Two experiences — a complete Metabolic Reset Protocol with an exclusive follower bonus, and float-only deals for every level. All through Steph's link.
Non-invasive cryotherapy body sculpting that freezes fat, tightens skin, and reshapes your body — no needles, no drugs, no downtime. Combined with floating and a guided lifestyle reset, this is the most complete body transformation program we offer.
Non-invasive · No needles · No downtime · ~30 minutes per session
Body sculpting at Float Boston uses localized cryotherapy — controlled bursts of extremely cold air — to target and break down stubborn fat cells in specific areas of your body. Fat cells are uniquely sensitive to cold in a way that your skin, muscle, and nerves simply aren't. When exposed to precise cold temperatures, fat cells undergo a process called cold-induced apoptosis — essentially, programmed cell death — while everything around them stays completely unaffected.
The result? Your body naturally flushes the treated fat cells through your lymphatic system over the days following each session. There's no surgery, no injections, no recovery time. You walk in, you get treated, you walk out — and your body does the rest.
Unlike body contouring machines that use suction or heat, our Kaasen system works with precise temperature control so every session is consistent, targeted, and effective. Most people see and feel results after their first few sessions, with the most significant changes appearing between weeks 4 and 6.
We start with our strongest spray — a concentrated blast of cold that penetrates deep into the fat layer. We work in small sections, 30 seconds at a time. The first few seconds feel genuinely cold, and then — almost immediately — most people feel little to no discomfort at all. Your skin goes numb quickly and the cold sensation fades. Think of it like jumping into a cold pool: shocking for a second, then you adjust.
💬 "Cold for a second, then you just don't feel it."Next comes the fog — a finer, more diffuse cold that spreads across the surface of the skin. This step builds collagen and tightens the skin as we go, which is how we avoid the loose skin that can come with other fat-loss methods. Same cold temperature as the spray, but it doesn't penetrate as deep — it's working the surface layer, keeping everything firm as the fat underneath recedes.
💬 "No loose skin — it tightens as it goes."The fat cells we've crystalized need to go somewhere — and that's your lymphatic system. We use a cryo-cooled lymphatic massager to manually push the treated fat through your lymphatic channels so your body can carry it away and convert it to energy. Most people describe this as feeling like cold butter — a smooth, firm, slightly cold pressure moving across the treated area. A lot of clients say this part is actually their favorite.
💬 "Feels like very cold butter — weirdly satisfying."The last step is the Power Plate — a vibration platform that rapidly contracts and releases your muscles (up to 50 times per second), which drives lymphatic drainage and flushes out anything the massage couldn't reach. 10–15 minutes on the Power Plate burns roughly the same calories as an hour-long walk, builds core strength, and locks in the work we just did. After this, you're done — total session time is about 30 minutes — and free to go about your day.
💬 "Like a full-body vibration — you feel it working."100% non-invasive. No injections, no chemicals, nothing foreign in your body.
Walk in, get treated, walk out. No redness, bruising, or recovery period.
Unlike GLP-1s, the fat doesn't creep back. Once the cells are gone, they're gone.
