Sebaceous Glands vs. Sweat Glands: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on October 28, 2023
Sebaceous glands produce sebum (oil) to lubricate the skin and hair, while sweat glands produce sweat to regulate body temperature.
Key Differences
Sebaceous glands are found in the skin and are responsible for producing sebum, an oily substance. Sweat glands, on the other hand, produce sweat which primarily aids in thermoregulation.
Sebaceous glands are predominantly found associated with hair follicles, releasing sebum onto the hair and skin surface. Conversely, sweat glands open directly onto the skin’s surface or into hair follicles.
The secretion from sebaceous glands, sebum, helps maintain skin and hair moisturized. In contrast, the primary function of sweat from sweat glands is to cool down the body through evaporation.
When sebaceous glands become overactive or blocked, it can lead to conditions like acne. In contrast, malfunctioning sweat glands can lead to disorders like hyperhidrosis or anhidrosis, where there is excessive or insufficient sweating, respectively.
Both sebaceous glands and sweat glands play crucial roles in skin health. While sebaceous glands contribute to the skin's natural barrier and protection, sweat glands aid in the elimination of toxins and body temperature regulation.

Sebaceous Glands and Sweat Glands Definitions
Sebaceous Glands
Sebaceous glands can become blocked, leading to acne.
When sebaceous glands are overactive, it can result in oily skin.
Sweat Glands
Sweat glands eliminate waste and toxins from the body.
By sweating, sweat glands play a role in detoxifying the system.
Sebaceous Glands
Sebaceous glands are predominantly found on the face and scalp.
The density of sebaceous glands is higher on the forehead and chin.
Sweat Glands
Sweat glands are responsible for producing sweat in the skin.
During a workout, sweat glands work overtime to cool the body down.
Sebaceous Glands
Sebaceous glands are oil-producing glands in the skin.
For healthy skin, it's essential for the sebaceous glands to function properly.
Sweat Glands
Sweat glands can be eccrine or apocrine based on their function and location.
The armpits have a higher concentration of apocrine sweat glands.
Sebaceous Glands
Sebaceous glands release sebum onto hair and skin.
The sebaceous glands ensure the skin remains moisturized by secreting sebum.
Sweat Glands
Sweat glands are activated by various stimuli, including heat and emotions.
When nervous, our sweat glands can produce more sweat.
Sebaceous Glands
Sebaceous glands play a role in skin's natural barrier.
Without sebaceous glands, our skin would be dry and unprotected.
