There no two sides for the face paper, if itself is filled with essence and plays the core function.
Some consumers commonly think that there is two layer of the facial mask and could not distinguish which one layer is positive or negative.
However, due to the softness and thinness of some face paper, once it is soaked by essence it is easy to stick together and hard to be separated. Also, it is easy to be pulled and deformed due to insufficient stretch, and could not stick to apply on the face.
So, some facial mask will include two layers—one is ACTS as the face paper’s "Supporting Role", another is the face paper itself.
Beihao’s facial mask could do not use ACTS as the face paper’s "Supporting Role", and its face paper doesn’t has the front side and the back side.
