They represent between 80 and 90% of the cells in the epidermis, and they are responsible for producing the keratin that, together with epidermal lipids, holds the cells together and provides the skin with its waterproof properties. They also protect against the invasion of germs and UV radiation. They originate in the lower layer of the epidermis and move upward through its layers until they shed. They have a life cycle of approximately 28 days.

These cells make up only 3-5% of the epidermis and are responsible for recognizing antigens, substances that trigger antibody production and a possible immune response. Furthermore, Langerhans cells are capable of modulating the skin's reaction to infections and inflammation.

The main function of these cells is the production of melanin, a substance that plays an important role in protecting against solar radiation. They make up 5% of our skin and are responsible for both skin and hair color, as well as for various types of cutaneous hyperpigmentation (dark spots) and hypopigmentation (white spots).

Merkel cells are in contact with nerve endings, so they may be involved in the perception of mechanical stimuli, such as touch. Less than 0.1% of our skin's composition corresponds to these cells, although they are more abundant in areas of intense perception, such as the finger pulp.

Blood vessels are structures belonging to the circulatory system responsible for carrying the blood pumped by the heart. They are responsible for maintaining the proper functioning of both the dermis and the epidermis by transporting nutrients and oxygen to them, and removing waste from the

It is a cavity that extends from the epidermis to the dermis, reaching the hypodermis in the case of terminal hair (not vellus). Hair growth occurs in it, due to its high concentration of stem cells.

In the epidermis, we find two types of glands: sweat glands and sebaceous glands. The former are responsible for excreting sweat to both eliminate toxins and regulate body temperature. The latter are responsible for secreting oils which, together with sweat, form the skin's hydrolipidic barrier.

These are small dermal “protrusions” in the epidermis that contain clusters of blood vessels. They facilitate the passage of nutrients and oxygen to the deeper layers of the epidermis and also determine the formation of fingerprints.

They are the main cells of the dermis and are responsible for the synthesis of collagen, elastin, and hyaluronic acid, among other substances, and for maintaining the proper composition of the extracellular matrix. Collagen and elastin are structural proteins responsible for giving the skin certain qualities: collagen provides firmness, while elastin provides elasticity. Hyaluronic acid is a glycosaminoglycan responsible for maintaining the skin's necessary hydration level.

These are receptors that, in addition to detecting touch and pressure stimuli, are capable of indicating to the brain the exact location where the contact was received. They are also found in the epidermis and are concentrated in areas with greater sensitivity.

They are mechanoreceptors located deep within the dermis. They are capable of providing instantaneous information about vibrations, touch, and pressure.

Composed mainly of nerve endings and Merkel cells. They are receptors that give the skin the ability to perceive texture and pressure. They are concentrated in the fingertips.

These corpuscles are responsible for thermal sensations, cold and heat, and pressure. They are composed of intertwined networks of nerve fibers and are covered by connective tissue.

Nerve endings found in the dermis and epidermis responsible for transmitting sensations of pain.
