Skin allergies can be caused by a wide range of factors, including contact with irritants or allergens, exposure to sunlight or heat, insect bites, medications, and underlying medical conditions. The following are some common types of skin allergies:
Contact dermatitis: This is a type of skin allergy that occurs when the skin meets a substance that irritates or triggers an allergic reaction, such as poison ivy, nickel, or latex.
Atopic dermatitis: Also known as eczema, this is a chronic skin condition that causes red, itchy, and inflamed skin. It is often triggered by environmental factors such as dust mites, pet dander, or pollen.
Hives: Hives are raised, itchy bumps that can appear anywhere on the body. They are often caused by an allergic reaction to a food, medication, or insect bite.
Angioedema: This is a type of skin swelling that occurs beneath the surface of the skin, often around the eyes and lips. It can be caused by an allergic reaction to food, medication, or insect bites.
Urticaria: This is a skin condition characterized by the sudden appearance of hives and swelling. It can be caused by an allergic reaction to food, medication, or insect bites.
Photoallergic dermatitis: This is a type of skin allergy that occurs when the skin is exposed to sunlight or other sources of ultraviolet light. It can be caused by certain medications, fragrances, or chemicals.
Seborrheic dermatitis: This is a skin condition that causes red, scaly patches on the scalp, face, and other areas of the body. It can be caused by a yeast overgrowth or other factors.
It is important to identify the cause of the skin allergy and avoid exposure to the trigger in order to prevent future allergic reactions. Consultation with a healthcare provider or allergist can be helpful in identifying the underlying cause of a skin allergy.
