The skin plays a critical role in protecting overall health by serving as the body’s first line of defense against external threats. As the largest organ, it acts as a barrier to pathogens, harmful substances, and physical injuries. The skin also helps regulate body temperature and ensures hydration. Additionally, it produces vitamin D when exposed to sunlight, important for bone health and immune function. Maintaining healthy skin through proper skincare, hydration, and nutrition is essential for overall health and wellness.
