Hydration plays a crucial role in maintaining skin health as it helps in keeping the skin moisturized, supple, and radiant. Proper hydration ensures that the skin stays plump, improves elasticity, and helps in preventing dryness, flakiness, and premature aging. It also supports the skin's natural barrier function, protecting it from external aggressors such as pollutants and UV radiation. Drinking an adequate amount of water and using hydrating skincare products are essential for healthy and glowing skin.
