What is the difference between 808nm hair removal and opt hair removal?

808 Semiconductor Laser Hair Removal: Based on the principle of selective photothermal action, hair follicles and hair shafts are rich in melanin. The wavelength of 808 nm laser can target melanin accurately and selectively for hair removal treatment, not only for black hair, but also for other color hair. , Yellow hair, white hair, brown hair can be removed efficiently, stable performance, accurate and fast, melanin adsorption effect is very good.
opt Laser Hair Removal: The selected laser wavelength is relatively broad, and it has a good effect on black hair, but it has a weak effect on hair of other colors, such as yellow hair and white fluff, and has a slight tingling sensation. 808 semiconductor laser hair removal is the use of semiconductor laser, can only be used for hair removal treatment, more professional, opt is the use of strong pulsed light plus radio frequency technology, dual wavelength cut-off technology, in addition to hair removal can also be used for whole face rejuvenation facial pigment Treatment of sexual lesions (freckles, sun spots, age spots) and acne scars, the effect is significant.

The abbreviation of IPL Intense Pulse Light, now also refers to the intense pulse light equipment. OPT Optimal Pulse Technology (OPT ™) is the abbreviation of two different categories of concepts. They claim that the IPL they produce has OPT technology, translates adult words, that is, high-pulse light equipment for medical doctors, and has perfect pulse technology.
To extend, all high-light beauty equipment is based on the principle of thermal selective effect of light, and the difference in specific efficacy and patient tolerance is affected by many factors in the equipment. One of the important factors is the Pulse waveform control and pulse width modulation. The medical doctor claims that his waveform and pulse width control have been perfected, so OPT is used to express and elaborate, which belongs to the attributive of IPL.
The second problem is that the hair removal laser and skin rejuvenation laser are different in the target tissue and the depth of the location. One is the hair follicle and the other is the collagen. Therefore, the wavelength, pulse width, and energy are different. The differences are very large. Can’t say a word.
The third problem is that there are many types of laser hair removal devices, and the core of the entire flashlight dares to call itself a copycat of strong light hair removal. In general, in terms of laser intense hair removal, the efficacy and safety are a double-edged sword, which cannot be achieved at the same time. In order to have good efficacy, it must have high energy, so the natural risk is higher, and the safety is lower. To ensure safety, energy will be limited to a very low level, and its efficacy is conceivable.
