Anti-aging skin care technologies have become increasingly high-tech, targeting specific cellular phenomena. However, as illustrated above, skin aging is the sum of several concurrent aging processes, which differ in aging contribution among individuals. Photoaging has received more attention in research and the media, but is only one aspect of the aging process. Although the rationale for sun protection is widely advocated, people still associate it with occasional holiday exposure.9 Photoaging affects people of the same age and photo-type differently10 and might not become apparent for decades after the initial damage. To ensure good environmental protection, daily skin care products containing a combination of SPF 20+ and a spectrum of antioxidants should be used.
Postmenopausal skin aging is often neglected in the “classical” aging concept, as its impact is difficult to estimate. In women, intrinsic and postmenopausal aging are linked. There is an array of technologies designed to aid skin changes from intrinsic aging or menopause. Examples of actives clinically tested, although on forearms and not facial skin, include c-xyloside, which was shown to repair the DEJ,11 and bifidobacterium-fermented soy milk extract, which improved skin elasticity.12
Skin aging is an interplay of the different types of aging that differs between individuals; the best approach entails the use of multifunctional active ingredients that address more than one type. Also, shifting consumer attitudes toward a more holistic approach to skin health represents the next educational challenge for skin care and beauty brands.
