment you and up to five of your friends step into the room, you’re met with the luxurious signature scent from Oribe, Cote d’Azur. Begin the cleansing ritual by massaging Oribe’s Serene Scalp Exfoliating Scrub into the scalp and cleansing the body with Oribe’s Replenishing Body Wash. After rinsing with the rooms multiple shower heads, buff away dead skin and impurities with an activated charcoal body scrub. After a few minutes, to give the charcoal time to absorb excess oils, rinse off the scrub, and, for the finishing touch, hydrate with Oribe’s Cote d’Azur Restorative Body Crème.

On the day of your Naughty + Nice Oribe Charcoal Cleansing Ritual, you can also enjoy 15% off Oribe’s Body Collection, including Body Wash and Body Crème in three fragrances AND the Cote d’Azur Hand Wash & Hand Crème Holiday sets. While supplies last.

This service will only be available to everyone until December 31, 2025, so don’t wait to spoil your skin!

NEW Yon-Ka Serum Omega soothes skin + seals in hydration

Are you prepared to protect your skin as it’s bombarded by Boston’s harsh winter months?

The latest from the Yon-Ka Paris Intensive line, Serum Omega, acts as the final flourish to your routine. Serum Omega is the final step before applying SPF and makeup.

The Omega-rich formula creates a barrier that seals in hydration and nourishing ingredients from your serums and moisturizers.

This oil-in-serum helps repair and soothe existing damage to inflamed skin and reduces redness and transdermal water loss to combat even the most blustery days Boston throws at us.

Ask your esthetician for more information on how Serum Omega can perfectly punctuate your skincare routine during your next visit.

Great experience!! The staff was welcoming and the space is beautiful. Sasha, works in the spa and she performs my brow tweezing. She does a perfect job! She is the only one I trust to shape my brows! I’m always so pleased.

From day one of going into this spa I was greeted by Dave treated very special all of my needs were taken care of. The staff is professional, respectful and ensure that you have a wonderful time. I love feeling more relaxed than when I came in I so appreciate the staff taking that extra time to make sure that my needs were mad and that I was okay this is what service should look like 365 days out the year.
— Gloria W.
