Studies show how human skin, like all other organs, undergoes chronological skin aging. In addition, skin is in direct contact with the environment, which leads to environmental damage. The first and main environmental factor that causes human skin aging is UV irradiation from the sun. This process is called photoaging, which, like chronological aging, is a cumulative process. While chronological aging depends on the passage of time per se, photoaging depends primarily on the degree of sun exposure and skin pigment. People living outdoor lifestyles, in sunny climates, and are lightly pigmented will experience the greatest degree of photoaging. In the last years substantial progress has been made in understanding cellular and molecular mechanisms leading to chronological aging and photoaging. These processes share fundamental molecular pathways and this new discovery provides exciting new opportunities for the development of new anti-aging products and treatments. Cosmeceutics follows these studies and draws inspiration for its new projects.
