Thin as our skin may be, it is still a complex organ. Have you ever wondered how many layers of skin we have? The answer may surprise you. Overall, we have 3 layers: the epidermis, the dermis (often called the true skin), and the subcutaneous (or hypodermis) layer. Each of the three layers are very complex themselves—the epidermis has 5 layers and the dermis has 2 layers.
This cross section of human skin shows most, but not all, of what is happening inside the .09-2mm of tissue on our body. For instance, look at the size of the epidermis versus the dermis. The epidermis has 5 layers-the stratum corneum, the stratum lucidum (found only in the palms of the hands and the soles of the feet), the stratum granulosum, the stratum spinosum, and the stratum germinativum. The epidermis packs quite a lot into such a small area compared to the two layers in the dermis –the papillary layer and the reticular layer. Below the epidermis and the dermis is the final layer of the skin—the subcutaneous layer. Sometimes, this layer is also called the fatty layer or the subdermis.
Keep an eye out for my next two blogs where I explain exactly what is happening in each layer of the epidermis and dermis.
Don’t forget, keep your skin hydrated and protected from the sun!
