How to use
What it’s for
Limited human evidence — skin data is in cell culture
Pros & cons
Pros
  • Long history as food and medicine in asia
  • Used in dermocosmetics for moisturising claims
  • At 500 µg/ml it raised collagen in skin cells
Cons
  • That collagen result is cell culture, not people
  • The lower 200 µg/ml dose did nothing for collagen
  • Authors say reproducibility still needs confirming
