In recent years, with the continuous improvement of living standard of people, the pursuit of beauty is higher and higher, especially as facial skin of 'facial engineering', common chemical beauty skin care products can not meet the requirements of consumers on beauty skin care, so that beauty instruments which take effect faster than common chemical skin care products and have lower maintenance price than medical beauty are gradually favored by consumers, more and more enterprises are introduced in succession, the market scale is continuously increased, and the number of the beauty instruments reaches 65 yuan in 2019. In 1963, goldman reported the success of using ruby lasers for benign skin lesions and tattoo treatment, marking the beginning of the application of optical devices in the field of skin cosmetology. After decades of development, professional optoelectronic beauty equipment is continuously developed and updated, and a plurality of 'incurable diseases' of skin, such as port wine stains, nevus taitian, tattoos and the like can be effectively treated by the laser beauty equipment. The technology is advancing, the optical beauty instrument is also innovated and improved, and simple basic beauty projects such as skin care, nursing and whitening can be realized by independently operating the personal beauty instrument by a user. Different from professional medical and beauty instruments of hospitals and beauty institutions, the household beauty instrument can be safely operated in the family range, has the advantage of free and flexible use, and is suitable for the requirements of most skin-care girls. Based on the LED light source, products for improving the health condition of facial skin through the photobiological regulation effect are favored by consumers, such as photon masks and the like.

Laser and intense pulse light cosmetic skin treatment devices (e.g., depigmentation, wrinkle reduction, whitening or other common skin disease treatments) have been accepted by medical systems and the cosmetic industry at home and abroad. The treatment scheme has the characteristics of quick response, belongs to invasive treatment, and can cause a burning feeling of an irradiated person, and certain loss and after-effect on normal tissues of a human body. The experimental and theoretical basis of the application of the LED light source to the biomedical field is laid by KARU and the like. The experimental research provides scientific basis for the application of the LED light source in the biomedical field from the cellular molecular level. With the development of LED light source technology, the LED has greatly improved luminous efficiency, color stability, chromaticity and other parameter performances. Relevant foreign researches show that the LED light energy skin beautifying system is a novel effective anti-aging tool; it is popular in foreign industries due to its distinctive characteristics. The LED light source has the following characteristics and advantages: 1) Is safe and reliable. The LED is a non-thermal effect solid-state cold light source, and cannot cause thermal damage to skin, eyes and the like; in addition, the LED light source has the advantage of long service life. 2) The LED lighting lamp is energy-saving and environment-friendly, high in LED light-emitting efficiency and energy-saving in illumination. 3) The wavelength range is wide. The wavelengths at which LEDs emit light have covered from the ultraviolet to the near infrared. 4) The spectrum is pure, the half-wave bandwidth of the spectrum is narrow, and can be controlled within 10 nm. Household LED beauty treatment instruments on the market at present mainly comprise several forms: hand-held type, the face guard formula, big bank of lamps etc. some shortcomings of ubiquitous, it is little either to shine the area, or the volume is great, accomodate and carry inconveniently, or have potential safety hazard and the price/performance ratio is low that prices. With the progress of photoelectronic technology, the household photon beauty instrument develops towards the direction of intellectualization, miniaturization, green and energy conservation. Micro-LEDs refer to inorganic LEDs with the size of 10-100 mu m, the current main application range is display application, and the Micro-LEDs have many advantages, related researches are carried out on the aspect of biological medicine health, but specific products are not published yet.
