The skin of an average adult is approximately 18,000 cm2. This measurement accounts for the total surface area of the skin, encompassing all parts of the body.
The thickness of the skin can vary depending on the location on the body. For example, the skin on the back is thicker than the skin on the eyelids. However, the overall surface area remains relatively consistent.
It's important to note that this is an approximate measurement. The actual size of an individual's skin may vary slightly based on their body size and other factors.
