The theoretical basis for laser treatment of skin pigmentation and laser beauty is the “selective photothermolysis” theory proposed by Dr. Anderson RR. and Parrish JA. in the United States in 1983.
Selective photothermolysis is the selective absorption of laser energy by certain specific tissue components, and the heat generated by thermal effects destroys these specific tissue components.
The body’s own immune and metabolic systems can absorb and eliminate these damaged tissue debris to achieve the goal of treating pigmented diseases. Instantly emit laser energy to efficiently crush the chromophore of the diseased tissue.
A part of the (epidermal) chromophore is fragmented and excreted from the epidermis. A part of the chromophore (under the epidermis) is broken into small particles that can be engulfed by macrophages.
After phagocyte digestion, it is finally excreted through the lymphatic circulation, and the chromophore of the diseased tissue will gradually decrease until it disappears, while the surrounding normal tissue is not damaged.
