What is a primary benefit of using serums in a skincare routine?

• A. They provide a thick barrier on the skin
• B. They deliver concentrated active ingredients
• C. They remove makeup effectively
• D. They offer sun protection

Answer: (B)

The primary benefit of using serums in a skincare routine lies in their ability to deliver concentrated active ingredients directly to the skin. Serums typically have a lightweight formulation that allows for deeper penetration compared to other skincare products, such as creams or lotions. This concentration of active ingredients—such as vitamins, antioxidants, peptides, and hyaluronic acid—targets specific skin concerns effectively, such as hydration, age-related changes, or pigmentation. The other options present benefits that are not typically associated with serums. For instance, while some products may provide a barrier, serums are less about creating a thick layer and more focused on delivering potent ingredients. Additionally, serums are not primarily designed for makeup removal, nor are they a substitute for broad-spectrum sunscreens, which are specifically formulated to protect against UV radiation. Thus, the unique role of serums in enhancing skincare effectiveness makes their ability to deliver concentrated active ingredients their standout benefit.
