An Anti-Aging Serum is a skincare product designed to reduce the visible signs of aging, such as wrinkles, fine lines, and uneven skin tone. These serums often contain active ingredients like retinol, hyaluronic acid, and vitamin C, which help to promote skin renewal, hydration, and collagen production. Typically applied after cleansing and before moisturizing, anti-aging serums are lightweight and easily absorbed into the skin. Regular use can lead to a more youthful appearance by improving skin texture and elasticity, making them a popular choice in many people's skincare routines.
