What's the difference between an allergy vs chemical sensitivity?

A doctor has provided 1 answer

Immune vs Irritant: An allergic reaction involves the immune system reacting to a specific substance and causing symptoms such as rash, itching, hay fever, or asthma. A chemical sensitivity can be an irritant reaction or toxic reaction that causes direct damage to the skin, respiratory system or gastrointestinal system on contact.
