Abstract
The invention discloses a facial skin grease measuring and positioning device, which comprises a support, a lamp tube and a projection assembly, wherein the lamp tube is installed on the support, the projection assembly is arranged in the lamp tube, and the projection assembly comprises a light source, a condenser, a projection plate and an optical lens which are sequentially arranged in the light path projection direction; and light emitted by the light source penetrates through the projection plate and then is emitted out through the optical lens, a square latticed projection can be formed on the face of a subject, and the center of the square latticed projection has a cross-shaped positioning coordinate which is used for accurately positioning a to-be-detected position of the face of the subject. According to the facial skin grease measuring and positioning device, the device does not need to make contact with the skin, the support is not prone to deviation, accurate positioning can be achieved, the positioning coordinate is always kept on the measurement site during measurement, and the device has important value for accurately measuring skin grease and objectively evaluating the efficacy of oil-control cosmetics. The invention further provides a facial skin grease measuring system comprising the facial skin grease measuring and positioning device.
Description
technical field [0001] The invention relates to the field of efficacy testing of cosmetics, in particular to a measuring and positioning device and a measuring system for facial skin oil. Background technique [0002] With the rapid development of the beauty and health industry, the scale of cosmetics consumption in my country has reached the level of 100 billion. Facing the trend of rapid growth in cosmetics consumption, in order to protect the legal rights of consumers and promote the healthy development of the cosmetics industry, accurate and effective development of cosmetics Efficacy testing is of great significance to provide objective basis for cosmetic efficacy claims. Accurately measuring the changes in physiological parameters of the target skin before and after the use of cosmetics is the basis for objectively evaluating the efficacy of cosmetics. As we all know, the physiological parameters of the skin are closely related to the anatomical position of the body, e...
