Castor oil is a distinctive botanical oil pressed from the seeds of the Ricinus communis plant. Naturally high in ricinoleic acid, it has a thicker, more viscous texture than most plant oils, giving it a unique ability to cling gently to the skin and deliver lasting softness.

Traditionally used in both skincare and wellness practices, castor oil is valued for its conditioning properties and its ability to support the appearance of smooth, well-nourished skin. In oil-based cleansers, it plays a particularly important role, helping to lift away impurities while maintaining the skin’s natural balance.

In M. Carya formulations, castor oil is used with intention. Its richness is carefully balanced with lighter oils to create formulas that feel effective, comforting, and refined rather than heavy.
