Skin aging is the result of two distinct, biological processes which may occur concurrently: extrinsic aging and intrinsic aging. Extrinsic aging of the skin is exemplified by deep, coarse wrinkles, mottled hyperpigmentation and a marked loss of elasticity and recoil. On the other hand, intrinsically aged skin is a slow process which causes changes in tissue structure and impairs function in the absence of additional chemical, biological and physical factors. Our skin provides a very efficient delivery system for chemicals to enter the body. Unfortunately our skin also absorbs toxic chemicals commonly found in personal care products. Consequently, we should switch to natural skin care products. There has been a very long history in human civilization of the usage of natural products; such as herbs, roots, essential oils and flowers for skin care. A cosmetic formulation including natural products can protect the skin against exogenous or endogenous harmful agents, and help to remedy many skin conditions. Although there are several treatments available for aged skin, oral administration supplements and topical application formulations remain the best approach and should be encouraged to all patients. This chapter focuses on the anti-skin aging effects of natural products, such as polyphenols and terpenes using topical application and oral administration. Future prospective for this field of research will focus on natural products combined with molecular techniques; it will help to maximize the desired anti-skin aging benefits.
