By observing the body hair of the human body, the body hair of the human body is not attached to the skin of the human body but is erected on the skin of the human body in a state of being approximately perpendicular to the skin, and thus, when the adhesive layer 42 is directly attached to the skin of the human body, the erected body hair falls down, and the falling body hair and the body hair may overlap, so that the adhesive layer 42 cannot be fully contacted with the body hair below after overlapping, particularly, the body hair of a patient with thicker body hair can warp, the mutual overlapping condition of the body hair is more remarkable after the body hair is pressed down, and if the adhesive layer 42 cannot be fully contacted with the body hair, the body hair of the attaching area cannot be fully removed in the subsequent tearing process. In the above-described embodiment, however, the adhesive layer 42 is folded when pressed against the skin of the human body, and the folded portion of the body hair is held by the folded portion and is warped so as not to fall down and overlap with other body hair, thereby reducing incomplete hair removal due to the overlapping of the body hair being pressed down.

In this embodiment, the base layer 41 has an arcuate cross section such that the curved surface 412 has a larger area than the flat surface, and thus more area can be used to form the wrinkles after being depressed.
Further preferably, as shown in fig. 5, the curved surface 412 may include,
a plurality of first grooves 413 spaced equidistantly from each other and disposed in a length direction, on an outer surface of the curved surface 412;
a plurality of second grooves 414 spaced equidistantly from each other and disposed in a length direction, and located on an outer surface of the curved surface 412;

In this technical solution, the first groove 413 disposed on the outer surface of the curved surface 412 is easy to concave when the curved surface 412 is pressed down, and the second groove 414 disposed on the inner surface of the curved surface 412 is easy to convex when the curved surface 412 is pressed down, and the wrinkles generally need one concave position and two convex positions, so that the first groove 413 and the second groove 414 spaced from each other can be more beneficial to the formation of the wrinkles.
Further preferably, one first groove 413 and two second grooves 414 may be a group, the first groove 413 is disposed in the middle, the second grooves 414 are disposed at two sides, and a plurality of groups are disposed at intervals, so that each group of grooves forms a fold, and the folds for clamping the standing or warping body hair can be formed efficiently as long as the distance between the groups is controlled.
As an alternative embodiment, curved surface 412 may include,
a plurality of first grooves 413 spaced equidistantly from each other and disposed in a width direction, on an outer surface of the curved surface 412;
a plurality of second grooves 414 spaced equidistantly from each other and disposed in a width direction, on an outer surface of the curved surface 412;
the first groove 413 and the second groove 414 are disposed at a distance from each other.
Since the grooves provided in the length direction and the grooves provided in the width direction have the same operation principle, the description will not be repeated, and since more grooves can be provided in the width direction, the first grooves 413 and the second grooves 414 can be selectively provided in the width direction from the viewpoint of efficiency of forming wrinkles.
Further preferably, the first groove 413 may include a straight groove; or alternatively
The second grooves 414 may include linear grooves; or the first groove 413 and the second groove 414 each comprise a straight groove.
Further preferably, the interval between the first groove 413 and the second groove 414 may be set to be smaller than the height of the protrusion of the curved surface 412, so as to avoid that the curved surface 412 area separated by the grooves cannot smoothly form wrinkles.
Further preferably, the base layer 41 may include a compressible hollow structure 415 disposed between the planar surface 411 and the curved surface 412.
This solution provides a hollow structure 415 between the flat face 411 and the curved face 412, which is advantageous for forming a fold when the curved face 412 is depressed.
Alternatively, a discrete hard layer attached to the inner surface of the curved surface 412 may be disposed between the flat surface 411 and the curved surface 412, and the space between the hard layers corresponds to the first groove 413 or the second groove 414, and the hard layer may be used to separate the space between the grooves or between the groove groups to prevent the wrinkles from affecting the efficiency of adhering body hair, and the hard layer may be formed by direct punching with a cutter.
In a preferred embodiment, the adhesive layer 42 is made of one of a rubber paste and an adhesive resin.
In the technical scheme, the rubber paste and the viscous resin are physical depilatory materials under the obtained normal temperature condition, and the preparation is simple and the cost is low. In a preferred embodiment, a release film may also be provided overlying adhesive layer 42.
