Advanced Treatments and Technologies
Superficial Radiotherapy (SRT)
Superficial Radiotherapy (SRT) is a low-energy radiotherapy that penetrates only a short distance below the skin's surface. It offers a highly effective, painless, and cosmetically favorable alternative to surgery for specific types of skin cancers and patient groups. The SRT - 100™ is the latest advancement in superficial radiotherapy, providing a painless experience similar to an X-ray.

EMSculpt NEO
EMSculpt NEO is a revolutionary body contouring device that simultaneously builds muscle and burns fat. It can be applied to various areas, including the abs, butt, thighs, calves, biceps, and triceps. Typically, four 30-minute weekly sessions result in a 30% reduction in fat, a 25% improvement in muscle toning, and a 19% improvement in abdominal separation, with an average loss of 5.9 centimeters around the waist.
