Your skin is amazing. It is the largest organ in your body, and it grows with you from birth to adulthood. It allows you to feel a wide range of sensations, and it protects you from a variety of harm. In addition to providing protection from physical damage, your skin also helps keep out germs and bacteria.
It triggers your immune system when germs do manage to make their way through your skin. Plus, skin helps regulate your body temperature and it synthesizes chemicals (like Vitamin D) that provide your body with the nutrients it needs.
Learning how skin works will help you protect and care for it, no matter what your age.
