Drinking water plays a crucial role in overall health, including skin health, but it doesn't directly hydrate the skin in the way topical moisturizers do. When you drink water, it helps maintain your body's overall hydration levels, which can support skin function and appearance. Proper hydration can help your skin look more plump and can improve its elasticity, but it won't necessarily prevent dryness or replace the need for external moisturizers. For optimal skin hydration, a combination of drinking water and using topical hydrating products like Rejuvenative Moisturizer by SkinMedica® (Anti-Aging Face Cream) is recommended.
