The article states that castor oil can enhance skin hydration and reduce transepidermal water loss. The stratum corneum is described as the body's main shield against pathogens, allergens, and water loss. Castor oil functions as an occlusive humectant by sealing the skin surface and trapping moisture. Ricinoleic acid bonds to the skin surface more aggressively than most plant oils because of its hydroxyl group.
