Embodiment approach 1
[0032] A macro measuring instrument comprising a macro measuring board and a macro camera,
[0033] A macro-distance measurement board, on which a flat plate 3 is arranged in a matrix with square grids 1 whose length and width are 1 mm. The surroundings of the square lattice matrix 2 are borders. The flat panel is made of transparent flexible material.
[0034] When in use, stick the micro-distance measuring board on the volunteer's face where there is chloasma. Since the material of the macro-distance measuring board is transparent, the shape of the chloasma can be revealed. Then take pictures with a macro camera, copy the electronic photo to the computer and enlarge it, and calculate how many square grids 1 there are in the melasma area. If the grid on the edge of the melasma only has part of the melasma, it is counted as 0.5 square grids 1 , which is 0.5mm 2 . The area of chloasma = grid number * 1mm 2 . In this way, the area of the irregular melasma can be roughl...
Embodiment approach 2
[0038] A macro measuring board, handles 4 are respectively arranged on the four sides of the frame. The plate is made of transparent silicone. Or the flat panel is made of transparent flexible plastic.
[0039] The handle 4 can facilitate the operator to hold the macro measuring board, and can prevent the operator's hand from covering the square grid 1 when taking pictures with the macro camera.
[0040] The embodiments of the present invention and the results thereof will be further elaborated below.
Embodiment 1
[0043] A freckle-removing water for lightening facial chloasma and improving freckle regeneration and a preparation method thereof, comprising the following steps:
[0044] (1) Get 210 parts by weight of western Tibetan cabbage leaves, 75 parts by weight of Phalaenopsis petals, and 140 parts by weight of chrysanthemum chrysanthemum leaves and dry them at room temperature for 10-15 days, that is, 25 ° C, and the relative humidity in the room is 45%. -55%;
[0045] (2) Put the dried Chinese cabbage leaves, phalaenopsis petals, and chrysanthemum leaves into a mortar and grind them, and mix them with 300 parts by weight of absolute ethanol to obtain three kinds of plant tissue mixtures;
[0046] (3) After ultrasonically extracting the three plant tissue mixtures obtained in (2) at room temperature for 40 minutes, filter to remove absolute ethanol, pour the remaining mixture into a beaker, add 600 parts by weight of water, seal it with a plastic wrap, and place it for 24 hours Get...
