RF devices provide RF energy, which does not scatter or get absorbed during the transmission through tissue. When compared to light and/or laser energies, RF can penetrate deep into dermis with minimal heat sensation on the surface. RF energy causes ionic agitation and increases the tissue temperature.
The boundaries of the treated tissue and its surrounding are obvious because of the highly precise nature of RF technology, which can be enhanced by electrode design, power setting, pulsing technique and pulse modification. RF energy causes the skin to shrink and contract when heated.
The most advanced RF-based systems have been designed for the treatments of various skin problems in dermatology and plastic surgery. They have been used to restructure the dermal collagen by transmitting heat created from RF energy to dermis. To avoid any epidermal damage, various skin cooling techniques have been applied. Non-ablative RF (NARF) is the term used for such method of RF base technology for skin rejuvenation and skin tightening goals.
SuperpulseRF™ is used for dermal skin heating with sparing of the epidermis due to the train of pulses with each pulse width shorter than skin thermal relaxation time. This will result in non- ablative skin tightening and lifting without the necessity of cryogen spray.
The technology works in two ways:
Heat generated by RF waves shinks the bundle of collagen under the skin. The collagen becomes shorter and the skin tightens.
The second phase begins as the body responds. The collagen will be gradually healed, renewed and even more collagen will be produced. The skin tightens and overall look is improved.
