Description

Hot compress pack containing bioactive components for face and preparation method thereof

Technical Field

The invention belongs to the technical field of hot compress products, and particularly relates to a hot compress cover containing bioactive components for faces and a preparation method thereof.

Background

After people apply the facial mask, the facial mask is beaten, so that pores are expanded, blood circulation is accelerated, and the absorption rate of facial mask liquid is improved. In order to make the facial mask liquid be absorbed more conveniently and rapidly, the hot compress steam mask can be worn while the facial mask is applied. The skin layer of the existing hot compress steam mask is usually made of common non-woven fabrics, although the common non-woven fabrics have the advantages of light weight, no toxicity and no stimulation, due to the characteristics of air permeability and water impermeability, the non-woven fabrics of the skin layer absorb a part of facial mask liquid, so that the facial mask is dried quickly, and the absorption effect of the facial mask liquid on the face is weakened. For example, the Chinese utility model patent (publication number: CN 208464613U) discloses an intelligent hot compress steam mask, the skin layer is made of common non-woven fabric.

In addition, when the existing hot compress steam mask is used, the phenomenon that the mask is not attached to the skin and is raised still exists around the mask.
