Why supplement?
Marked asPrimarySupporting
Improves skin hydration
Cocoon sericin is hydrophilic. After hydrolysis it releases short peptides high in serine and aspartic acid that can bind water in the stratum corneum. For people with dry, dull skin, how it feels often lands on the horny layer being less tight and flaky, and smoother to the touch.
Supports hair and nail structure
Fibroin fiber is mainly glycine and alanine repeats; hydrolyzed peptides can serve as structural amino-acid sources for hair keratin and nails. Textile silk waste is often enzymatically cut into food or skincare ingredients. People with dry, brittle hair and nails that split easily map onto this short-peptide set.
