Forma skin tightening treatment also relies on controlled radiofrequency energy to improve the appearance of the skin. During this treatment, the thermal energy permeates the upper layers of the skin without the risk of hot spots or discomfort. The Forma device has built-in temperature controls that prevent overheating without diminishing the desired effect within the layer of dermal tissue. During treatment, radiofrequency waves get absorbed into the dermis. The heating of dermal tissue prompts stimulation within the fibroblast cells that produce collagen, resulting in tighter, firmer, more youthful skin.
