面膜上的珍珠膜是什么?

珍珠膜是面膜上的 tiny, transparent, pearl-like membrane. It is a type of cell membrane that is found in many organisms, including humans. The pearl-like appearance of the membrane is due to the fact that it is made up of a protein called keratin. Keratin is a strong, fibrous protein that is found in hair, skin, and nails.

The pearl-like membrane is responsible for the unique properties of the cell. It is transparent, allowing light to pass through, but it is also impermeable to water and other molecules. This allows the cell to regulate its water balance and to transport nutrients and waste products.
