Description

Technical Field

[0001] The utility model relates to the field of light therapy instruments, in particular to a multifunctional beauty instrument with hair removal effect. Background Art

[0002] IPL beauty instrument uses enhanced light of specific frequency to directly irradiate the skin surface. It can penetrate deep into the skin and selectively act on subcutaneous pigments or blood vessels to decompose spots and close abnormal red blood vessels. It can remove various blemishes on the skin. At the same time, photons can also stimulate the proliferation of subcutaneous collagen and reorganize the original collagen tissue, thereby shrinking pores, reducing wrinkles, and restoring skin elasticity, health and luster.

[0003] At present, the IPL beauty instrument products on the market generally have one beauty head, which can be suitable for IPL light of one frequency band, such as an IPL photon beauty instrument disclosed in Chinese patent document CN 219614758 U; in order to be suitable for IPL light of multiple frequency bands, two methods are generally adopted. One is to use a replaceable head, that is, one beauty head, and replace multiple replaceable heads of different frequency bands. When the light of which frequency band is needed, the corresponding replaceable head is replaced; the other is to replace the filter, such as an IPL photon beauty instrument with a cold-keeping replaceable filter disclosed in Chinese patent document CN 215309756 U.
