Castor oil comes from the castor plant, Ricinus communis, which commonly grows in tropical regions. Castor oil is often used as a laxative, but it is also beneficial for delicate facial skin. It can be an effective emollient for dry skin and can even help to detoxify and cleanse skin. However, castor oil should always be used under the supervision of a physician because it can cause rashes.
According to North Carolina State University, castor oil is detoxifying and helps to break up oils on the face that clog glands and pores. Organic Facts reports that castor oil contains a compound called undercylenic acid, which can help to disinfect the skin and even kill bacteria that cause skin conditions such as acne. Detoxification can be easily done by rubbing the oil into the skin each night and then washing off the excess.
According to Organic Facts, castor oil can be very moisturizing and can even soften dry skin and rough age spots. According to Palomar Community College, it is an excellent skin emollient and even helps with skin conditions like dermatitis, which can cause severely rough, dry skin. Using castor oil on a nightly basis can be especially helpful in the winter months when skin is at its driest.
According to North Carolina State University, castor oil can also help to cleanse the skin of dead skin cells that are clogging the sebaceous glands. Rubbing castor oil on your face helps to pull out impurities in the pores. This can help to decrease breakouts on the skin that are often caused by these clogged glands. For this method, massage castor oil into the skin and then wash it off with warm, soapy water.
