珠光膜的作用
The Role of Pearlescent Membrane
1.珠光膜可以保护面膜的精华和水分，因为现在市面上的面膜越来越薄，膜纸保护精华和水分的功能就会相对下降，这时候珠光膜就会起到很大作用，能够储存精华和水分，使面膜的营养成分不会流失。
1. pearlescent film can protect the essence and moisture of the mask, because now the mask on the market is getting thinner and thinner, and the function of protecting the essence and moisture of the film will be relatively reduced. At this time, the Pearl film will play a great role in storing the essence and moisture, so that the nutrients of the mask will not be lost.
2.贴膜更容易，因为现在的面膜纸都会比较薄，用的时候不好拉扯容易变形，并且用力过度就会撕破，而有了珠光膜就会很好地把面膜贴到脸上，不轻易掉下。
2., sticking film is easier, because the mask paper will be thinner now. When it is used, it will not be easy to pull, it will be easily deformed, and it will tear if it is overexertion.
3.珠光膜起着固定面膜作用，免于面膜损伤变形，同时防止水分蒸发过快。
3. pearlescent film acts as a fixed mask to protect the mask from damage and prevent moisture from evaporating too fast.
