Skin laxity or loose skin, is frequent in younger people after weight loss or pregnancy and in older age due to diminished collagen production and function. The Journal of Cosmetic Dermatology discusses how basic science illustrates that both skin laxity and cellulite are related to the loss in quantity and function of dermal collagen fibres, the main structural protein component of connective tissue.
The field of body contouring and skin tightening has grown very rapidly over the past several years, with many new devices appearing on the market that utilise radiofrequency (RF) energy to effectively tighten and rejuvenate the skin. What originally began with a single monopolar RF device has progressed into a world in which there are skin-tightening devices that utilize, besides monopolar and bipolar RF energy, tripolar RF energy. Each of these devices has proven positive effects on the skin, which can lead to skin tightening and ultimate rejuvenation of the skin.
The effects of radiofrequency treatments are mostly attributable to the heat that is generated by the RF waves. During treatment, the RF waves penetrate the skin to tighten it from the inside out, as they stimulate collagen fibroblast production, which in turn trigger the production of fresh collagen fibres resulting in tighter, more taut skin which is demonstrably younger.
Since RF energy produces an electrical current instead of a light source, RF energies can be used for patients of all skin types – that is, it is colour blind and allows for different depths of penetration based on what is to be treated, allowing for ultimate collagen contraction and production of new collagen.
RF procedures are safe, gentle and effective, resulting in healthier, younger- looking skin. They are highly popular as there is no pain associated with the treatments and no downtime is necessary.
