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...
