Ground pearl powder historically used in Chinese and Korean traditional medicine. In modern cosmetics it is a marketing ingredient for 'radiant skin' and a decorative filler in powders and illuminating creams. It consists mostly of calcium carbonate (95%) and conchiolin protein. No evidence base for an anti-age effect.
Topical application
FNo evidence or proven inefficacy for this route of administration.
No clinical studies with adequate methodology. Marketing claims of 'wrinkle reduction' and 'brightening' are unsupported. In formulation it acts as a fine decorative filler with a mild light-reflecting effect – a purely surface-level cosmetic radiance.

Mechanism. Claimed anti-aging effect through collagen synthesis stimulation (conchiolin contains amino acids – proline, glycine).
