Guide to Non-Surgical Skin Tightening. In general, non-surgical skin tightening procedures work by using targeted energy to heat deeper layers of skin, which stimulates collagen and elastin production and gradually improves skin tone and texture. Some treatments also affect fibrous tissue to help smooth cellulite.
There are plenty of topical products that promise to firm and tighten the appearance of neck skin, but when you want to see real change in the mirror, most experts agree that radio frequency (RF) energy is the best way to go. RF energy heats the collagen under the skin’s surface, causing it to contract and to also create more collagen naturally. Collagen is one of the building blocks of healthy, youthful skin that dwindles with advancing age.
