Ingredient review
Mother of Pearl Extract
INCI: MOTHER OF PEARL EXTRACT
A gentle, natural ingredient that may add a subtle glow and skin conditioning benefits, but scientific evidence is limited and mostly traditional.
In plain English
Mother of Pearl Extract is made from the shiny inner layer of oyster or mussel shells. In skincare, it's used to give products a pearly look and is thought to help brighten the skin and keep it feeling soft. However, there isn't much modern science to prove these effects, so think of it as a gentle, feel-good ingredient rather than a powerful active.

What it is
A powdered extract obtained from the nacre (mother of pearl) layer of mollusk shells, primarily composed of calcium carbonate and trace organic proteins.
How it works
In cosmetics, it acts mainly as a skin conditioning agent and opacifier. The fine particles may reflect light, giving a temporary luminous effect on the skin. The trace proteins and minerals are believed to support skin hydration and barrier function, though these effects are not well-documented in clinical studies.
