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. Auto-identified 5 handles for your choice VR(500nm-600nm): Remove vascular and improve face redness PR(550-650nm): Remove freckle, sunburn,age spots, acne scar and facial defects etc AR(420-520nm): lmprove acne, remove acne scar SR(560-950nm): Pore remover, skin whitening,skin tightening ,anti-puffi-ness ,dark circles etc HR（650nm-950nm): Permanent and Painless Hair removal. Remove un-wanted hair on full body Advantages of SPECTRUM DPL: 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.   DPL machine Specifications: WaveLength PR:550-650nmVR:500-600nm Optional:(HR:650-950nmSR:560-950nmAR420-520nm) Fluence 10-50J/cm2SHR:1-10J/cm2 Frequency 1-10HZ RFpower 1-30W InputPower 4000W PowerSource PureSapphire Lamp GermanImportedlamp SpotSize 10*40mmfor(SR,VR,AR,PR)15*50mmforHR Contactcoolingtemperature Max-10℃ CoolingSystem Builtinwatercooling+semiconductorcooling+aircooling LCDScreen 10.4inchtruecolortouchscreencontrol packagesize 82*59*122cm Weight 99kg   Treatment Procedure （1）All cosmetic treatment should be done before consultation, protection, camera, etc., patients need to have the right attitude toward the treatment （2）Cleaning the treatment area,  patients need to be off the jewelry （3）Taking a skin test before the treatment, choose the area without the effect on appearance, such as ears, apply the Cold gel on the testing skin , adjust the energy about 2-3 spots. After 3min, observe the treatment area, if there is redness, it is the suitable energy. （4）After skin test, apply the cold gel in the treatment area about, use the suitable energy to do treatment. Do not press the skin during the treatment. （5）Before the hair removal treatment, shave the hair until 1-2mm, the treatment process is same as above. （6）According to the normal physiological process, the interval time is 21 days. The whole treatment should be 3-5 times. Exhibition We have sold a lot of products to all over the world.
