Skin varies in thickness and texture on different parts of the body, depending on its specific function. Skin is composed of two main layers. The Epidermis and the Dermis.

Epidermis
The surface, or top layer of the skin. The Epidermis reflects the condition of the skin and its degree of dryness and oiliness.

Dermis
Just below the Epidermis, the Dermis provides nourishment for the Epidermis and contains cells which produce protein tissues. These tissues give strength and elasticity to the skin. The Dermis contains blood vessels, nerves, sebaceous and sweat glands, hair follicles and lymph vessels. If the Dermis is damaged, permanent scarring can result.

Sebaceous Glands
They are found in the Dermis and help determine skin type. They secrete sebum, the substance which keeps skin soft and supple. Over-active sebacceous glands cause oily skin. When these glands are under-active, the skin is dry. Common skin disturbances such as acne often result when the sebaceous glands produce too much sebum. Bacteria can then cause inflammation, resulting in blemishes.

Subcutaneous Tissue
Also known as hypodermis, is a soft and protective under-layer which cushions the Dermis and supports the skin. This tissue is practically non-existent around the eyes, which is why this area is so delicate.
