What is the main benefit of using a serum in a skincare routine?

1. To deliver concentrated active ingredients

2. To act as a makeup primer

3. To provide sun protection

4. To cleanse the skin

The correct answer is: To deliver concentrated active ingredients

Using a serum in a skincare routine primarily offers the benefit of delivering concentrated active ingredients directly to the skin. Serums typically have a lightweight formula that allows them to penetrate deeper into the skin layers compared to other skincare products, such as creams or moisturizers. This concentrated delivery system means that serums can effectively target specific skin concerns, such as fine lines, hyperpigmentation, or dehydration, by using potent ingredients like antioxidants, peptides, or vitamins. In contrast, while products that act as makeup primers, provide sun protection, or cleanse the skin may play important roles in a skincare regimen, they do not focus on the targeted delivery of active ingredients, which is the defining characteristic and primary benefit of serums. This targeted approach makes serums a valuable addition for those seeking to address particular skin issues in a more effective manner.
