27 Health Benefits of Castor Oil

6. Cosmetic Effects

Castor oil may improve complexion. As opposed to the ingredients in some store-bought topical treatments, which can dry out skin at the same time as spots, castor oil moisturizes the skin while cleansing it. Some people use it as a general cleaner to remove spots and dead skin. It is possible to be allergic to the oil, however, so anyone trying this method should test a small patch of skin on the inside of the elbow before full-scale application.
