Application
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.

Prevent the formation of wrinkles, tighten the skin, smooth and delicate.
