Many people have heard that castor oil has moisturizing benefits, but what is the principle behind it?
According to scientific research, the main reasons include the following aspects:
High content of fatty acids: Castor oil is rich in fatty acids, especially palmitic acid and linoleic acid. These fatty acids can form a protective film on the skin's surface to prevent water evaporation, thus maintaining the skin's moisture content and alleviating issues such as dryness and roughness.
Antioxidants: Castor oil contains abundant antioxidants, such as vitamin E, which have antioxidant and anti-inflammatory properties. These antioxidants help protect the skin from free radical damage, slow down the aging process, and promote skin regeneration and repair.
Antibacterial properties: Some studies suggest that castor oil has certain antibacterial and antifungal properties, which can help reduce bacterial infections and inflammation on the skin surface, maintaining skin cleanliness and health.
