Detailed answer

As we age, various factors contribute to skin dullness. One of the primary reasons is a decrease in cell turnover rate, which leads to a buildup of dead skin cells on the surface. Additionally, aging skin experiences a decline in collagen and elastin production, resulting in a loss of skin elasticity and radiance. Increased melanin production may also contribute to skin dullness, as it can lead to uneven skin tone and the appearance of dark spots. Exposure to environmental factors such as pollution and UV radiation further accelerates the aging process and contributes to skin dullness. Overall, the natural aging process combined with external influences contribute to skin dullness over time.
