Product Introduction:

Silk Amino Acids are natural, water-soluble glycoprotein fragments obtained by hydrolyzing silk proteins (predominantly fibroin and sericin). Known for their exceptional moisture retention and conditioning properties, they are widely used in skincare and haircare formulations to enhance hydration, improve texture, and create a smooth, silky feel. Their low molecular weight (approximately 90 Da) enables deep penetration into skin and hair fibers.

Main Functions and Benefits:

1. Moisturizing humectant: Excellent at binding and retaining water, helping maintain skin and hair hydration.
2. Hair and skin conditioning: Leaves hair soft, smooth, and shiny; improves skin texture and creates a protective, semi-occlusive barrier.
3. Deep penetration and barrier support: Small molecular size (~90 Da) enables thorough absorption and forms a subtle protective film, making it highly substantive.
