Detailed answer

Face masks can be beneficial for reducing the appearance of smile lines due to their ability to provide hydration and promote plumpness in the skin. Most face masks contain ingredients like hyaluronic acid, glycerin, and antioxidants that can help attract and retain moisture, leading to a temporary smoothing effect on smile lines. These masks typically work by creating a barrier on the skin's surface, preventing water loss and allowing the ingredients to penetrate deeper into the epidermis. However, it is important to note that the effects of face masks on smile lines are temporary, and continued use is required to maintain the results. For more long-term and significant reduction in smile lines, other treatments like professional dermal fillers or cosmetic procedures may be recommended.
