On which part of the body are sebaceous glands not found?

Sebaceous glands, which are responsible for producing sebum to lubricate the skin and hair, are not found on the palms of the hands or the soles of the feet. This is a distinctive characteristic of these two areas. The presence of sebaceous glands contributes to the functioning of the skin on most other areas of the body, including the back, face, and scalp, where they help maintain moisture and provide a protective barrier.

In contrast, the palms and soles have different types of skin that do not require these glands to function effectively. Their specialized structure is adapted to withstand abrasion and friction, making the absence of sebaceous glands in these regions suitable for their specific functions. This anatomical arrangement supports the integrity and resilience of the skin on the palms and soles, which are often exposed to various mechanical stresses.
