Distinguish different cosmetic optical instruments and their functions

There are many different optical instruments on the market, which give off different frequency and characteristics of the radiation wave. We can basically tell by its wavelength, energy, output mode, etc.

Ultraviolet light

Ultraviolet light can be divided into ultraviolet A, ultraviolet B and ultraviolet C according to different wavelengths. Uv A has a wavelength between 315-400 nm. It is commonly used for skin detection in beauty applications such as Wood's Lamp, as well as for skin darkening (sun lamp/sun Lamp) and nail art. Ultraviolet B wavelengths range from 280-315 nanometers and are commonly used in medicine to treat leukoetus (also known as white spot or vitiligo). Uv C wavelengths range from 100 to 280 nm and are commonly used for disinfection purposes, such as tool sanitizer. Uv C should not be exposed directly to the skin. Uv instruments are usually output in continuous mode.

Infrared ray

Cosmetic infrared instruments are mainly used to transfer heat energy to the skin for heating purposes. Infrared rays can be subdivided into near infrared (wavelength 0.75 to 1.5 microns), medium infrared (wavelength 1.5 to 5.6 microns) and far infrared (wavelength 5.6 to 1000 microns). Generally speaking, such as heaters, torches, electric furnaces and other infrared emitted more belong to the near infrared, due to wave length, so produce a large number of thermal effect, the human body after long-term exposure will produce skin burns and eye crystal degeneration and other diseases. Infrared ray, because of its long wavelength and relatively low energy, is less concerned about burns when used. Although the naked eye can not see the far infrared, but it is similar to the nature of light, not only can be straight forward, but also can reflect, scatter, penetrate and be absorbed and other actions. Far infrared ray can be quickly absorbed by the human body; Deep into the human body, the far infrared ray will cause the vibration of atoms and molecules, through resonance absorption, forming a thermal reaction, promote the temperature of the deep skin, and make microvessels dilate, promote blood circulation. Examples are: beauty infrared lamp, infrared weight loss heat blanket, far infrared beauty capsule and so on. Beauty infrared instruments are generally output in continuous mode.

Photodiode (LED)

Light-emitting diodes (leds) are popular for cosmetic purposes, as are household and professional cosmetic devices. They give off different wavelengths of light. The diodes display different colors, for example, red leds have a wavelength of about 625-700 nanometers and yellow leds have a wavelength of 590-625 nanometers.

With different wavelength, energy and irradiation time, LED can achieve different effects, such as increased blood circulation, accelerated wound healing, pain relief and skin rejuvenation. Beauty LED optical instruments can be output in continuous mode or pulse mode.

Colored light

Pulsed Light, i.e. Intense Pulsed Light, refers to the manufacture of a high energy, low coherence, and higher essential pulsed light spectrum using the principle of flashing lights (usually xenon flashbulbs). After the energy of light source with different wavelength is irradiated into the skin, various skin problems can be treated at the same time. Xenon flashbulbs emit light of a variety of different wavelengths, which can be output to a specific range of wavelengths through a specific filter for a specific purpose. With different filters, color light can be used to achieve: hair removal, skin rejuvenation, spot removal, improve facial redness, etc. Color light is output in pulse mode.

laser

The word 'Laser' is derived from the first letter of the English word 'Light Amplification by Stimulated Emission ofRadiation', which is short for 'light amplification by stimulated emission ofradiation'. It means that by the principle of "excitation radiation", the amplification of light waves, called "laser". There are many kinds of Laser, with different wavelength, output energy and output mode. Some of the lower output energy is called Low energy laser (LLL). Generally, it is continuous output mode and irradiation for a long time to achieve light energy interaction or photochemical reaction. For example, some lasers are used to lose weight or relieve pain. Some of the larger energy outputs, For example, carbon dioxide Laser (CO2Laser, wavelength 10600nm), rubidium Jacob Laser (Nd:YAG Laser, wavelength 1064nm), Alexander Laser (wavelength 755nm), Ruby Laser (Ruby Laser, wavelength Wavelength 694nm), most of them will be output in the form of pulse, with different pulse duration can achieve different effects, such as plaque removal, skin rejuvenation, collagen hyperplasia, wrinkle removal, pore closure, improvement of concave and convex holes, hair removal, improve vascular problems

Elos-light/E light

E-light is a general term for a technology in which the operating head combines color light and bipolar radio frequencies simultaneously to achieve better results.
