What are three signs of contact dermatitis?

Three primary signs of contact dermatitis are red, irritated skin, itching, and swelling. This common skin condition occurs when your skin reacts to contact with certain substances, leading to a localized rash or irritation.

Key Signs of Contact Dermatitis

Here are the distinct signs you might observe if you have contact dermatitis:

• Red, Irritated Skin:
  The affected skin area often appears visibly red and inflamed. This redness can vary in intensity, from a mild pink to a bright red, and is usually accompanied by a general feeling of irritation or discomfort. It directly corresponds to the area that came into contact with the irritant or allergen.

• Itching:
  One of the most characteristic symptoms, itching, can range from mild to intense. This persistent urge to scratch the affected skin can be very disruptive and is a primary source of discomfort for individuals experiencing contact dermatitis.

• Swelling:
  Inflammation in the affected area often leads to swelling, making the skin appear puffy or raised. This can be localized to the precise point of contact or spread slightly around it, depending on the severity of the reaction and the extent of exposure.

These signs typically appear shortly after exposure to an irritant or allergen, though allergic reactions can sometimes develop hours or even days later.
