The market is now a lot of beauty hospitals, publicity is more exaggerated, list, there are so many common: 532 laser, the scientific name is also called KTP laser, 532 refers specifically to the wavelength, there are millisecond and nanosecond two, millisecond 532 laser commonly used to do the treatment of red blood, but now this kind of machine is not much, rare; nanosecond is generally used to do to do a variety of pigmentation, the effect is good, but also high risk. 585/595 laser, also known as dye laser, recognized as the gold standard of vascular treatment, safe and effective, but to pursue the best results, the treatment will leave purpura, usually about a week to fade. 694 laser, also known as ruby laser, is relatively rare, generally marketed with nanosecond level for clinical use, requires extremely experienced doctors to use it well, mainly also used to treat pigmentation slightly to do a little fierce, often occurring skin pigmentation loss, after doing the spot is gone, the skin is also whiter than the surrounding, incongruous. 755 laser, some people call it emerald, some people call it purple emerald, in fact, are the same thing, this laser is currently not produced domestically, expensive, but, very suitable for yellow people. Millisecond can be used for hair removal, or do to do whitening; nanosecond can do pigmentation. Semiconductor laser, wavelength 810nm, the development of semiconductor technology is really worship, if one day other wavelengths of semiconductor laser to do, the current market structure is estimated to be rewritten, but has not seen any obvious signs. This laser is generally used for hair removal, the production threshold is not high, there are several foreign production, the domestic use of many. 1064 laser, the name is extremely tongue-twisting, the scientific name is neodymium-doped aluminum garnet, every time you read it, your tongue will roll up, a jack-of-all-trades type product, suitable for all kinds of treatment, from hair removal to pigmentation to skin rejuvenation, can find its figure, but are not the first choice. The unbeatable 1064 has also derived wavelengths like 1440 and 1320, which are now often used for skin rejuvenation and wrinkle removal. Copper vapor laser, almost extinct in the market, there may be domestic manufacturers to produce, the original used to do hemangioma and other disease treatment, side effects are too big. The actual light, or color light, is not a laser, simply put, is a senior flash, early laser production technology is limited, the cost is too high, so out of such a compromise product, now also used to do to do skin rejuvenation, other treatment with less, do freckles is not bad, but the recurrence is relatively fast.
