Detailed answer

Night creams can help improve the overall condition of the skin on the arms, including sagging. These creams are formulated with ingredients that help to hydrate, nourish, and firm the skin. They may contain ingredients like retinol, peptides, and hyaluronic acid, which can promote collagen production and increase skin elasticity. However, it's important to note that night creams alone may not provide dramatic results for sagging skin. A comprehensive skincare routine that includes regular exfoliation, moisturizing, and targeted exercises or treatments for sagging may be more effective. Consult with a skincare professional for personalized advice and recommendations.
