Introducing Halo Dual Skin Therapy
A Halo Dual Skin Therapy session pairs halotherapy and red-light therapy to amplify the benefits that each modality can provide for improved skin health. These dual therapies work synergistically to address issues for people with skin conditions like eczema, psoriasis, acne, and dermatitis.
Skin benefits of Halotherapy:
The particles of salt, about the size of red blood cells, have anti-inflammatory and anti-bacterial properties that reduce redness and destroy acne-causing bacteria.
The salt also exfoliates the surface of the skin, helping to remove dead skin and unclog pores.
As the salt settles on your skin, the particles attract and retain moisture, hydrating and improving your skin’s pH.
Skin benefits of Red Light Therapy:
RLT works from the inside out, improving skin cell function that may be affected by conditioners like eczema.
RLT has anti-inflammatory benefits, reducing redness and itchiness.
RLT can also boost collogen, further helping to retain moisture in your skin.
These effects can only improve exposed skin, so for the first time we are offering our clients additional privacy that is not available during a typical Halotherapy session. If you book the Halo Dual Skin Therapy service, the salt cave is reserved just for you and up to one guest to join you. In order to ensure your comfort, you will not be booked with people you do not know.
As an added bonus, you still receive all of the respiratory benefits of halotherapy as well. For those unfamiliar with the respiratory benefits, in short, inhaling fine salt particles draws out allergens and other irritants to clear your airways and help improve a number of respiratory conditions.
This service is intended to manage symptoms and compliment care prescribed from your doctor and is not a cure for these conditions. It is recommended that you avoid using red light therapy until a flare up subsides. For the best results you should book multiple sessions, but no more than 2-3 per week. Consult your doctor to discuss whether this service is right for you.
Halo Dual Skin Therapy includes both therapies working simultaneously over the 20-minute service, with 20 minutes of Halotherapy and 15 minutes of Red Light Therapy. Each session is $45 per person.
The first 10 clients who receive this service will get a complimentary full-size Yon-Ka Phyto 152. This hydrating body creme, enriched with rosemary, helps firm the skin for a refined silhouette. For those treating severe conditions or experiencing a flareup should consult their doctor before using Phyto 152.
As of April 1, 2026, members can substitute any of your complimentary Halotherapy sessions with Halo Dual Skin Therapy each month.

2 Ways to Step Up Marathon Prep/Recovery
Reward yourself for your inspiring efforts to conquer heartbreak hill.
When Marathon runners book a massage or pedicure that will take place in the month of April, they can receive one of two options:
50% off a contrast therapy session, featuring our cold plunge and red-light therapy
or
a complimentary Halotherapy session in our Salt Cave
Just show our concierge your 2026 Boston Marathon registration, bib, or medal, and unlock an upgraded marathon prep or recovery experience.
Not sure which option to choose?
While both options are perfectly suitable for before or after the big day, consider the complimentary Halotherapy session for appointments before the marathon. Some athletes are working Halotherapy into their regular routine because, by clearing out the respiratory system, it can help improve the oxygen exchange and resilience against lactic acid build up.
While cold plunge therapy could be a great way to recover from your training leading up to race day and red-light can help delay muscle fatigue, consider the post-race benefits of flushing lactic acid and reducing inflammation (amplified by the red-light therapy) in the cold plunge.
Whichever you choose, you really can’t go wrong. Once you try either, we have a feeling you’ll want to make it a habit. Ask our concierge about purchasing a series for additional savings on future Halotherapy or Contrast Therapy services.
*Subject to availability. Only applies for 2026 Boston Marathon runners receiving a massage or pedicure in the month of April 2026.

Marathon Runner Gehwol Giveaway
This offer is entirely on us. No purchase necessary.
We want to make sure anyone running this year’s Boston Marathon is adequately prepared to care for their feet ahead of race day. Those 26.2 miles put your whole body through extreme stress, but you may be overlooking one preventative measure that could help fortify the skin on your feet. Gehwol’s Footcream, for tired feet and skin, protects exhausted skin and prevents aching feet, chaffing, blisters, and excessive sweating. Just apply a 1mm thick layer to your feet, opt for thicker socks, and hit the pavement.
This is also a great product for hikes or other activities that cause your daily steps to spike.
We encourage you to come by soon so you can incorporate this into your training leading up to race day.
All you have to do is show our concierge your 2026 Boston Marathon registration, bib (or medal, if you decide to wait until after the marathon), and get a complimentary full-size Gehwol Footcream.
*While supplies last. In-store only.

April Showers
As we leave a very snowy winter behind and welcome the warmer, brighter days, we look for opportunities to reconnect with friends and family. G2O’s Experience Room is the perfect place to do just that.
Both the Bali Revitalizing Ritual and Rasul Purifying Ritual, the two most popular, self-applied wellness experiences, create the perfect, sumptuous atmosphere to unplug and unwind while you steam and socialize.
In each ritual, herbal steam gradually envelopes the space as color light therapy regulates your mood and reduces stress.
The Bali features a self-application of hydrating, fruit extract crème to soften and moisturize the body followed by an herbal salt self-exfoliation.
The Rasul includes five self-applied Rasul muds, customized for the body, detoxify, purify and replenish the skin with minerals during an herbal steam treatment.
A cooling mist and invigorating tropical rain conclude both of these sensory-rich rituals.
To help facilitate this much-needed in-person connection, this April, when you receive either the Bali or Rasul for 4 people, G2O will cover the cost of 1 guest. You only pay the price for 3. That’s a $75 savings.
We can’t wait to see you and some of your favorite people soon!
Call/text 617.262.2220 to book now.
*The service must take place in the month of April 2026 and only applies to groups of 4. Subject to availability.

2026 Brings Major Membership Upgrades
Enjoy massive improvements to our award-winning Membership Key offerings beginning January 1, 2026!
Guided by all of your valuable feedback, we’ve simplified our offerings, identified the perks that matter most to you, and made them more attainable.
For starters, there are two tiers of general memberships. To put it simply…
Our Essential Wellness Key, is staying exactly as it was in 2025, including the price of $179 per month.
The second tier, our reimagined Serenity Key, offers you (among other things) 15% off ALL services. That perk is something that, as of 2025, was only available as part of our $360 per month membership. As of January 1, 2026, you can now get that same perk for ONLY $199 per month.
If you currently have the Essential Wellness Key and want to upgrade, let our concierge team know when it’s time to renew, and enjoy 15% off all services, 3 additional complimentary Halotherapy sessions per month, + more!
We’ve also reimagined two Specialty Membership Keys.
The Recovery Key, which is the perfect fit for athletes or those with an active lifestyle, now features 3 additional Halotherapy sessions per month, 1 additional Cold Plunge session per month AND a brand new perk that gives you 25% OFF all subsequent cold plunge, Halotherapy, or aromatherapy steam sessions per month! With all that added value, the price is staying the same at $195 per month.
Our second Specialty Key, the Oasis Key, is our ultimate amenities pass. With a new lower price of $299 per month, enjoy unlimited access to our amenities ANY DAY Tuesday-Sun, not just on days you book a service. In addition to a lower price, we’ve increased the number of complimentary Halotherapy sessions per month. And don’t forget, this is the only membership key that gives your guests a 10% discount for select services.
These improvements will go into effect as of January 1, 2026, not just for new members, but for existing members as well!
