What is the main difference between EMSCULPT and CoolSculpting?

They solve two different problems. EMSCULPT builds muscle and reduces fat using HIFEM electromagnetic energy, which triggers thousands of supramaximal muscle contractions in a single session — far more intense than voluntary exercise. CoolSculpting reduces fat only, using cryolipolysis (controlled cooling) to freeze and permanently destroy fat cells in a targeted area. In short: EMSCULPT tones and strengthens muscle while burning some fat; CoolSculpting purely removes stubborn fat.

Which one should I choose — build muscle or freeze fat?

If your goal is more definition, tone, and a stronger core or lifted buttocks, EMSCULPT is the better fit because it builds muscle that diet and exercise struggle to target. If your concern is a distinct pocket of stubborn fat — a lower-belly bulge, flanks, or a double chin — that won't budge despite a healthy lifestyle, CoolSculpting directly removes that fat. Many patients who want both fat reduction and definition combine the two.

Are the results permanent?

CoolSculpting permanently destroys the treated fat cells, and they do not return — though remaining fat cells can still enlarge with significant weight gain, so a stable weight maintains the result. EMSCULPT builds muscle, and like any muscle, it needs to be maintained; results last several months and are sustained with periodic maintenance sessions and an active lifestyle. Your practitioner will recommend a maintenance plan suited to your goals.

How many sessions does each treatment need?

EMSCULPT is typically a course of four sessions over two weeks (two per week), with results developing over the following weeks. CoolSculpting often requires one to three sessions per area depending on the amount of fat and your goals, with results appearing gradually over 1–3 months as the body clears the destroyed fat cells. We'll map out the right number of sessions at your consultation.

Is either treatment painful, and is there downtime?

Both are non-invasive with no required downtime. EMSCULPT feels like an intense workout — strong but tolerable muscle contractions — and you may feel like you've exercised afterward. CoolSculpting begins with intense cold and a pulling/suction sensation that numbs within minutes; afterward the area may be red, swollen, tender, or temporarily numb for a few days to weeks. Most patients return to normal activities straight away.

What areas can each treatment target?

EMSCULPT is most popular for the abdomen and buttocks, and can also treat the arms, thighs, and calves to build and tone muscle. CoolSculpting targets pockets of fat in areas such as the abdomen, flanks (love handles), back, inner and outer thighs, upper arms, and under the chin. Your suitability for each area is assessed during consultation.

Can I combine EMSCULPT and CoolSculpting?

Yes — combining them is a popular strategy because they address body shape from two angles. A common approach is CoolSculpting first to remove a stubborn fat pocket, followed by EMSCULPT to build and define the muscle underneath. Because one removes fat and the other builds muscle, they complement rather than overlap. Your practitioner will sequence the treatments to suit your goals.

Will either treatment help me lose weight?

Neither is a weight-loss treatment, and neither replaces diet and exercise. CoolSculpting reduces stubborn fat in a specific area to improve contour; EMSCULPT builds muscle and improves tone. Both work best for people who are already near their goal weight and want to refine specific areas that haven't responded to a healthy lifestyle.

How much do EMSCULPT and CoolSculpting cost at 99 Medispa?

Pricing depends on the area treated and the number of sessions in your plan. We offer both treatments at our Sydney CBD clinic at 99 York St and can recommend the most cost-effective approach — whether that's one treatment or a combination — at your consultation.

EMSCULPT vs CoolSculpting

Build Muscle or Freeze Fat?

Both refine the body without surgery — but they do opposite jobs. One builds and tones muscle, the other permanently removes stubborn fat.

Treatment Overview

Two Body-Contouring Treatments, Two Different Jobs

If you're researching non-surgical body contouring in Sydney, two names dominate the conversation: EMSCULPT and CoolSculpting. Both are non-invasive, require no incisions or anaesthesia, and are designed for people near their goal weight who want to refine a specific area. But they are not interchangeable — they target different tissue entirely.

EMSCULPT uses HIFEM (high-intensity focused electromagnetic) energy to trigger supramaximal muscle contractions — thousands in a single session, beyond what you could achieve voluntarily. This builds and tones muscle and reduces fat in the treated area. CoolSculpting uses cryolipolysis — precisely controlled cooling that crystallises and permanently destroys fat cells, which the body then clears naturally over the following weeks.

At 99 Medispa, we offer both at our Sydney CBD clinic. That means your practitioner can assess your body, your muscle tone, and your fat distribution, and recommend the treatment — or the combination — that actually matches your goal, rather than fitting your goal to the one device they happen to own.

Muscle Building

How EMSCULPT Works

EMSCULPT places an applicator over the target area — most often the abdomen or buttocks — and delivers high-intensity focused electromagnetic (HIFEM) energy. This bypasses the brain's normal limits on muscle exertion, producing supramaximal contractions: tens of thousands of them in a 30-minute session.

These contractions force the muscle to adapt, building density and tone that voluntary exercise struggles to achieve. The intense metabolic demand also prompts fat cells in the area to break down, so EMSCULPT delivers both muscle growth and fat reduction in the treated zone.

EMSCULPT is delivered as a short course, and results develop over the following weeks as the muscle strengthens. It's ideal for definition and tone rather than removing large fat deposits.

Best for: Building core or buttock definition, improving muscle tone, patients near goal weight who want a stronger, more sculpted shape.

Fat Freezing

How CoolSculpting Works

CoolSculpting uses cryolipolysis — the science that fat cells are more vulnerable to cold than surrounding tissue. An applicator draws the target area in and chills it to a precise temperature that crystallises the fat cells without harming the skin, nerves, or muscle.

Once frozen, the damaged fat cells die and are gradually cleared by the body's lymphatic system over the following weeks. Because the cells are permanently removed, they cannot return — the contour improvement is lasting, provided you maintain a stable weight.

Results appear gradually over 1–3 months. CoolSculpting is purely a fat-reduction treatment — it does not build muscle or tighten skin — so it's ideal for distinct, stubborn pockets of fat.

Best for: Stubborn fat pockets that resist diet and exercise — lower belly, flanks, back, thighs, upper arms, double chin.

What Each Treatment Targets

Muscle Tone vs Fat Pockets, Side by Side

The simplest way to choose is to picture the change you want. EMSCULPT strengthens and defines the muscle layer; CoolSculpting removes the fat layer sitting above it.

Decision Guide

Which Treatment Is Right for You?

The best choice comes down to whether you want to add muscle or remove fat. Here's a practical guide:

Choose EMSCULPT If:

You want more muscle definition and tone, not just fat loss
You'd like a stronger core or a lifted, firmer buttock
You're already close to your goal weight and exercise regularly
Your problem area is a lack of tone rather than a fat bulge
You want to enhance results you've worked for at the gym
You're comfortable with a short course of four sessions

Choose CoolSculpting If:

You have a distinct, stubborn pocket of fat that won't shift
Your concern is a lower-belly bulge, flanks, or a double chin
You want permanent removal of fat cells in a specific area
You're near your goal weight but a particular area resists exercise
Muscle tone isn't your concern — you want a smoother contour
You prefer a treatment you can largely set and relax through

The combination approach: Many patients use both — CoolSculpting to remove a stubborn fat pocket, then EMSCULPT to build and define the muscle beneath. Because one removes fat and the other builds muscle, they work together for a more complete transformation than either delivers alone. At 99 Medispa, we have both in our Sydney CBD clinic, so you can plan the combination in one place.
