Your skin is the window to your body that reveals the stories of your life. From acne breakouts during your teenage years to the radiant glow of pregnancy and the sunspots of aging, both your age and your health are reflected in your skin. Skin has many functions, making it the ultimate multitasker of the human body. Its most important role is being the first line of defense between our bodies and the outside world, protecting us from bacteria, viruses, and pollution and chemical substances that we encounter in the workplace and at home. Skin regulates body temperature, maintains fluid balance, and controls moisture loss. It also acts as a barrier and shock absorber, recognizes pain sensations to alert us to danger, and protects us against the sun's harmful ultaviolet (UV) rays. External influencers such as unprotected sun exposure and washing too frequently or with water that is too hot can damage skin. An unhealthful diet, stress, a lack of sleep, not enough exercise, dehydration, smoking, and particular medications can all impact the skin's ability to operate as an effective protective barrier.
