The human skin is composed of three major layers: the epidermis, dermis, and hypodermis (or subcutis). These three main layers encompass a total of seven distinct layers when broken down in detail.
- The epidermis (outermost layer) has five layers: stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale.
- Beneath the epidermis is the dermis , which has two layers: the papillary layer and the reticular layer.
- Below the dermis lies the hypodermis (subcutis), primarily composed of fat and connective tissue.
So, while there are three primary skin layers overall, these include seven specific sublayers in total.
