Differences between Sebaceous and Sweat Glands

Sebaceous and sweat glands are two different types of exocrine glands. Sebaceous glands secrete sebum, while sweat glands secrete sweat. Although both types of glands have a similar purpose, there are some key differences between them. This article will discuss the differences between sebaceous and sweat glands, including their structure, function, and what happens when they malfunction.

What is Sebaceous Gland?

Sebaceous glands are small, rounded structures that are found in the skin. These glands produce sebum, an oily substance that lubricates and waterproofs the skin. The sebum is released into ducts that open onto the surface of the skin. Sebaceous glands are most commonly found in areas where there is a high concentration of hair follicles, such as the scalp, face, and pubic region. In some cases, Sebaceous glands can become enlarged and produce a greater amount of sebum. This can lead to conditions such as acne or seborrhea. Sebaceous glands are also a potential site for the development of skin cancer. However, this is relatively rare.

What is Sweat Gland?

Sweat glands are small tubes in your skin that release sweat. Sweat is mostly water with a small amount of salt, red blood cells, and other chemicals. There are two types of sweat glands: eccrine glands and apocrine glands.

  • Eccrine sweat glands are spread over most of your body and open directly onto the surface of your skin. Apocrine sweat glands are found in specific areas, such as your armpits and groin.
  • Sweat helps regulate your body temperature by cooling you off when you’re hot. It also gets rid of waste products, such as salt and toxins. Sweating too much or too little can be a sign of a health problem. sweating can also be caused by anxiety, certain foods or drinks, hot weather, or strenuous exercise.
  • If you have excessive sweating that’s interfering with your daily life, you may have a condition called hyperhidrosis. Treatment for hyperhidrosis may include antiperspirants, Botox injections, prescription medications, or surgery. Sweat gland removal is also an option for people who want to permanently reduce sweating in a particular area. However, this procedure can cause scarring and numbness.

Differences between Sebaceous and Sweat Glands

Sebaceous glands are found in the dermis of the skin and secrete an oily substance called sebum. Sebum helps to lubricate and waterproof the skin. Sweat glands, on the other hand, are found in the epidermis and produce a watery substance called sweat. Sweat helps to cool the body by evaporation. Both types of glands are controlled by the sympathetic nervous system. Sebaceous glands are most prevalent on the face, chest, and back, while sweat glands are more widespread throughout the body.


Sebaceous and sweat glands both have an important role in our body, but they differ in their functions. Sebaceous glands secrete sebum which helps keep our skin soft and hydrated, while sweat glands help to regulate our body temperature by releasing sweat. Knowing the differences between these two types of glands can help you better understand your own body and how it works.
