O Revitalift<\/strong>, a complete and comprehensive microneedle bipolar radiofrequency platform, joins the Visalift<\/strong>, microfocused ultrasound\u2014a service the company already offers\u2014expanding the range of solutions for treating the signs of aging.<\/p>\n

Comparing the Equipment<\/h2>\n

O Visalift<\/strong> It is a complete and comprehensive micro-focused ultrasound device. It has three pen-shaped tips for use on the face and, in addition, two others designed for use on the body. It works by creating micro-coagulation points beneath the skin\u2019s surface, at depths ranging from 1.5 mm to 4.5 mm (for the face) and from 8 mm to 13 mm (for body treatments). It works by stimulating collagen synthesis and reorganizing existing collagen (when applied at shallower or intermediate depths) or by causing a contraction in the SMAS\u2014the tissue between the subcutaneous fat and the muscles (when the energy is directed deeper).<\/p>\n

\u201cThe Revitalift<\/strong>, \u201d, which, in turn, uses needles to micro-perforate the skin while simultaneously stimulating it with radiofrequency, which causes controlled thermal damage,\u201d,<\/em> explains biomedical scientist Isabel Garcia, a speaker and scientific consultant at Pharmaesthetics.<\/p>\n

The needles themselves, which are coated with 24-karat gold, act as energy conductors. The cartridges have 10, 25, or 36 needles arranged in rows, meaning they can cover smaller or larger areas, depending on the number of needles. In addition, you can choose between insulated and non-insulated types. The difference? When the cartridge is insulated, the radiofrequency is concentrated at the tip of the needle.<\/p>\n

If it is the non-insulated type, this means that the energy travels through the entire needle\u2014that is, it stimulates the skin from the epidermis to the dermis.<\/p>\n

The depth reached by the needle\u2014and, consequently, by the radiofrequency\u2014is determined by the settings adjusted before treatment, ranging from 0.5 mm to 3.5 mm. It is this choice, as well as the selection of the cartridge type\u2014insulated or non-insulated\u2014that will determine how the technology works. \u201cWhen, for example, a non-insulated cartridge is used at a shallower depth, it causes a more superficial thermal lesion,\u201d explains Isabel Garcia. \u201cChoosing an insulated cartridge combined with a greater depth directs the radiofrequency action solely to the dermis, without causing any type of ablation,\u201d adds the biomedical scientist. In summary, there are a variety of protocol options.<\/p>\n

It\u2019s worth noting that the Revitalift platform also features a cryoanesthesia tip, which desensitizes the treatment area and makes the procedure more comfortable. Another unique feature that helps minimize discomfort is the suction created by the radiofrequency tip itself\u2014it stabilizes the skin, tightening it and facilitating application.<\/p>\n
