working principle DPL's unique narrow-band light of 550-650nm can produce photothermal and photochemical effects at the same time. The photothermal effect causes part of the dermis to age and heat coagulation of the naive collagen, so that the activity of fibroblasts promotes the regeneration of subcutaneous collagen. Photochemical action rearranges the deep collagen fibers and elastic fibers, restores skin elasticity, and at the same time enhances the function of blood vessel tissues, enhances skin metabolism, makes the skin moist, delicate and elastic, and achieves a precise skin rejuvenation effect. Function: HR:Permanent hair removal SR: skin rejuvenation : skin whitening,  tightening pores, improving skin texture, and enhancing skin elasticity AR: acne mark, acne removal PR: pigment removal : freckles ,age spots , sun spots and so on. VR: vascular removal , vein removal , redness Advantages: 1. Narrowband 100nm precision pulsed light technology: quickly and effectively solve the problem of facial freckles and telangiectasia (red face). 2. Germany Heraeus imported xenon lamp: the xenon lamp is the core of the machine. It adopts German original imported xenon lamp, has a number of global patented technologies, and emits light 1 million times. 3. OPT power supply: the energy is uniform and stable, which not only improves the comfort of treatment, but also maintains high energy. 4. Five kinds of hand tools for different diseases: five handles for your choice, HR, SR, PR, VR, AR. 5. Sliding treatment technology: the highest frequency is 10hz in fast mode, which speeds up the operation and shortens the treatment time.
