Detailed answer

Serums can be effective in reducing the appearance of fine lines and wrinkles. They are typically formulated with active ingredients like retinol, hyaluronic acid, peptides, and antioxidants. These ingredients can stimulate collagen production, improve skin elasticity, and provide hydration. Serums are generally lightweight and easily absorbed, allowing the active ingredients to penetrate deeper into the skin. Regular use of serums can result in smoother, firmer, and more youthful-looking skin.
