What is the main benefit of using serums in skin care?

1. To provide a heavy layer of moisture

2. To contain concentrated active ingredients

3. To act as a sunscreen

4. To remove makeup effectively

The correct answer is: To contain concentrated active ingredients

The main benefit of using serums in skin care is that they contain concentrated active ingredients. Serums are typically formulated with a higher concentration of beneficial compounds such as vitamins, antioxidants, peptides, and hyaluronic acid, which can penetrate the skin more effectively than thicker creams or lotions. This concentrated formulation allows serums to target specific skin concerns, such as fine lines, dark spots, and uneven texture, delivering more potent results with smaller amounts of product. In contrast, while some options like providing moisture are important for skin care, serums are not designed primarily as moisturizers; instead, they complement moisturizers by delivering potent actives. Options related to acting as sunscreen or removing makeup don't align with the primary purpose of serums, which is to enhance skin health through targeted treatment. By focusing on the concentration of active ingredients, serums offer a powerful addition to any skincare routine.
