Pure Impact™ by Sofwave Harley Street, London

Pure Impact is used to enhance deep muscle tone in:

• The abdomen, improving core stability and structure
• The glutes, lifting the posterior chain and restoring support
• The thighs, strengthening the quadriceps and hamstrings
• The upper arms, helping to maintain tone and shape

These areas are commonly affected by muscle loss due to ageing, hormonal change, pregnancy, inactivity, or weight fluctuation. The treatment can support visible contour improvement, but more importantly, it helps restore the muscular foundation beneath.

Pure Impact uses electrical muscle stimulation and Sofwave’s Plyopulse technology to induce supramaximal muscle contractions. These are deep, involuntary contractions that go beyond what is possible through voluntary movement, engaging both fast- and slow-twitch fibres.

Each 30-minute session delivers thousands of contractions in the targeted muscle group. This stimulation promotes increased muscle fibre density, improved neuromuscular control, and enhanced physical capacity. Most patients begin with a course of four sessions over two weeks, with visible results continuing to develop over several weeks.

There is no downtime, no discomfort, and no impact on skin colour or type.

Patients using GLP-1 medications
Weight loss medications such as Ozempic, Wegovy or Mounjaro (offered at Self London in our Self Structure GLP-1 programme) can lead to a reduction in lean muscle alongside fat loss. Pure Impact helps support core and glute strength during this transition, preventing loss of structure or tone.

Perimenopausal and postmenopausal women
Hormonal changes can result in rapid muscle decline, particularly in the posterior chain and core. This affects posture, energy, and shape. Pure Impact supports safe muscle restoration without joint loading or high-impact exercise.

Postnatal patients
Following pregnancy, many women find it difficult to reactivate deep core and glute muscles, even if they return to the gym. Pure Impact facilitates precise, symmetrical re-engagement — ideal for patients in early or late recovery.

Trainers, lifters and athletic patients
Even well-trained individuals sometimes struggle with gluteal or abdominal recruitment. Pure Impact helps improve fibre engagement and correct muscular asymmetries that may limit progress or affect performance. Those wishing to see more gains in the gym by building skeletal muscle mass will also benefit.

Those noticing body changes despite healthy weight
You may feel “softer” or less toned, even with no increase in fat. This is often due to muscle loss, not weight gain. Pure Impact can restore firmness by addressing the underlying structures that shape the body.

What should I expect during treatment?

No preparation is required in advance of a Pure Impact session. Each treatment lasts approximately 30 minutes. You will feel deep, rhythmic contractions in the treated area, strong but not painful. Most patients describe it as intense but satisfying.

Sessions are performed by our senior laser therapist, who is also a qualified personal trainer. Treatments are tailored according to your training history, postural needs, and muscle baseline. The technology is safe for all skin tones and there is no surface impact.

Patients return to work, training or movement immediately after.

You may begin to feel increased firmness or activation by the second session. Most patients notice visible changes within two to four weeks of completing a four-session course.

Results can be maintained through periodic top-up sessions, typically every one to two months, depending on age, activity level and hormonal stage.

Lean muscle is not just a fitness goal, it is a core part of how the body ages. Muscle supports the fascia and skin. It preserves volume and shape. It improves metabolic health, insulin sensitivity, bone density, and hormonal resilience.

From a structural ageing perspective, muscle is essential. Without it, the body loses definition, lift, and postural confidence, even in patients who remain slim. This is why traditional aesthetic strategies that focus only on fat or skin often fall short.

By restoring muscle tone in a targeted, safe and intelligent way, Pure Impact supports the visible body, but also the systems underneath. For patients navigating hormonal transition, recovering from illness or pregnancy, or simply wanting to feel strong again, it is a meaningful tool.

Pure Impact is fundamentally different from fat-focused or thermal contouring procedures.

Fat-freezing devices aim to reduce adipose volume by targeting fat cells, but they do not build or support muscle and can occasionally result in contour irregularities. Radiofrequency or thermal body treatments may temporarily tighten skin or stimulate collagen, but they do not strengthen the deeper muscle groups that define body shape or improve function. Surface-level EMS devices often lack the power to achieve supramaximal contraction or reach deep fibres.

Pure Impact delivers precise, symmetrical stimulation at high intensity without heating, surface contact risk, or skin tone limitations. By focusing on muscle, Pure Impact supports long-term structure. It enhances both function and appearance in a way that aligns with how the body truly ages, not just how it looks in stillness.

Yes. Many patients incorporate Pure Impact alongside resistance or performance training. It can help overcome plateaus, improve fibre activation, and support specific regions (glutes, core) that are not responding as expected.

Yes. Pure Impact uses electromagnetic energy, not heat or light. There is no interaction with melanin, and no risk of pigmentary change. It is suitable for all skin tones and types.

Pure Impact is not a fat reduction device. However, improved muscle tone can create a firmer, more lifted appearance, especially in the glutes, core or upper arms.

Most patients start with four sessions in two weeks. Maintenance varies: active patients may opt for monthly top-ups, while others repeat the full course quarterly or seasonally.

Some patients feel mild post-treatment soreness, similar to a good workout. It is not painful, and does not interfere with activity or recovery.

At Self London, we do not offer technologies unless they are clinically justified. Pure Impact has been introduced not as a trend, but as part of our structural philosophy: restoring muscle to support posture, lift, and confidence from within.

All treatments are delivered by a therapist trained both in device protocols and functional anatomy. Consultations are medically supervised. Your programme will be guided by clinical insight, not commercial targets.

We see Pure Impact as part of a larger system, not a standalone procedure – a meaningful intervention within aesthetic ageing, hormonal care, and long-term strength.
