Skin is composed of three layers: the epidermis (outer layer), dermis (middle layer) and hypodermis (innermost layer).
The epidermis, protects our skin from infection. It is continually making new, and shedding old, skin cells.
The dermis is full of collagen and gives skin its firmness. It helps us feel sensations such as heat, cold and pain.
The hypodermis is made up of fat and connective tissue. It’s what connects our skin to the bone and muscle beneath it.
Our skin is covered in pores, which, as well as being the home to hair follicles, allow sweat and sebum (natural oils) from the sebaceous glands to travel up to the skin’s surface. This allows the skin to hydrate itself.³
Why is skin so important?
The skin is the largest organ in the human body. As well as performing a number of functions that are vital to health, such as temperature regulation and insulation, skin plays a key role in preventing water loss and protecting us against bacteria that cause disease.
