Introduction The skin is the outermost part of the human body and serves to protect the body from outside influences. One that causes skin damage is free radicals [1]. Free radicals in the body are formed due to air pollution, ultraviolet light, unhealthy lifestyles and cigarette smoke. This can cause skin damage and the need for skin care such as the use of moisturizers [2].
