The epidermis acts as a protective barrier that keeps out harmful viruses, bacteria, and other infectious agents while retaining water and nutrients in the body for use. Unfortunately, the epidermis can be affected by common skin conditions like acne, eczema, melanoma, and dandruff. Therefore, keeping the epidermis healthy is extremely important for your body and overall skin health. Here's how you can keep your epidermis in tip-top shape: (1) Avoid rubbing or scratching irritated skin. (2) Drink the recommended amount of water throughout the day to keep your skin hydrated. (3) Establish a well-rounded skincare routine. (4) Use sunscreen daily, even when it's cloudy outside. (5) Use a mild soap to cleanse your skin and apply a moisturizing cream immediately to seal moisture.
