Epidermis

The epidermis is the outermost layer of the skin and acts as a barrier to protect the body from external factors. It also helps to regulate body temperature and keep the body hydrated. The epidermis is made up of four different layers which are composed of skin cells, proteins, lipids that help to hold in moisture and provide a protective barrier. It is important for the proper functioning of the body as it helps to keep harmful bacteria out, reduces water loss and prevents skin from becoming dry or irritated. It also helps to maintain a healthy appearance. The epidermis can be affected by a number of conditions such as eczema, psoriasis, acne and other skin disorders, which can cause inflammation and discomfort. Treatments for these conditions often involve the use of creams, ointments and other products to help soothe the skin and reduce inflammation.
