Mechanism of Action
The 980 diode laser converts light to heat delivered through an optical fiber. Heat is absorbed by the tissue in the target area. This leads to thermal chemical denaturization of the tissue composition and destruction of the fat cells without damaging the surrounding tissue (depth of penetration in fat is 2-3 mm). The procedure also causes simultaneous collagen stimulation for skin tightening and contouring.
Thermal energy rising in the dermis leads to:
- Stimulation of fibroblasts
- Production of collagen
- Tightening of tissue
The adipose tissue concentrates the thermal effect caused by the laser due to its high absorption coefficient.
