Common Types of Skin Rashes
There are several types of skin rashes, each with unique features. Below are some of the most common types:
- Contact Dermatitis: This rash occurs when the skin comes into contact with an irritant or allergen. It typically presents as red, itchy patches that may blister or ooze.
- Atopic Dermatitis (Eczema): A chronic condition characterized by dry, itchy, and inflamed skin. It often affects children but can persist into adulthood.
- Psoriasis: An autoimmune condition that results in thick, scaly patches on the skin. It commonly affects the elbows, knees, and scalp.
- Hives (Urticaria): Raised, itchy welts that appear suddenly and can be triggered by allergens, stress, or infections.
- Heat Rash: Also known as prickly heat, this rash occurs when sweat ducts become blocked, leading to small, itchy bumps.
