st-a hair removing system ⑴ treatment principle the system emits varied wavelength, intense pulse, and broad-spectrum light. it can permeate the cuticle to the derma and take effect on the abnormal pigment to break the abnormal pigment. highly controlled flashes of light are selectively absorbed by hair follicles. the absorbed light heats the hair, which damages or destroys the growing potential of the follicle, stimulates the proliferation of collagen and improving the rearrangement of elastic fibers, finally achieving the purpose of hair removal and skin rejuvenation. (2) features of the system 1. broad-spectrum, non-invasive photodynamic therapy 2. selective absorption: aiming at different symptoms 3. strong penetrating force: decomposing the deep pigment effectively 4. effectively filtering the harmful light with triple light filter systems 5. three cooling systems: built-in circle water-cooling system air cooling system semiconductor cooling device 6. silver catoptric system: remarkable optical effect 7. water-electricity separator inside: insuring the system safety 8. double counter system: insuring the quality 9. lcd screen with low failure rate 10. stainless water box: insuring continuously and well running for a long time 11. magnetic drive pump controlled water circulation: lower noise, longer lifetime 12. smaller handle with the same spot size 13. designed with automobile paint: showing the quality
