Pearl powder is made by grinding whole pearls — typically freshwater mussels or saltwater oysters — into an ultrafine powder. It has been used in Traditional Chinese Medicine for over 2,000 years, appearing in classical texts as a remedy for everything from skin complaints to heart palpitations and poor sleep. Empress Wu Zetian of the Tang Dynasty is among the most famous historical users, reportedly consuming it daily for skin and longevity.
The key active components are calcium carbonate (a highly bioavailable mineral form), conchiolin proteins, and free amino acids. Conchiolin is thought to stimulate fibroblasts — the skin cells that produce collagen — and may also influence melanin production, explaining its skin-brightening reputation. The amino acid glycine, present in high concentration, supports both collagen synthesis and calming GABA-like activity in the nervous system.
Oral forms include loose powder (traditionally mixed into water, juice, or tea), capsules, and tablets. Topical forms — creams, serums, and sheet masks containing pearl extract or powder — are widely used in Korean and Chinese beauty products. Quality varies considerably: hydrolyzed pearl (acid or enzyme processed) improves amino acid bioavailability compared to raw powder. Nano-milled or ultrafine grades are preferred for topical absorption.
Pearl has been used medicinally in China since at least the first century CE, referenced in the Shennong Bencao Jing (Divine Farmer's Materia Medica). It features prominently in TCM for calming the spirit (shen), clearing heat, and improving complexion. Ayurvedic medicine uses a similar preparation called Mukta Pishti, where pearl is ground with rose water and used for heart conditions, anxiety, and pitta-related disorders. Its use as a cosmetic ingredient spans Tang Dynasty China through Elizabethan Europe.

The published evidence for Pearl Powder is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
