All dermatologists agree that skin aging is a combination of both internal and external factors: Genetic factors lead to natural, endogenous aging, which is characterized by a slowing of cell renewal. This is an irreversible phenomenon. Endogenous aging manifests itself as dry skin and superficial wrinkles, loss of firmness and deep wrinkles on the skin. Exogenous environmental factors accelerate the whole process. Sun exposure is the main cause, combined with smoking and stress. These aggressive agents, which vary from person to person, stimulate the production of free radicals, which are responsible for oxidative stress, which causes cell degeneration. The main consequence of sun exposure is photoaging, a form of premature aging that affects every layer of the skin.
