What is a collagen neck mask?

Special introduction to collagen 

absorbable neck mask Through 5D wrapping technology, collagen and other effective active ingredients can be locked in the neck mask, and then evenly transported through the elastic grid structure during use. (Skin absorption is fastest when the skin temperature is between 35.8-36.5°C and the pH value is between 6.0-7.0). After the skin absorbs the effective ingredients in the neck mask, the neck mask will become more and more transparent, and the collagen can be seen being absorbed.
