💧 What Is Castor Oil and Why Use It on Eyelashes?

Castor oil is a thick, nutrient-rich oil extracted from castor beans. It’s especially high in ricinoleic acid, a compound believed to help:

Strengthen lash follicles
Deeply moisturize brittle lashes
Reduce lash breakage and shedding

While clinical evidence is still emerging, anecdotal reviews and traditional use point to noticeable improvements in lash volume and shine.
