What is the term for a skin disorder caused by an allergy to the product?

The term for a skin disorder caused by an allergy to a product is best described as contact dermatitis. This specific type of dermatitis occurs when the skin reacts to substances it has come into contact with, resulting in inflammation, redness, and itching. In contrast, dermatitis is a broader term that encompasses various skin inflammation conditions, which can include contact dermatitis but also pertains to other forms that may not necessarily involve an allergen or product.

Psoriasis and eczema are distinct conditions that have different triggers and symptoms. Psoriasis is primarily an autoimmune condition characterized by the rapid buildup of skin cells, leading to scaling and inflammation, while eczema, although sometimes involved with allergic reactions, typically refers to a group of conditions that cause the skin to become inflamed, itchy, and red but does not specifically relate to a reaction from a product.

Therefore, for the specific context of an allergy to a product leading to skin issues, contact dermatitis is the precise term to use.
