Silk protein (also known as sericin) is a protein substance and has the ability to bind water to the skin.
What are the benefits?
Silk protein has the ability to bind water to the skin. However, the skin cannot differentiate if the protein applied to it is obtained from animals or plants. It is said to defend the skin from dehydration while leaving a smooth feeling on the skin. Their low molecular weight, it is believed, allows for penetration into the top layers of the corneum layer.
