Protecting the skin from pollution is becoming increasingly important for users concerned about its effects. In urban environments, pollutants from transportation, cigarette smoke, and industrial activities introduce harmful substances, microparticles, and gases that settle on the skin. When these pollutants come into contact with the skin, they generate oxidative stress by releasing free radicals. These free radicals trigger specific metabolic pathways that produce inflammatory cytokines and damage cell components. Consequently, the skin can become irritated, and the aging process may accelerate. This results in a dull, grey complexion, early onset of wrinkles, and a loss of skin firmness and youthful appearance.
