What is a serum used for ?

A serum is a liquid cosmetic product intended to be applied to the skin to improve its appearance. Serums often contain a high concentration of active ingredients such as vitamins, antioxidants, and hyaluronic acids, which are designed to target specific skin concerns, such as wrinkles, dryness, dark spots, and inflammation. Serums can be used alone or under moisturizer to help improve skin's texture and appearance. They are often lighter than creams and penetrate deeper into the skin to deliver faster, more visible results. It's important to choose a serum that's right for your skin type and skincare needs, and follow the directions for use provided for best results.
