Detailed answer

Using a serum in the morning and at night can provide your skin with continuous benefits. In the morning, a serum can help protect your skin from environmental factors like pollution and UV rays while providing hydration and antioxidants. It can also create a smooth base for makeup application. At night, a serum can help repair and rejuvenate your skin as it undergoes its natural repair process during sleep. It can deliver active ingredients that target specific concerns such as fine lines, wrinkles, or hyperpigmentation. However, it is important to choose a serum that suits your skin type and concerns, and remember to follow it up with a moisturizer for optimal hydration.
