Detailed answer

Some face masks may contain ingredients that can strip away the natural oils on the skin's surface, leading to dryness and dullness. Additionally, certain masks can cause inflammation or irritation, which can also contribute to a lackluster appearance. It's important to choose masks that are suitable for your skin type and avoid those with harsh ingredients. Furthermore, overusing face masks or leaving them on for too long can disrupt the skin's moisture balance, causing dullness. Properly hydrating and moisturizing the skin after using a face mask can help restore radiance and vitality.
