Detailed answer

Night creams can potentially help with dark knuckles by providing moisturization and nourishment to the skin. They may contain ingredients like hyaluronic acid, vitamin C, kojic acid, or niacinamide that can help lighten hyperpigmentation. However, it is important to note that the effectiveness of night creams for dark knuckles can vary based on individual skin type and the underlying cause of the darkening. It is recommended to consult with a dermatologist to determine the best course of action for addressing dark knuckles.
