Thin And Thick Skin: Know The Differences Here

Written by Ramona Sinha

The skin is our body’s first layer of protection against environmental aggressors, pathogens, and diseases. It has different thicknesses across our body – some parts have thick skin, and others have thin skin. The skin has three layers and mainly contains sebaceous glands and hair follicles. The thickness of the layers and their components are different all over the body. Scroll through the article to understand the difference between thick and thin skin.

What Is Thin Skin?

What Is Thin Skin


Thin skin has a thinner epidermis (top layer)and lacks the stratum lucidum layer. The epidermis has total five layers (1):

  •  Stratum basale or Stratum germinativum: It is the deepest layer of the epidermis and contains melanocytes (cells that produce melanin).
  •  Stratum spinosum: It has 8-10 cells layers and contains the dendritic cells (a type of immune cells).
  •  Stratum granulosum: It has 3-5 cell layers and contains the glycolipids that keep the skin cells stuck.
  •  Stratum lucidum: It contains 2-3 cell layers and is only found in thick skin in the soles and palms.
  •  Stratum corneum: It is the uppermost skin layer and has 20-30 cell layers made of keratin and dead keratinocytes (cells that produce keratin).

Thin skin is found all over the body except the hands, arms, and feet. The eye area, especially the eyelids, has the thinnest skin.

Did You Know?

The upper back skin is the thickest (considering the thickness of the dermis) but is considered thin skin as it has a thinner epidermis.

Now, let’s understand what thick skin is.

What Is Thick Skin?

What Is Thick Skin


Unlike thin skin, thick skin has all five epidermis layers and is mainly present in areas that receive the most friction, like the fingertips, palms, and soles. Thick skin is hairless and does not contain sebaceous glands and apocrine sweat glands as it opens in the hair follicle.

Here is a brief overview and comparison between the structure of thin and thick skin.

Has a thin dermis.Has a thick dermis.
Dermal PapillaeHas dermal papillae that consist of mesenchymal cells to regulate hair growth.Has more prominent dermal papillae.
EpidermisHas five layers in the epidermis.Has only four layers in the epidermis.
Sensory ReceptorsHas dense sensory receptors.Has scattered sensory receptors.
Sweat GlandsHas only eccrine sweat glands that release water to cool down skin’s surface.Has both eccrine and apocrine glands (secretes fatty sweat).
Hair FolliclesDoes not have any hair follicles.Has hair follicles.
Sebaceous GlandNo sebaceous glands.Contains sebaceous glands.
Arrector Pili MusclesDoes not contain arrector pili muscles (that causes goosebumps).Has arrector pili muscles.

Apart from these differences, thick and thin skin have different functions.

Thin skin contains:

  •  Hair follicles connected to different glands and muscles help to regulate body temperature and repair wounds (2).
  •  Sebaceous glands produce sebum to keep the skin nourished, moisturized, and protected.
  •  Sweat glands regulate body temperature.

Thick skin:

  •  Prevents damage to areas that are exposed to maximum friction.
  •  Has eccrine sweat glands that help regulate body temperature.

In A Nutshell

The skin is considered thick or thin depending on the thickness of the epidermis. It has a complex structure made of networks of cells, muscles, and nerves to protect the body from pathogens and environmental damage. The different thicknesses across the body parts to maintain different body functions and keep you healthy. While thick skin is found on the palms and feet soles, the rest of the body parts have thin (hairy) skin. We hope this article has helped you understand the differences between thick and thin skin.
