Web1. Intrinsic Skin Ageing. The skin ageing process, particularly visible on the face, is 3-fold, involving our skin, fat and bones. Skin: Over time our bodies produce less collagen and elastin, the skin gets thinner, pores become larger, and wrinkles begin to form, often first around the most mobile areas of the face (“expression wrinkles”). WebExtrinsic ageing refers to factors acting upon the body from outside forces i.e. sunlight, alcohol, nutrition, pollution and lifestyle. All are choices a person makes and exposure is effected by the incidence and frequency of each. The most attributable cause of extrinsic ageing is UV light 1.
