Although there are no studies to support castor oil’s effectiveness against wrinkles, it is said to be a great skin moisturizer. Moisturizing is essential in the prevention and treatment of wrinkles because dry skin causes the skin cells to shrivel and wrinkles to appear [R] [R] [R].
Additionally, castor oil also promotes wound healing and reduces inflammation, which is why the compounds found in castor oil are used in many ointments. Castor oil in ointments can speed up healing and are used in the treatment of pressure ulcers [R] [R].
When added with balsam of Peru, it is effective in healing skin graft wounds. A study was conducted on the use of these two ingredients where 36 people reported faster healing of their skin graft wounds in 11 days [R]. If you have melasma, castor oil added with phenol just might do the trick for you. This combination was proven to reduce melasma discoloration in a study with 30 patients [R].
Castor oil has antioxidant and anti-inflammatory properties. Ricinoleic acid, a major component in castor oil, is responsible for reducing inflammation, while its flavonoids component is responsible for its antioxidant properties [R] [R] [R] [R].
