About this listen
Itchy, blistering skin that won’t go away? Before you blame food, pets, or seasonal allergies, it might be allergic contact dermatitis, a delayed skin reaction caused by everyday products you don’t even realize are touching you.
In this episode of My Allergist Dad, Drew sits down with his dad, Dr. Z, to break down what allergic contact dermatitis actually is, how it’s different from hives or classic allergies, and why antihistamines often don’t help. They share real patient stories involving shampoo, soap, shaving cream, lip balm, jeans buttons, hairdressers, hand sanitizer, and even “all-natural” products that turned out to be the real culprits.
You’ll learn:
The difference between allergic reactions, irritant reactions, and contact dermatitis
Why rashes can show up days after exposure
What patch testing is and how it works
Common ingredients in products like fragrancesfragrances, preservatives, metals, and dyes that cause reactions
Why “natural” doesn’t always mean safe for your skin
If you’ve been itchy, miserable, or bouncing between doctors without answers, this episode might finally explain what your skin has been trying to tell you.
