Detailed answer

While day creams are designed to provide hydration, protection, and sometimes contain ingredients like SPF for daytime use, night creams are specifically formulated to address the skin's needs during sleep. Night creams are usually richer and more concentrated with ingredients that promote skin repair, regeneration, and moisture retention. If you use a day cream at night, it may not provide the necessary nourishment and benefits that your skin requires during its restorative phase. It's best to use a night cream that is specifically formulated for nighttime use to optimize the benefits for your skin's health and vitality.
