Castile Soap is made with Pure Olive Oil. Castile soap is prefect for anyone who suffers from allergies or skin sensitivity. Castile soap lets your skin breathe and encourages the natural process of shedding dead skin cells. Olive oil is rich in antioxidants such as vitamins A and E. Regular use of castile soap can help protect against skin cell degeneration and can, therefore, delay the appearance of wrinkles and accelerated ageing.
