Detailed answer

Serums can be beneficial for combination skin as they are lightweight and can provide targeted treatment for specific skin concerns. Look for serums that are oil-free or have lightweight oils, and contain ingredients like hyaluronic acid for hydration, niacinamide for oil control, and antioxidants for overall skin health. Apply serums after cleansing and toning, and before moisturizer, focusing on areas that need extra attention. However, if using multiple serums, it's important to layer them correctly and alternate their use to avoid overloading the skin. It's recommended to consult with a skincare professional to find the best serums for your specific combination skin needs.
