The structure of natural silk is very similar to human skin, so it is also called the "second skin" of human body. Silk beauty has a long history in China. As early as the Ming Dynasty in China, silk was used by court ladies for daily beauty and health preservation because of its important medicinal value. According to Compendium of Materia Medica, silk protein powder can eliminate skin dark spots and treat suppurative dermatitis. Modern medical experiments further prove that the protein content of silk is much higher than that of pearl, in which the nitrogen content is 37 times that of pearl, and the main amino acid content is as high as 10 times. It is easier to penetrate into the outer layer of human epidermis and accelerate skin metabolism.
The main component of silk is pure natural animal protein fiber, and its structure is the closest to human skin, with 87% identity. It contains various amino acids necessary for human body, and has the effects of preventing wind, removing dampness, calming nerves, nourishing and balancing human skin. Silk is smooth, breathable, soft, moisture-absorbing, non-itchy and antistatic, and it is a superior material for making close-fitting clothes. Silk quilt with silk as lining has unique qualities and advantages such as close-fitting warmth, fluffy softness, ventilation and health care.
