Silk Protein Peptide Product Description

Silk peptide is the degradation product of silk protein, which is obtained by hydrolysis of natural silk under appropriate conditions. Under different control conditions, silk peptide products with different molecular weights can be obtained, all of which are transparent pale yellow liquids with molecular weights between 300 and 5000.

What is Silk Peptide Used For?

1. Moisturizing

There are many hydrophilic groups on the molecular structure of silk peptide. This structure shows that silk peptide is a natural moisturizing factor and has a good moisturizing effect. At the same time, silk peptides have small molecules and strong permeability. They can combine with skin epithelial cells through the stratum corneum, promote cell metabolism, and make skin shiny, moisturizing, and elastic.

2. Whitening spots

The silk peptide obtained by hydrolysis of natural silk can inhibit the formation of tyrosinase, accelerate skin metabolism, clear the melanin at the bottom of the skin, and build a skin protective barrier.

3. Natural anti-wrinkle

Another significant effect of silk peptides is: anti-aging. Silk peptides are fibrous proteins whose molecular structure is similar to the collagen fibers that make up the skin, and can naturally enhance the elasticity of the skin.

Silk peptide, rich in 18 amino acids that are the same as human skin, is currently an excellent cosmetic additive recognized internationally.

4. Repair the barrier

Silk peptide has the reputation of "the second skin" of human beings, because silk peptide contains 18 kinds of amino acids similar to the human body, which can be directly absorbed by the skin. The secrets of silk beauty and skin care have been recorded as early as the Ming Dynasty. Silk peptides contact the skin, improve the skin's defense barrier, and penetrate into the base to repair skin damage.

Applications of Silk Peptide Powder

1. In the field of cosmetic raw materials, it can be used in cream, cream, lotion cosmetics and shampoo, hair care, bath products.

2. Used as food nutrition fortifier.
