Basic Human Skin Structure And Functions – Skin Care

Basic Human Skin Structure And Functions

Human Skin Structure And Functions are quite complex in nature and there is lot understand about it. Skin care is much more than just creams, serums, and exfoliators. Likewise, your skin is not just a convenient layer that covers your entire body. It serves a range of functions that promote survival. Having a greater knowledge of skin mechanisms and interactions on a molecular level is vital to practicing a workable skin care routine.

Biology and Structure Of Human Skin

A glimpse through the microscope reveals the multilayered structure of the skin, as well as the infinitesimal elements within these layers that assist the proper function of the skin.

Functions of The Human Skin

  1. Synthesizes vitamin D;
  2. Regulates body temperature;
  3. Protects the body from injury, chemicals, microbes, and the harmful effects of the sun;
  4. Acts as a sensor, and transmits messages from the environment to the brain;

The Layers of The Human Skin

Human skin is made up of three primary layers and they are known as:

  1. Epidermis: The epidermis is the visible layer of skin. It provides the body with a waterproof barrier and also creates your skin tone through the production of melanin.
  2. Dermis: This layer lies directly beneath the epidermis and contains connective tissue, sweat glands, and hair follicles. The collagen and elastin fibers found in the dermis provide the skin with flexibility. Much of this elasticity is lost as you age, resulting in wrinkles.
  3. Hypodermis: This is the deepest layer of skin, also known as subcutaneous fat. They hypodermis is composed of adipose and connective tissue. The fat found here serves as an insulator and acts as a source of energy for the body.

Essential Structures of Human Skin

  1. Hair follicles: They are embedded in the dermis and occur all over the body, excluding your palms, soles, and lips.
  2. Sebaceous gland: These tiny glands produce a lubricant called sebum which acts as a waterproof barrier that also repels chemicals and germs.
  3. Sweat glands: An average person has more than 2 million sweat glands. The skin produces sweat whenever the body needs to eliminate heat. When sweat reaches the epidermis, it evaporates and cools down the body.
  4. Muscle fibers: These small fibers are attached to each hair follicle. Muscle fibers respond to environmental factors like cold temperatures and threats. Erect muscle fibers are also referred to as “goosebumps.”
  5. Nerves: Nerves are found in the dermis layer of the skin. They detect pain, touch, heat, and cold, then relays this information to the brain.

Human Skin Conditions

The following skin conditions are the most common. They typically result from jeopardized skin health. Most of these can be warded away through proper skin care.

  • Eczema: Also known as dermatitis, eczema results from skin inflammation. The condition typically causes an itchy rash.
  • Rash: Any change in skin appearance can be classified as a rash. Most rashes stem from skin irritation and food allergies. Others result from medical conditions.
  • Psoriasis: This is an autoimmune skin condition that often results in rashes. Psoriasis is characterized by scaly plaques on the skin.
  • Hives: Hives tend to occur suddenly in response to an allergic reaction. Hives are characterized by itchy red patches on the skin.
  • Acne: This is the most common skin condition. Acne is usually a product of unhealthy dietary habits and stress.
  • Rosacea: This is a chronic skin condition that causes a bright red rash. It tends to occur on the face.
  • Cellulitis: An inflamed dermis and subcutaneous tissue may result in cellulitis. It is often a byproduct of infection.
  • Warts: A wart is a virus that infects the skin, causing excessive skin growth.
  • Melanoma: This is a type of skin cancer that is signified as the most harmful. Melanoma results from excessive sun exposure.
  • Actinic keratosis: Too much unprotected sun exposure may result in scaly bumps all over the skin. If left untreated, actinic keratosis may lead to skin cancer
