Non-surgical body contouring is often advertised as if it could do almost anything. The reality is quieter: gradual, modest change in the firmness of skin or the tone of muscle, built over a course of treatment, in people who are well suited to it.
It is worth being precise about the words. Contouring is not weight loss. None of the treatments described here is designed to change your weight, and none is a substitute for diet, exercise or medical care. Most are tightening and toning treatments used on specific areas, and results vary from one person to the next.
Radiofrequency: tightening the skin
Radiofrequency devices warm the deeper layers of the skin to a controlled temperature. The heat causes existing collagen to contract and, over the following months, encourages new collagen to form. On the body, this is used where skin has softened or become crêpey: the abdomen, the upper arms, above the knees.
It comes in two broad forms. Non-invasive radiofrequency, such as Forma, is delivered through a handpiece glided over the skin, with little or no downtime. Radiofrequency microneedling, such as Morpheus8 Body, delivers energy through fine needles and reaches deeper, at the cost of a few days of redness and swelling. A systematic review of these devices found measurable improvement in skin laxity on the face and body, with mostly minor, temporary side effects. The change is real, but it is gradual.
Muscle stimulation: toning, not slimming
Electrical muscle stimulation, such as Evolve EMS, uses applicators on the skin to cause repeated, involuntary contractions of the muscle beneath. It is usually given as a course, with the aim of firmer, better-toned muscle in areas such as the abdomen, buttocks or thighs. It works alongside exercise, not instead of it.
The evidence here is still developing, and it is fair to say so. Much of the published research concerns a related technology, electromagnetic muscle stimulation. Most of those studies lacked a control group, and almost all were authored by advisers to the device manufacturer. Measured gains in abdominal muscle thickness have averaged around two millimetres, and one independent review described the evidence for efficacy as tenuous. For some people, a modest change is exactly what they want. For others, it won’t be enough, and that is better known before a course begins.
Injectable treatments for small areas
Injectable fat-reduction treatments work differently. A substance is injected into a small, well-defined pocket of fat, where it disrupts the fat cells, which the body then clears gradually over the following weeks. These are medical treatments. They require an in-person medical assessment, they are suited only to small, localised areas, and they are not a way to reduce your overall weight or to treat larger areas.
Swelling, tenderness, bruising and numbness in the treated area are common and usually temporary. The evidence varies considerably between products and between areas of the body, and some areas have been studied far less than others. Fat-dissolving injections offered without a medical assessment, or bought online, deserve real caution: unapproved products have been linked to scarring, infection and lasting skin damage.
Who these treatments suit
The people who tend to be well suited are already close to a weight they can maintain, with a specific concern in a specific area: skin that has lost firmness, muscle tone they would like to improve, or a small pocket of fat that has persisted despite a healthy routine. Results are gradual, they vary from person to person, and they are not permanent. Ageing continues, and changes in weight will change the treated area too.
These treatments are not suitable for everyone. Depending on the treatment, it is usually postponed or ruled out with:
- Pregnancy or breastfeeding
- A pacemaker or other implanted electronic device
- Metal implants in the area to be treated
- An active skin condition or infection in the area
Where skin is very loose, for example after significant weight loss, surgery may be the more appropriate route.
How we approach it at DROM
Every patient has an in-person consultation before any treatment, and with body treatments much of that conversation is about expectations. We look at the area, the quality of the skin and what you are hoping to see, and we will tell you plainly if a treatment is unlikely to deliver it. Sometimes the answer is a course of treatment. Sometimes it is a different approach entirely. Sometimes it is no treatment at all.
If you would like an honest view of what is realistic for you, you can book a consultation. It is a conversation, not a commitment.
Contouring concerns the firmness and shape of a specific area, not your weight, and that distinction should be clear before any course begins.
