Topical or Skin Allergies

The skin is the largest organ in the human body, both in terms of weight and surface area. It is a complex organ that serves multiple functions, including:

• Protection
• Sensation
• Thermoregulation
• Vitamin D synthesis.

The skin is made up of three layers: the epidermis, the dermis, and the hypodermis.

The epidermis is the outermost layer of the skin and is responsible for protecting the body from environmental damage and preventing water loss. The dermis is the middle layer of the skin and contains hair follicles, sweat glands, and nerve endings. It also provides structural support to the skin. The hypodermis is the innermost layer of the skin and contains adipose tissue, which provides insulation and cushioning for the body.

The skin also contains various types of cells, including keratinocytes, melanocytes, and immune cells. Keratinocytes produce keratin, a tough protein that helps to make the skin waterproof and resistant to damage. Melanocytes produce melanin, the pigment that gives skin its color and protects it from UV radiation. Immune cells such as T-cells and dendritic cells help to protect the skin from infections and other foreign invaders.

Overall, the skin plays a vital role in maintaining the health and well-being of the body, and it is important to take good care of the skin to promote overall health. This includes protecting the skin from UV radiation, keeping it clean and moisturized, and avoiding exposure to harmful chemicals and environmental toxins.

What are Topical Allergies?

Topical Allergies are a type of allergic reaction that occurs when the skin comes into contact with an allergen. The allergen can be anything that triggers an immune response, such as certain chemicals, plants, or metals. When the skin is exposed to the allergen, it may become red, itchy, and inflamed.

An allergic reaction happens when the immune system has an unusual reaction to a harmless substance. The job of immune system cells is to find foreign substances, such as viruses and bacteria, and get rid of them. Normally, this response protects us from dangerous diseases.

People with skin allergies have over-sensitive immune systems. They can develop allergic skin rashes and other conditions due to proteins found in food, pollen, latex, drugs or other things. The substances that cause allergic reactions are allergens.

A Few Common Types of Skin Allergies:

• Eczema (atopic dermatitis)
  Eczema is a condition where your skin becomes dry and itchy too easily, leading to allergies and inflammation. Atopic dermatitis (AD) is the most common type of eczema. “Atopic” means the tendency to develop allergies. “Dermatitis” means inflammation of the skin.
• Contact dermatitis (irritant and allergic)
  Contact dermatitis is one type of an allergic skin condition. Dermatitis means “inflammation of the skin.” Dermatitis has many causes, including chemicals, soaps, wet diapers, and other substances. Irritants and allergies cause contact dermatitis.
• Hives (urticaria)
  Hives are raised bumps, called welts or wheals, on the skin. Hives can be small or large and can occur anywhere on the body. Hives are itchy. Hives can occur due to an acute allergic reaction to an allergen. Hives can be one sign of an allergic reaction or hives can be one of many signs of an allergic reaction. Hives can occur during severe allergic reactions known as anaphylaxis [anna-fih-LACK-sis].
• Swelling (angioedema)
  
  Angioedema or swelling is an excessive collection of body fluids in the skin, which causes swelling. An allergic reaction can cause angioedema.

   

  Angioedema can happen along with hives. A common location where angioedema can occur is around the eyes, lips, and face. Angioedema can also occur on other parts of the body, even in the throat. Angioedema of the throat can cause breathing difficulty. Angioedema of the throat is an allergic emergency. It requires immediate treatment with a medicine called epinephrine [ep-uh-NEF-rin].

What Causes Topical/Skin Allergies?

Allergic skin conditions can occur after exposure to different allergens, including:

• Latex, pet dander, or poison ivy
• Cold or hot temperatures
• Pollen
• Sunlight
• Water
• Food
• Insects
• Drugs
• Chemicals
