Synthetic products can damage the skin barrier which is the defense against environmental aggressors, such as bacteria, pollutants, and UV radiation. When this barrier is damaged, it leads to issues such as dryness, irritation, inflammation, sensitivity, and chronic conditions like eczema. Harsh products can also cause allergic reactions, long-term dryness, or overproduction of oil. Overuse of aggressive exfoliants can increase the risk of fine lines, wrinkles, and uneven skin texture.
