This week, we dive into allergic reactions and contact dermatitis—two conditions that look similar on the surface but require completely different approaches to diagnose and treat.

We break down the difference between irritant vs. allergic contact dermatitis, why some patients flare from everyday products, and how the immune system can overreact to seemingly harmless ingredients. We also cover patch testing, common allergens like fragrances, preservatives, and metals, and how delayed hypersensitivity reactions actually work.

You’ll learn why allergic reactions aren’t always immediate, why “hypoallergenic” doesn’t always mean safe, and why chronic contact dermatitis patients can suffer for years before getting the right diagnosis. We also discuss treatment options: topical steroids vs. non-steroidal alternatives, barrier repair strategies, and how to help patients identify triggers without overwhelming them.

If you’ve ever wondered why a rash keeps coming back, or why a product “you’ve used forever” suddenly causes a reaction—this episode explains it all.
