Silk Peptides Research Guide

Full name: Hydrolyzed Silk Fibroin Peptides

Bioactive peptides from silk fibroin (Bombyx mori). Rich in glycine, alanine, and serine, they form moisture-retaining films while providing amino acid building blocks.

How Silk Peptides Works

Form hydrogen-bonded films on skin for moisture retention. Absorbed peptides provide substrates for keratin/collagen synthesis. Exhibit antioxidant and tyrosinase-inhibiting activity.

Dosing Protocol

• Typical dose: 1-5% topical or 2-5g oral
• Frequency: Daily
• Duration: 8-12 weeks
• Route: Topical or Oral

Reported Benefits

• Intense hydration
• Moisture barrier support
• Skin smoothing
• Antioxidant activity
• Brightening effects

Potential Side Effects

• Well tolerated
• Silk allergy possible (rare)
