What is skin made up of?

The skin is made of two layers. The outer layer, which is the epidermis, is made up of cells that mainly seal and protect the skin. The inner layer, called the dermis, is where the blood vessels, hair roots and different glands reside. There are also various specialized cells that do different things, such as give color or provide protection against infections.

Skin isn’t just skin, as in a collection of one type of cell. Much to the contrary, skin holds an array of compounds so it can do its job. These include proteins, amino acids, water, vitamins, trace minerals, antioxidants, fats and sugar. In addition to protecting you against foreign invaders from the outside world, it also must protect itself by keeping its structures intact, hydrated and healthy. It’s a hungry and thirsty machine that needs more and more input and maintenance as you age because, like any machine, it becomes more inefficient and less reliable with time and constant use.
