The human skin is the largest organ in the human body. Besides deciding your beauty quotient, your skin is a great barrier working 24/7, protecting you from a variety of elements. Made with a combination of cells, fibers, and extracellular matrix, the skin has different layers and each layer has different functions if you are aiming to achieve a healthy skin soon, you must first understand the layers and stricture of the skin.

How many Layers does Human Skin have?

Human skin is comprised of three layers:

  • Epidermis
  • Dermis
  • Hypodermis

Each layer of the skin has its distinctive function and contributes towards the overall health of the skin.

Functions of Different Skin Layers:


The outermost layer of the skin is called Epidermis. From preventing harmful bacteria, viruses, and any other foreign elements from entering inside the skin to preventing water loss, the epidermis performs a lot of functions. It is also the key decisive factor of your skin’s colors as it possesses melanocytes.

Epidermis further has different layers, including:

  1. Stratum Basale
  2. Stratum Spinosum
  3. Stratum Granulosum
  4. Stratum Lucidum
  5. Stratum Corneum


The Dermis is the second layer of skin. It lies under the dermis and contains collagen, elastin, blood vessels and hair follicles. It also houses the sweat glands which releases sweat that flushes the toxin out of the body. Plus this layer is what provides the human with a sense of touch. Various layers that constitute dermis include:

  1. Papillary Dermis
  2. Reticular Dermis


Also known as Subcutaneous Tissue, Hypodermis is the innermost layer of skin. It is made of well-vascularized, loose connective tissue and adipose tissue. It also houses many muscle, tendon, ligament, joint capsule and bone right underneath of it. It works towards maintaining the temperature of the body and also absorbs any kind of shock exerted on the body. It can be described as the connective layer between the dermis and the bones and muscles.

Taking care of your skin is very important. Now that you know the anatomy of the skin, it might be a little easier for you to understand your skin condition. However, for the best care and healthy skin, you must consult with an experienced dermatologist and seek advice.
