Which layer of skin is responsible for providing nutrients?

The dermis is the layer of skin primarily responsible for providing nutrients. This layer contains a rich supply of blood vessels that deliver essential nutrients and oxygen to the skin cells. Additionally, the dermis houses important structures such as hair follicles, sweat glands, and connective tissue, all of which contribute to skin health and nourishment.

In contrast, the epidermis, while it serves as a protective barrier, does not contain blood vessels; therefore, it relies on the dermis for nutrients and oxygen. The hypodermis, which is located beneath the dermis, primarily consists of fat and connective tissue and plays a role in insulation and cushioning, rather than directly providing nutrients to the skin. The stratum corneum is the outermost layer of the epidermis and functions mainly in protection and barrier formation, without any nutrient delivery capabilities.
