Now, on the market is a variety of sheet masks: whitening mask, acne mask, anti-wrinkle mask… Unfortunately, face film has thousands of kinds, the effect is only one, that is “filling water”.
Strictly speaking, there are two main effects of a facial mask: one is to “soak” the cuticle with the moisture carried; The other is to add a layer of sealing film so that the lost water stays in the cuticle. As a result, the stratum corneum absorbs water and expands, lining up tightly and neatly. Under the reflection of the light, the skin will look soft and clear, and even whitening feeling.
But in fact, water only stays in the cuticle and does not enter the deeper skin. As a result, mask “hydration” is only temporary.
