Facial serums are lightweight skincare products designed to deliver concentrated active ingredients directly to the skin. They typically contain vitamins, antioxidants, and other beneficial compounds that target specific skin concerns, such as dryness, wrinkles, or acne. Serums are usually applied after cleansing and before moisturizing, allowing for better absorption. These products come in various formulations, catering to different skin types and needs. For example, a hyaluronic acid serum can help hydrate the skin, while a vitamin C serum may brighten the complexion. Regular use of facial serums can enhance overall skin health and appearance.
