The multi-hole treatment method described above is used to remove collagen from skin without removing or damaging the epidermis, unlike conventional procedures (laser, peeling, etc.) in which wrinkles and pigmentation are treated using the regeneration of damaged skin by peeling off the skin . This is a new conceptual cell reconstruction method.

In addition to not having such side effects, the simple and safe multi-hole procedure is a natural wound healing process caused by the penetration of many saliva into the skin, resulting in a new structure and rearrangement of the dermis, As it is pulled tightly, it can reduce fine lines and improve pigmentation, so it can return to healthy and clean skin. In addition, hundreds of saliva can provide hundreds to tens of thousands of passages in a few minutes to deliver the active ingredient, such as the latest active peptides, to further maximize the therapeutic effect.

As a method of forming a multi-hole in the skin of a human body, there are a method using a multi roller needle and a method using a laser. In recent years, a method using a gun equipped with a micro needle, A method of efficiently producing fine holes has been proposed.
