Detailed answer

Night creams are typically formulated to address facial skin concerns such as hydration, rejuvenation, and repairing damaged skin. They are generally not specifically designed to target sun damage on the arms. For arm sun damage, it is recommended to use sunscreen with a high SPF during the day to protect against further damage. In addition, using a dedicated body lotion or serum with ingredients like antioxidants, vitamin C, or retinol can help to improve the appearance of sun-damaged skin over time. However, consulting with a dermatologist is crucial to determine the best treatment plan for individual needs.
