Laser beauty equipment is also widely used in beauty medical institutions, such as dot matrix laser therapeutic apparatus, laser hair removal equipment, skin beauty laser system and so on. The pixel laser therapeutic instrument divides each pulse laser into nearly 100 micro laser pulses. When these tiny laser beams act on the skin surface, those densely distributed points (lattice) look like imaging "pixels".
Therefore, it is named, the high-energy and specific wavelength laser output acts on the scar tissue of the skin, which can pass through the stratum corneum of the epidermis and directly reach the collagen layer, with little influence on the skin and remarkable therapeutic effect.

The household beauty instrument is in direct contact with the skin when in use. If harmful substances in the metal coating of massage head or handle exceed the standard, there may be health and safety risks.
In this comparative experiment, the chemical safety indexes of 10 samples were tested according to the recommended standards of domestic beauty instruments and the relevant standards of the European Union. It was found that the nickel release of 6 samples in 10 did not meet the requirements of relevant standards, accounting for 60% of the total samples.
At present, metal ion plating technology is widely used in domestic beauty instruments in China. Adding nickel in the processing can increase the wear resistance of products and make the metal coating of beauty instruments brighter. However, nickel is also the most common sensitizing metal. Long-term or repeated use of products with unqualified nickel release may cause allergic symptoms.
