DPL equipment combines intense pulsed light (IPL) and laser technology to solve various skin problems. It promotes the proliferation of internal collagen and elasticity, reduces wrinkles, and removes pigmentation through photothermal action.

The high energy generated by the laser and the focused and precise monochromatic light have strong penetrating power and targeting property. Using the selective photothermal absorption principle of laser irradiation, that is, the high energy emitted by the laser instantaneously penetrates the skin to reach the deep pigment clusters in a short period of time, and is selectively absorbed by the corresponding pigment clusters. The pigment clusters expand and fragment rapidly due to heat, and after fragmentation, they are metabolized and eliminated from the body. The pigment gradually fades until it disappears.
