Castor oil is extracted from the bean of the castor oil plant (Ricinus communis). It is a mild laxative and is also used in alternative medicine for rheumatism, hair care, menstrual problems and as an anti-inflammatory. It may also be beneficial for the skin.
As we grow older, our skin gradually loses its elasticity and begins to sag. This is a natural process, but, according to Skin Help, a website devoted to skin care, it may be exacerbated by rapid weight gain or weight loss, high alcohol intake, excessive sun exposure or smoking. One of the key factors in maintaining youthful skin is to keep it moisturized. Dry skin ages rapidly and will lose its elasticity quicker.
