What is a benefit of water consumption for the skin?

A. Water intake does not directly stimulate oil (sebum) production. Sebum production is regulated by hormones and the activity of sebaceous glands, not hydration levels. Increased water consumption may help skin hydration but does not increase oil production. B. Adequate water consumption helps the body eliminate waste products through the kidneys and urinary system. Proper hydration supports overall metabolic processes and helps maintain healthy skin by promoting toxin removal, reducing the risk of dullness, dryness, and irritation. Well-hydrated skin appears more plump and resilient. C. Water consumption cannot permanently alter pore size. Pores are determined by genetics and skin type. Hydration may improve the skin’s appearance temporarily but does not permanently tighten pores. D. Melanin production, which determines skin pigmentation, is controlled by melanocytes and influenced by factors such as UV exposure and genetics. Water intake does not affect melanin synthesis or pigmentation.
