Because what you put ON your body, is as important as what you put IN your body

Skin is the largest organ of your body. Your skin acts to protect your skeleton and other organs, it provides tactile sensations, it helps to control your temperature, it absorbs shock to protect your muscles and internal systems, it produces Vitamin D, acts as a waterproof barrier for your internal organs and structure, and functions as a lubrication. Your skin is your first line of defense against the outside world.
