Detailed answer

Environmental toxins, such as air pollution, UV radiation, and cigarette smoke, have detrimental effects on aging skin. They can lead to increased production of free radicals, which cause oxidative stress and damage the skin's collagen and elastin fibers. This results in the formation of wrinkles, fine lines, and sagging skin. These toxins can also disrupt the skin's natural barrier function, leading to dehydration and increased sensitivity. Moreover, they can cause inflammation and contribute to the development of age spots and uneven skin tone. Therefore, protecting the skin from environmental toxins is essential to maintain its youthful appearance and overall health.
