The preparation method of the whitening melatonin mask is suitable for the whitening melatonin mask and comprises the following steps:

s1, soaking the mask sheet: selecting a first-type fiber sheet with the thickness of 0.4-0.9mm, cutting the first-type fiber sheet into a shape of a facial contour, processing capillary holes 11 on the surface of the fiber sheet through a conical probe, then soaking the fiber sheet in deionized water to control the water content of the fiber sheet to be 55-75%, then attaching a waterproof breathable film 12 to one side of the fiber sheet, and processing communicated elliptical through holes 13 on the edge of the first-type fiber sheet to obtain a water storage sheet 1;

s2, pressing the mask pieces: selecting a two-type fiber sheet with the thickness of 0.6-1.4mm, cutting the two-type fiber sheet into a shape of a facial contour, extending the two-type fiber sheet into the two-type fiber sheet by using a spherical needle head, scalding a cavity 21 in a vacuole shape, then spraying distilled water on the surface of the two-type fiber sheet, cooling to 0-5 ℃ and storing to obtain a carrier sheet 2;

s3, melatonin filling: pouring melatonin into the paper film ball 3, sealing, fixing the ring strip 211 and the ring piece 31 on the paper film ball 3 through heat bonding, quickly drying the carrier piece 2 in S2 after the carrier piece is recovered to normal temperature, coating adhesive on the surface of the ring strip 211 to be fixed in the cavity 21 of the carrier piece 2, and finally, thermoplastically fixing the annular resin sheet to the cavity 21 at the port of the carrier piece 2;

s4, packaging the mask pieces: and (3) attaching the upper water seepage membrane 4 to the other side of the water storage sheet 1 in the step (S1) to enable the water storage sheet 1 and the waterproof breathable film 12 to wrap the water storage sheet 1, then attaching the carrier sheet 2 in the step (S3) to the water seepage membrane 4 to enable the cavity 21 side in the carrier sheet 2 to face outwards, and finally sealing the carrier sheet into a vacuum bag for packaging.

When in use, the water storage sheet 1 and the carrier sheet 2 are matched, the film sealing strip 41 is torn along the circumferential edge of the mask before use, so that the brace is separated from the water seepage diaphragm 4, the deionized water in the water storage sheet 1 is immersed into the carrier sheet 2 along the water seepage diaphragm 4, along with the process of applying the facial mask on the face, moisture enters the paper film ball 3 in the cavity 21, meanwhile, the water storage sheet 1 generates corresponding shape change along with the contour of the facial skin, so that the shape of the capillary hole 11 in the water storage sheet 1 is changed, the water reserved in the capillary holes 11 is squeezed, so that the water content in the cavity 21 of the carrier sheet 2 is increased, so that the paper film ball 3 is broken after absorbing excessive moisture, the melatonin component contained is mixed into deionized water, and flows to the surface of the skin through the micropores 22, and the waterproof breathable film 12 arranged on the surface of the water storage sheet 1 keeps the permeability of the skin when the mask is applied; the through holes 13 arranged at the edges of the water storage sheet 1 are matched with the expansion strips 131 to store excessive water in the water storage sheet 1, so that the situation that water in the use process flows down from the face when the facial mask is applied to the surface of non-water-deficient skin is avoided, the use experience of the facial mask is reduced, meanwhile, in the deformation process after the expansion strips 131 absorb water, the oval through holes 13 are opened, the communication openings among the adjacent through holes 13 are enlarged, the water stored in the expansion strips 131 is mutually transmitted among the through holes 13, the weight among the expansion strips 131 is balanced, and the stable state of the facial mask applied to the face is ensured; the ring strip 211 is arranged in the cavity 21 and used for positioning the paper film ball 3, so that melatonin ingredients in the paper film ball 3 are in balanced contact with the skin surface on the whole carrier sheet 2 in the use process after the facial mask is applied to the face, meanwhile, the positioned paper film ball 3 avoids inertia force impact generated in the moving process of the facial mask, the stability of the structures of the cavity 21 and the paper film ball 3 is maintained, and sodium polyacrylate filled in the ring strip 211 is used for enabling moisture in the water storage sheet 1 to expand and press the sodium polyacrylate to the paper film ball 3 after entering the cavity 21 in the carrier sheet 2, so that the breakage of the paper film ball 3 is promoted, and the melatonin ingredients in the paper film ball are ensured to be transferred to the skin surface in real time; the cutting strip 212 arranged inside the ring strip 211 is matched with the arc-shaped backing ring 213 at the bottom of the ring strip, under the expansion action of polyacrylate, the ring strip 211 is pressed to the paper film ball 3 below along a set angle, the outflow direction of melatonin from the paper film ball 3 is controlled, and the ribs 221 arranged on the micropores 22 simultaneously cut the bottom of the paper film ball 3 in contact, so that melatonin components in the melatonin directly flow out along the micropores 22, the cut formed by the ring strip 211 at the top of the paper film ball 3 is communicated with the bottom of the paper film ball 3, and the melatonin in the paper film ball 3 flows out; the ring piece 31 arranged on the paper membrane ball 3 limits the paper membrane ball 3 at the position of the micropore 22 by utilizing the size of the ring piece 31 larger than the micropore 22 under the extrusion action of the expansion ring strip 211 in the cavity 21, and the broken paper membrane ball 3 part leaks from the micropore 22 and protrudes from the surface of the carrier sheet 2, so that the carrier sheet 2 and the skin are in a different contact state, a gap is formed between the skin and the carrier sheet 2, and the permeability of the mask in use is enhanced by matching with the waterproof breathable film 12 outside the water storage sheet 1.
