As we get older, the normal aging process causes a loss of the underlying deep support structures made from collagen and elastin in our skin. Repetitive facial expressions lead to the deepening of lines and wrinkles. When we add sun exposure into the mix, photoaging plus natural aging leads to loose, sagging skin, uneven texture, large visible pores, and other concerns.
How Does RF Microneedling Work?
Advanced cosmetic skin treatments all share one feature in common: controlled skin injury that stimulates your body’s own wound healing response to generate fresh collagen, new skin cells, and restored skin architecture. Using a specialized handpiece, a stamp-sized tool equipped with a grid of tiny needles is introduced through the epidermis, into the dermis, at a precisely controlled depth.
Radiofrequency energy, which has been used in various medical applications for over 75 years (and for cosmetic use since 2002), is simply a combination of electrical energy and a magnetic field that got its name because the frequency of the waves looks similar to radio waves. The column of tissue where each micro-puncture and RF energy delivery happens is called the RF thermal zone (RTZ).
These channels become the centers for a remarkable wound healing response, where the skin structure is rebuilt and new collagen and elastin form over the next few months. Skin tightening occurs when collagen contracts in response to being exposed to heat. Skin rejuvenation occurs from a combination of new collagen, new elastin, the spurring of new cell growth from wound healing, and new hyaluronic acid formation.
