What is Contact Dermatitis? Understanding Skin Reactions
Contact dermatitis is a common inflammatory skin condition that occurs when the skin comes into direct contact with an irritant or allergen. It leads to redness, itching, swelling, and sometimes blistering or peeling. There are two main types: irritant contact dermatitis, caused by exposure to harsh substances like detergents or chemicals, and allergic contact dermatitis, triggered by an immune reaction to allergens such as nickel, fragrances, or poison ivy. Though not contagious or life-threatening, it can significantly affect comfort, daily activities, and quality of life.
Symptoms of Contact Dermatitis
Recognizing the symptoms early can help prevent the condition from worsening. Common signs include:
- Red Rash: Appears in areas of skin that came into contact with an irritant or allergen.
- Itching or Burning Sensation: Often intense and uncomfortable, sometimes worsening over time.
- Dry, Cracked, or Scaly Skin: Particularly with prolonged or repeated exposure.
- Swelling or Blisters: In more severe cases, the skin may become swollen, ooze fluid, or form blisters.
