Combination colours are a synergetic "light digestion + light bursting" synergetic, synchronizing light and dark spots and improving skin appearances. (b) at the time of the visit, colour light was activated on some light skin colours and on smaller molecules, allowing them to be softly decompositioned and digested to reduce light skin colours; the lasers then act on dark and larger molecules, using the high energy of the laser instantaneous blasting the rigid pigment into tiny color molecules, and metabolize them out of the body, thus removing the dark spots and allowing them to be more thorough, clean and comprehensive. Combination light can filter out those wavelengths that do not have a visiting function and are likely to cause discomfort, leaving only those parts of the spectrum that are relevant to the visit. In this way, the accumulation of skin heat from the luminous skins in the past was avoided, the heat of the consultations was reduced or waived, and the need to apply the same cooling formula after the visits was made. At the same time, the "selected" spectra suitable for consultation, which is accurate and optimized, allows energy to be more concentrated and more accurately penetrating into the depths of the skin, so that it can easily have beautiful skin and solve various skin problems. Advantage 1, composite colour technology, which combines four photons and two lasers, not only has the full advantages of traditional light, but also incorporates the essence of modern high-tech elements, such as the use of composite colour technology, combining photons and laser synergies to achieve a holistic view of the face, and to improve the limitations of previous partial visits, making the perception more comprehensive and thorough. 2. Combination colours use non-involved non-involved therapy, low-energy and softer wide-spectral power, an abnormally vascular chromosomal base that directly affects the skin, fully stimulates the regeneration of gelatine proteins, restores skin elasticity, and feels more quickly and visible. 3. The composite colour-based system is a relatively new technology developed jointly for the special skin of asians, with four photons and two well-integrated multi-purpose colour-based workstations. 4. Non-traumatized skin technologies. 5. All-faced visits; breaking the limitations of the past of only cooking can make beauty feel everywhere. There is no need for leave; after a visit, there is only a slight red swollen feeling, and there is no other discomfort. 7. Multiple skin problems can be improved at the same time during a single course of treatment, which can remove or diminish various colours and geriatric spots; excretion of hairy cheeks and red-coloured slag noses; and constriction of large hair holes. It can significantly improve rough skin on the face; it can reduce the red mark of haemorrhoids; it can reduce mild haemorrhoids; it can improve the physical and elasticity of the skin so that the skin is thin and very flexible; it can also remove extra hair on the face。
