What to know
Digested into ordinary amino acids, so your body decides where they go — not necessarily your skin. Early evidence is modest and largely industry-funded.
Interactions & cautions
- Low risk; adequate protein does much of the same job.
Do you actually need it?
If you already eat enough protein, the benefit is unclear.
