Intense pulsed light is a technology harnessing specific light wave energy to treat and enhance the skin. Its principle is founded on the interaction between light and tissue, operating through the following mechanisms:
- Light Absorption: DPL devices emit light energy within specific wavelengths. This light is absorbed by pigments in the skin, such as melanin, or by hemoglobin in blood vessels. Once absorbed, the light energy is transformed into heat energy, which then inflicts thermal damage on the tissue.
- Thermal Damage and Regeneration: The thermal damage induced by the heat energy triggers the growth and repair mechanisms of the skin tissue. This process aids in eliminating hyperpigmentation, acne scars, and other skin tone – unevenness issues from the skin’s surface.
- Stimulates Collagen Synthesis: The heat generated by DPL within the skin also spurs collagen synthesis. Collagen, being the primary structural protein of the skin, its synthesis contributes to enhancing the skin’s elasticity and firmness.
