Jojoba (pronounced "ho-HO-bah") oil is actually composed of liquid wax esters rather than oil. The golden wax is cold pressed from the bean of the jojoba plant. The body's natural sebum also contains wax esters, which act as a natural moisturiser and environmental barrier for the skin. Wax ester production steadily decreases with age, emphasising wrinkles and dry skin conditions such as eczema and psoriasis. Jojoba oil is an ideal ester replacement and dry skin treatment.
