that dermal fibroblasts produce a heat-shock response as a reaction to thermal injury18


. The result of this


response is the synthesis of heat shock proteins (hsp), such as hsp70,hsp47, and hsp27. Another effect that is attributed to treatment with RF is


an increase in the reaction rate of hormone-sensitive lipase (HSL), a key enzyme in the process of lipolysis. The breakdown of triglycerides into free fatty acids and glycerol by HSL causes a reduction in the volume of adipocytes. Fat tissue has greater resistance compared with the surrounding fibrous septa and for this reason, a greater amount of RF flow is critical for the transferal of energy through fat. The RF flow travels along the fibrous septa as the pathway of least resistance, causing the fibrous septa to absorb 1.4–3-times as much heat as fat. RF energy has emerged as the dominant non-invasive


procedure for skin tightening, body shaping and cellulite reduction. However, a major disadvantage of RF is patient discomfort, as well as side-effects such as blisters or burns when trying to reach the critical epidermal temperature required for clinical benefits. Although non- ablative RF treatments have been administered in aesthetic medicine for over a decade, issues of pain and safety have remained largely unresolved since the introduction of this technology to the aesthetic market. The aim of RF treatments is to produce bulk tissue heating, while leaving the epidermis unharmed. Uneven distribution of RF energy may contribute to the formation of Ôhot spotsÕ, with a higher density of RF energy on a small spot size. This, in turn, might cause discomfort or even pain to the patient, and may also increase the risk of side-effects such as first or second degree burns. In 2009, Venus Concept introduced the (MP)¨

technology that combines 3D bipolar RF and PEMF. The 3D bipolar RF supplies high-frequency alternating electrical currents that penetrate the skin and generate heat. The hand pieces of the (MP)¨ technology include an array of electrodes managed by a unique algorithm. The RF current is produced between any two electrodes in the array, creating a tightly-woven, uniform RF energy matrix. The rapidly oscillating array of bipolar RF energy creates an even, uniform heat pattern that quickly achieves the therapeutic temperature and sustains it comfortably. This allows for a pleasant, pain-free treatment, without any associated discomfort caused by RF focal Ôhot spotsÕ. The uniform heat pattern also provides an excellent safety profile and minimises the risk for any side-effects, making it possible to delegate the treatment.


Synergy of 3D bipolar RF and PEMF (MP)¨ comprises two independent technologies that work via different mechanisms. Bi-polar RF exerts its effect through a thermal mechanism, stimulating synthesis of collagen and elastic fibres via the induction of controlled thermal injury. PEMF is a non-thermal technology that triggers production of collagen fibres by direct stimulation of fibroblasts and promotion of fibroblast proliferation.
