About

If you’re stuck with itchy, stubborn rashes or eczema that keeps coming back, I get how annoying it is. Especially on the hands - it’s tough to hide and even tougher to treat when you don’t know what’s causing it. You’ve probably tried all the trending creams and home ideas, but nothing sticks for long.

What Makes My Approach Different

I believe every rash is your skin trying to say something. Instead of just guessing, I focus on real answers. Skin allergy diagnosis isn’t about following the latest reel hacks - it’s about understanding exactly what’s setting off your skin. That’s why I rely on a proper eczema patch test to go beyond surface-level fixes.

What to Expect

  • We use the ISS Patch Test, a simple way to check for common triggers behind your flare-ups.
  • The patch goes on your back, stays for 48 hours while you live your normal life.
  • After two days, you come back, and I check each spot for reactions.
  • You leave knowing which stuff to avoid, so you’re not just shooting in the dark anymore.

Who Should Consider This?

If your eczema or dermatitis is stubborn, or you keep getting dry, itchy skin (especially on your hands), this can really help. It’s also useful if you want to start identifying dermatitis triggers for good.

One Thing to Know

No shortcuts here. I always start with a proper consultation - illa (no) exceptions. That’s the only way I can be sure this test will actually help you, not just give you another confusing report. I’m here to help you get some real clarity, not just tick a box.
