PromaEssence-SPT is a degradation product of silk protein, which is obtained by hydrolyzing natural silk under appropriate conditions. With different control conditions, silk peptide products of different molecular weights can be obtained.

(1) Strong and long-lasting moisturizing ability. Silk protein can absorb up to 50 times the weight of water, and lasting moisturizing

(2) Natural anti-wrinkle, promote collagen secretion. Its molecular structure is similar to that of the collagen fibers that make up the skin. It can naturally enhance the elasticity of the skin. It is called the fiber queen. The amino acids contained in it are necessary for the fission and proliferation of a large number of cells, thereby accelerating skin metabolism. Prevent the formation of wrinkles, tighten the skin, smooth and delicate.

(3) Strong whitening. The melanin in the skin is formed by the oxidation of tyrosinase. Silk fibroin can strongly inhibit the formation of tyrosinase and keep the skin white and delicate.
