epidermis
The stratum corneum is the outermost layer of the epidermis and is avascular, meaning it lacks blood vessels. This layer is made up of dead skin cells that provide a protective barrier for the underlying layers of skin.
The stratum corneum, the outermost layer of the epidermis, is avascular since it is composed of dead cells that lack blood vessels. This layer acts as a barrier to protect the skin and underlying tissues.
Yes, the epidermis itself is avascular, because the cells of the epidermis are not alive. The dermis layer of skin however, relies on blood vessels.
The term "avascular" actually means lacking in blood vessels. What we call "skin" is actually layers of epithelial tissue, all of which is avascular. So, I suppose all parts of the skin are avascular, but epithelial tissue doe lie upon a layer of vascular connective tissue.
No, hemoglobin is found predominantly in blood. The stratum corneum is avascular, and hemoglobin is not predominant in this skin layer.
Epidermis
The epidermis of the skin has no blood supply.
Avascular tissue is that which does not contain blood vessels or lymphatics. Examples include: The epithelial layer of the skin, cartilage, and the cornea and lens of the eye. There are some types of connective tissue that are composed of elastic fibers that are avascular, too.
The papillary layer of the dermis is made up of areolar connective tissue.
The thinner outer layer of skin is called the epidermis. It serves as the body's first line of defense against environmental factors and is composed primarily of keratinocytes, which produce the protein keratin. The epidermis is avascular, meaning it does not contain blood vessels, and relies on the underlying dermis for nutrients and support.

The dermis is the vascular layer of your skin.
