Which layer of the skin contains hair follicles and sebaceous glands?

The dermis is the layer of skin that contains hair follicles and sebaceous glands. This middle layer is crucial for providing strength, elasticity, and support to the skin. It is composed of connective tissue and is much thicker than the outer layer, the epidermis. Within the dermis, you will find various structures, including hair follicles, which are responsible for hair growth, and sebaceous glands, which secrete sebum (oil) that helps to keep the skin moisturized and protect it from environmental damage.

The hypodermis, while located beneath the dermis, primarily consists of fat and connective tissue and does not contain hair follicles or sebaceous glands. The epidermis is the outermost layer of skin, primarily composed of keratinized epithelial cells, and does not house hair follicles or glands. The stratum corneum is the outermost part of the epidermis, consisting mainly of dead skin cells, serving as a barrier to protect the underlying layers but lacking any associated structures like hair follicles or glands. Thus, the dermis is the correct layer associated with hair follicles and sebaceous glands.
