Allergy
Skin allergies, also known as allergic contact dermatitis, occur when the skin reacts to substances that it comes into contact with. These substances, known as allergens, can trigger an immune response in some individuals, leading to various symptoms. Skin allergies are common and can be triggered by a wide range of substances, including certain foods, medications, plants, animal dander, insect stings, and chemicals found in personal care products and clothing.

The symptoms of a skin allergy can vary depending on the individual and the allergen involved but generally include:
- Redness: Affected areas of the skin may become red and inflamed.
- Itching: Intense itching is a common symptom of skin allergies.
- Rash: A rash may develop, which can be raised, bumpy, or blistered.
- Swelling: The skin may swell in response to an allergen.
- Dry, cracked skin: In chronic cases, the skin may become dry, cracked, or scaly.
