Allergic reactions are immune responses triggered by exposure to allergens, substances the body recognizes as harmful. When it comes in contact with an allergen, your immune system creates antibodies. These antibodies release histamines and other chemicals in the body, triggering symptoms of an allergic reaction. This could include itchiness or rashes.
Dermatitis is an inflammation of the skin, often due to factors such as allergens, irritants, environmental triggers, or underlying health conditions. This inflammatory response typically appears as redness, itching, swelling, blisters, or lesions on the skin (in severe cases).
Contact dermatitis is caused when you come into direct contact with irritants or allergens. Symptoms include red, itchy rashes accompanied by swelling, blistering, or dry, cracked skin. It may be caused by various substances, including chemicals, cosmetics, metals, plants, and certain medications.
Treatment strategies for contact dermatitis focus on relieving symptoms, reducing inflammation, and avoiding triggers.
