Detailed answer

Dark spots, also known as hyperpigmentation, are a result of excess melanin production in the skin. Dehydration, on the other hand, refers to a lack of water in the body. While dehydration can affect the overall health and appearance of the skin, it is not a direct cause of dark spots. However, dehydration can contribute to dullness and uneven skin tone, which may make dark spots more noticeable. It is important to maintain proper hydration by drinking enough water and using moisturizers to keep the skin healthy and minimize the appearance of dark spots.
