The 4 Most Common Skin Diseases and Their Causes


There are hundreds of skin diseases that affect human beings. Unfortunately, the symptoms of the most common skin conditions are similar. Before you start any treatment, you should be sure about what you want to treat. Understanding the difference between them is the only way to avoid medical errors when treating skin diseases.

If you have a skin disease, you should see a dermatologist diagnose and prescribe the best treatment. Taking over the counter drugs to treat skin diseases is not recommended as it may end up worsening the condition. Below are some of the most common skin diseases:

1. Eczema (Atopic dermatitis)

The exact cause of Eczema isn’t yet known, but many researchers believe that it is something to do with genetics, immune system, and environment. In infants, atopic dermatitis can appear on the face. In adults, it appears on the feet, hands, face, and folds and creases of the skin.

Dry and itchy skin with a constant urge to scratch the affected area are the most common symptoms of Eczema. If you suspect that you have Eczema, you should see a dermatologist confirm it. Before seeing your doctor, you can be applying topical steroids on the affected area to lessen the symptoms.

If topical therapy doesn’t help lessen the annoying symptoms, Dupilumab (Regeneron’s Dupixent) injection might help. The Federal Drug Administration (FDA) has cleared its use in treating moderate and severe Eczema symptoms in adults.

2. Acne vulgaris (Acne)

Acne is the most common skin disease in the US. It is a source of anxiety in many teens. They occur when bacteria, oil, or dead skin block the pores of the skin. Hormonal changes are the main trigger of acne in teens.

Acne does not only refer to pimples on the face but also cysts, blackheads, and nodules. Acne can also appear on the chest and back. If you suspect that the pimples on your face are acne, you should see a dermatologist because if left untreated, acne can lead to dark facial spots or permanent scars.

You can use adapalene topical, Amnesteem, Claravis, Tretinoin topical, or Sarecycline to calm the annoying symptoms of acne as you wait to see a dermatologist.

3. Sunburn

For sure, it is easier to prevent sunburn than to treat it. Exposure to Ultraviolet light from the sun is the primary cause of sunburn. Overexposure to sunlight turns your skin red, hot to touch, painful, and may even peel away.

It is hard to tell how much time is too much when it comes to exposure to sunlight. Many people take it as a simple infection, but that is because they don’t know that repeated sunburns, especially in infants, increases the risk for skin cancer later in life.

The first treatment to sunburns is seeking shade and taking a shower with mild soap. You can also apply aloe vera and oil-free skin moisturizers before walking in direct sunlight. Drinking plenty of water to moisturize your skin might also help.

If you have sunburns, you should use ibuprofen to ease the symptoms. It helps stop inflammation and other discomforts.

4. Contact dermatitis

Contact dermatitis is a type of Eczema that occurs when your skin comes into contact with something that can cause skin irritation. Some of the common causes of contact dermatitis include:

  • latex gloves
  • jewelry
  • plants
  • soaps, bleach, and other irritants.

You can control the symptoms of contact dermatitis using topical and oral steroids. A colloidal oatmeal bath might also help calm the annoying symptoms. Contact dermatitis that doesn’t go away after two or three days requires dermatologist attention to determine the cause and prescribe the best treatment.

5. Athlete’s foot

Our feet are prone to fungal infections. Athlete’s foot is a fungal infection that affects the skin of your feet. Some of the symptoms of athlete’s foot include:

  • redness
  • itching
  • cracked skin

Several antifungal topicals might help calm the symptoms of athlete’s foot. Some of the best topicals you should consider using include:

  1. Micatin
  2. Lamisil AT
  3. Lotrimin AF

The symptoms do not disappear immediately after treatment, but if you can see any improvement, you should see a dermatologist for further advice and treatment. Keeping your feet clean and dry is the best way to prevent athlete’s foot infections.
