CoolTone is a noninvasive body contouring treatment that was FDA-cleared in June 2019 to strengthen and tone muscles in the thighs, butt, and abdomen.
The CoolTone device, manufactured by Allergan and used for years in rehabilitation therapy, uses magnetic muscle stimulation (MMS) to pass electromagnetic energy into your muscles in order to stimulate contractions, creating a stronger, more toned physique.Â
Muscle-building CoolTone complements CoolSculptingâs noninvasive body contouring and fat reduction. The two treatments can even be done on the same day, for optimal results.
As part of a healthy lifestyle, CoolTone treatments can create muscle definition beyond what you can achieve with exercise alone, creating a more toned and defined appearance.Â
âItâs able to contract close to 100% of the targeted muscles,â says Dr. Janet Allenby, a dermatologist in Delray Beach, Florida.â This is a huge jump from the 30-40% engagement you generally achieve during a gym workout, and itâs why youâll see better results in a short amount of time.âÂ
Stimulating your muscles at such a high levelânearly 25,000 times in one 30-minute sessionâmay sound painful, but thereâs surprisingly little discomfort during and after a treatment.
According to Dr. Allenby, people who are close to ideal body weight, shape, and musculature will likely see the most rapid changes.
The full body-sculpting benefits of CoolTone can take four to six weeks after a series of treatment sessions to appear, but you should feel stronger within a few weeks of a single treatment.
âThe first time I went swimming after a treatment, I felt like Superwoman,â says Dr. Allenby. âThe strength you feel is really amazing.â Â
RealSelf Tip: CoolTone can also help reduce diastasis recti, a condition common after pregnancy in which the abdominal muscles (the rectus abdominis muscles) separate, making your abdomen protrude. âBy strengthening these muscles, we see a huge improvement with âmommy belly,ââ says Dr. Allenby.
Pros
Cons
An initial series of at least four treatments is recommended. Many providers offer a package of four treatments at a reduced rate.
The CoolTone photos in our gallery have been shared by the provider who performed the procedure, with the patient's consent.
Ideal candidates for CoolTone are at or near their goal weight, without a lot of excess fat that might prevent the magnetic energy from reaching the muscle. According to Dr. Allenby, âif there is a greater than 8cm fat padding, it is more limited in hitting the targeted muscle.â
âItâs not that I wouldnât treat someone with more padding,â she explains. âTheyâll have a response, itâs just that it will take more treatment cycles than [for] someone whoâs in the ideal parameters.âÂ
Some people arenât well-suited for CoolTone treatment. This includes those who suffer from certain conditions (including seizure disorders and GI disorders like IBS) and those with metal or electronic implants, such as cardiac pacemakers, metal IUDs, cochlear implants, and hearing aids.Â
Women may find that their period comes sooner or cramping is increased or intensified after a CoolTone treatment, so itâs recommended not to undergo treatment in the week prior to menstruation.
Youâre never going to be able to achieve these results in the gym. It augments what youâre already doing and assists you in getting better at the things you want to do physically.ââDr. Janet Allenby, Delray Beach, Florida, dermatologist
You'll lie on a table, and your provider will place a paddle-like applicator on your stomach, thighs, or buttocks.
Once it's turned on, the device passes magnetic energy, bypassing your skin and fat to target the muscle layer, where it induces thousands of involuntary muscle contractions.
The intensity can be as light as you want, but a moderate to high level is recommended for better results. âWe want to get to the intensity where people are just below the point of being uncomfortable,â says Dr. Allenby. Â
Surprisingly, âIf you have someone whoâs more out of shape, you can go at 100% and they wonât be uncomfortable, because they donât have as much muscle mass,â says Dr. Allenby. âIf someone is more muscular, you have to go lower or itâs uncomfortable.â Â
You can feel your muscles contracting as the device stimulates them. This can feel strange, but you can relax otherwise.
âItâs a very passive treatment. Most people watch TV during it or check their email,â says Dr. Allenby.Â
Each treatment lasts 20-30 minutes, andâthough thereâs no published research yet outlining what kind of treatment protocol works best for CoolToneâdoctors recommend an initial series of four to six treatments over the course of two weeks.
Smaller muscle masses like thighs get a 20-minute treatment, while a larger muscle mass, abs, and glutes get a 30-minute treatment.
Thereâs no downtime afterward, so youâll be free to resume your everyday activities.Â
Side effects are minimal. You may feel some soreness in the treated area, like youâve had an intense workout. Any soreness should be very manageable and last only for a day or two. âItâs not like when you do squats for the first time and canât sit down for a week,â says Dr. Allenby.Â
Thereâs no specific post-treatment protocol, Dr. Allenby says. âWe do encourage our patients to continue a healthy lifestyle. Regular exercise and healthy eating will only enhance your results and help you maintain them for a longer period of time.â
Most providers recommend an initial treatment plan of four to six sessions, two to three days apart, for best results.
Some people see (or feel) results after one treatment session. Your results will improve with each session and for about six weeks afterward, as the targeted muscle fibers strengthen and muscle mass increases.
With a healthy diet and regular exercise (which will be easier to do, since youâll be stronger), results can last up to six months for some people. After that, follow-up treatments are recommended to maintain them. Â
The most effective schedule for follow-up treatments is still being determined. Some doctors recommend a maintenance treatment every three to six months. Dr. Allenby says sessions every four to six weeks can maintain results very nicely.Â
One RealSelf member had six sessions that left his six-pack much more defined. Another RealSelf member, who had her inner thighs treated, says she saw a definite but subtle difference. âMy inner thighs arenât as saggy-looking. Itâs about a 50% improvement, but Iâll take it.âÂ
After treatment in the abdominal area, some patients have even experienced less back pain. âWhat really surprised me is the significant relief of back pain from having my core strengthened,â says one RealSelf member. âMy posture has dramatically improved, and the change in muscle tone in the treatment areas is significant. The pain relief was just a big bonus!â
âYou donât build muscle overnight, but this is as close to overnight as you can get! Three weeks after my last treatment, Iâm still seeing the results getting better.ââGenius844748, RealSelf member
Not really. TENS (transcutaneous electrical nerve stimulation) units send an electrical impulse through the skin, but they would have to be set to very uncomfortable levels to be able to penetrate the muscle. âThe skin would feel like itâs being burned,â says Dr. Allenby. This is why TENS units havenât been successful in treating muscles and work better for treating pain.Â
CoolTone bypasses the skin completely and focuses solely on the muscle. âThis is why we can achieve those intense contractions while patients are in a comfortable passive state,â explains Dr. Allenby.
The primary alternative to CoolTone is Emsculpt, which uses high-intensity focused electromagnetic energy to stimulate muscle contractions, toning muscles while burning fat.
Emsculpt can treat the same body areas as CoolTone, plus the arms and calves with their newest handpieces. A series of four 30-minute treatments is recommended. Â
The manufacturer of CoolTone says that its device has â50% more magnetic intensity,â but that claim has not yet been clinically established. Dr. Eugene Nowak, a dermatologic surgeon in Chula Vista, California, says âThereâs no study to show that this increase provides additional benefit.â
The new Emsculpt NEO, launched in fall 2020, offers enhanced HIFEM technology that delivers up to 20% more electromagnetic pulses than the original. It combines muscle toning with radiofrequency (RF) energy in the form of heat, to burn fat (an optional feature for areas like the butt, where some patients like to keep that volume).Â
As mentioned above, RealSelf members give Emsculpt a significantly higher Worth It Rating than CoolTone (87% vs. 50%, respectively).Â

CoolTone works by activating the muscle layer, whereas a CoolSculpting treatment targets the fat cells.Â
"CoolScuplting is an FDA-approved treatment that eliminates stubborn fat through a cooling technology," says Boca Raton, FL plastic surgeon Dr. Scott Farber in a RealSelf Q&A. "CoolTone targets muscle by strengthening, toning and firming the abdomen, buttock, and thighs through Magnetic Muscle Stimulation technology. A combination of these treatments often delivers optimal aesthetic results."
Unlike the high-intensity focused electromagnetic energy (HIFEM) used by EmSculpt, CoolTone's MMS technology does not burn fat.Â
A recent study in Lasers in Surgery & Medicine found that MMS "failed to demonstrate either fat cell injury or inflammatory response."
