#Coloring page layers of the skin skin#
Sebum is an oily substance that keeps the skin moist and soft and acts as a barrier against foreign substances.

The dermis is connected to the epidermis and is made of collagen (a type of connective tissue), which gives the skin its flexibility and strength. What is the function of the dermis layer? Melanocytes produce melanin, which is a natural pigment responsible for the color of the skin. Keratinocytes also produce protein, keratin, and lipids these act as a protective barrier. The cells found in this layer are constantly producing keratinocytes, which play an important role in the formation of Vitamin D with exposure to sunlight.This is the deepest layer of the epidermis.Stratum spinosum (also known as a prickle cell layer): This layer contains dendritic cells, which are the skin’s first line defenders. Stratum granulosum: The chemicals (glycolipids) secreted in this layer keep the skin cells glued to each other. Stratum lucidum: This thin clear layer is only present in the thicker skin (palms and soles). This layer plays the first line of defense against external agents.
