4 Steps to the Behind-the-Ear Test for Nonenal

Koko Hayashi

It might feel a little awkward. But it’s one of the most honest ways to check your skin.

If you’ve ever rubbed behind your ear and quickly smelled your finger, you’ve already done it. 

That small habit is actually known as the behind-the-ear test, and it’s one of the easiest ways to check for nonenal, often called aging odor.

What Is Nonenal?

Nonenal is a natural scent that can develop as your skin changes over time.

It’s often described as:

  • Slightly oily
  • Faintly musty
  • Lingering even after washing

This isn’t about hygiene. Even with daily showers, this can still happen. It’s simply part of how skin chemistry evolves with age.

Why Check Behind the Ear?

The area behind your ear is one of the first places nonenal tends to appear.

That’s because:

  • It produces natural oils
  • It’s easy to miss when washing
  • Buildup can happen quietly over time

So even if the rest of your skin feels clean, this small spot can reveal more.

How to Do the Test

It only takes a few seconds:

  1. Wash your hands
  2. Dry them completely
  3. Gently rub behind your ear
  4. Smell your finger

If you’re not sure what you’re noticing, try checking your pillowcase or shirt collar. We can get used to our own scent over time, making it harder to recognize right away.

What Actually Helps

This is where it matters.

Most regular soaps make you smell fresh for a while, but they often just cover the odor. To properly deal with nonenal, you need something that helps remove it from the skin.

That’s why many people turn to persimmon-based products like Mirai Clinical Deodorizing Soap Bar.

Why is it different?
