The sebaceous gland is responsible for producing sebum, which is an oily substance that plays a crucial role in waterproofing the skin and maintaining its integrity. Sebum helps to create a barrier on the skin's surface, preventing moisture loss and protecting against environmental factors. The oily nature of sebum also contributes to the overall hydration of the skin, keeping it supple and reducing the likelihood of dryness and irritation. This function is essential for skin health and is particularly important in areas of the body that are more prone to dryness.

In contrast, the apocrine gland primarily produces a thicker, odorous sweat associated with body odor and is often found in specific areas such as the armpits and groin. The eccrine gland, on the other hand, is primarily involved in thermoregulation and secretes a watery sweat that helps cool the body. The sudoriferous gland, which encompasses both eccrine and apocrine glands, also does not produce sebum. Understanding the distinct functions of these glands highlights the specialized role of the sebaceous gland in maintaining healthy skin.
