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. Indications Freckle removal: freckles, spotted age spots, etc. DPL precise skin rejuvenation: whitening and rejuvenating skin, tightening pores, improving skin texture, and enhancing skin elasticity Acne: improve acne, improve local inflammation and redness Red blood streaks: red blood streaks caused by facial flushing and capillary dilation Hair removal: including front and back hairline, face, lip hair, neck, arms, hands, body, bikini, legs, feet 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. Narrow-spectrum 100nm delicate pulse light technology. Quickly and efficiently solve the facial freckles and telangiectasia (red face) problems. 2. Core of Light Imported from Germany. Xenon lamp is the core of energy. The light adopts German original im-ported xenon lamp which has obtained many patented technologies  around the world, and the minimum effective light emission is 1,000,000  times. 3. OPT power supply. the energy is uniform and stable, which not only improves the comfort treatment feeling, but also maintains the high energy. 4.Multiple wavelengths available for use on all skins. Five handles for your choice, HR, SR, PR, VR, AR. 5. In-motion technology. Fast mode with 10hz high frequency, which speeds up the operation and reduces 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   Exhibition We have sold a lot of products to all over the world.
