The main goal of radiofrequency skin rejuvenation is to stimulate collagen production
deep within the skin (the dermis and cutaneous layers) while leaving
the skin's surface (the epidemis) relatively untouched. Collagen fibers
are essential for firm, youthful-looking skin, but they tend to
degenerate as we age, mainly because of overexposure to the sun.
In addition to stimulating new collagen, radiofrequency treatment also causes some contraction of the skin, thus tightening it. Although
you'll notice the treatment's tightening effects immediately, the more
significant improvements will occur gradually over a period of several
weeks or months as the new collagen forms.
