Silk Peptide Smoothing Serum
Tatcha
Tatcha's Silk Peptide Smoothing Serum uses silk-derived peptides (hydrolyzed silk proteins) alongside their proprietary Hadasei-3 complex (green tea, rice, and algae extracts from Japanese beauty traditions). The silk peptides provide both humectant hydration and signal-peptide activity — silk fibroin peptides have been shown in vitro to stimulate collagen and elastin gene expression in dermal fibroblasts. The formulation also includes ceramides for barrier repair and squalane for occlusive moisture retention. The texture is lightweight and absorbs quickly, making it suitable for layering under makeup. This is a premium product — the efficacy-per-dollar ratio is lower than budget peptide serums, but the texture, fragrance-free formula, and skin feel justify the price for many users.
