Ageing occurs in all organs of the body; however, the skin appearance, such as wrinkles and furrows, is markedly observed for ageing notices. It is a challenging work for cosmetic scientists to find the means for reducing the changes on the skin appearance due to ageing. Application of cosmetic products containing oils with antioxidant activity is widely acceptable to benefit healthy skin. According to the barrier function of the stratum corneum, novel vehicles or formulations such as microemulsions and nanoemulsions are necessary for the skin penetration enhancement. The efficacy of antiageing actives can be achieved when the actives can pass through the stratum corneum and reach the dermis, their targeting site. In this article, ageing theories, oils with antioxidant activity, skin structure as well as microemulsions and nanoemulsions containing antiageing actives will be focused.
