5 persistent myths about period underwear that women still believe in 2026

by Dr. Regina Girgis (physician) & Isabelle Doczy (registered nurse)

Updated: September 1, 2026

"Unhygienic, constantly wet, much too thick – and in any case, it leaks after only a few hours during a heavy period."

It is precisely these prejudices that still prevent many women from even trying period underwear.

And they are not entirely unfounded: many period panties have confirmed exactly these problems for a long time.

But not all period underwear is created equal.

Dr. Regina Girgis and Isabelle Doczy therefore take a close look at the 5 biggest myths – and show why more than 200,000 women now rely on my•mense.

1. "Period underwear is unhygienic and smells"

Probably the most unpleasant thought?

Wearing period panties for hours and eventually smelling something yourself.

Or worse: Others can smell it too.

Particularly with other period underwear manufacturers, simple materials and poor workmanship can cause unpleasant odors to develop more quickly.

my•mense therefore relies on high-quality, tested materials and odor control without biocides.

✅ biocide-free
✅ PFAS-free
✅ OEKO-TEX certified
✅ vegan

And after wearing?

Rinse briefly in cold water, wash, let air dry. Done.

The result: A pair of period panties that you can wear for up to 12 hours, depending on the intensity of your flow – without constantly having to worry about odor and hygiene.

2. "Period underwear is only suitable for light days"

"I have a heavy period – there's no way that will keep me leak-free."

Exactly why many women don't even dare to try period underwear. They assume it wouldn't be an option for a heavy period anyway.

And with other period underwear brands, the absorbency can indeed reach its limits quickly.

At my•mense, it's a different story:

Depending on the style, the panties can hold amounts of fluid equivalent to up to 5 regular tampons or 4 pads.

Additionally, the SafeSide™️ barrier protects against side leaks.

This means:

✅ Fewer changes.

✅ Less planning.

✅ More security.

✅ Even on heavier days.

And if you do want to change while on the go?

Thanks to side fasteners, Ivy can be changed without having to completely remove your pants and shoes.

The truth: Even a heavy period doesn't rule out period underwear. Absorbency and leak protection are what matter.

3. “Period underwear feels like a diaper”

Thick, bulky, and visible under clothing.

That is how many women still remember period underwear from the drugstore.

Thick absorbent pads and a pair of briefs that show clearly through clothing.

It is no wonder that the typical “diaper feeling” often arises.

my•mense has solved exactly this problem.

Thanks to the special honeycomb structure, liquid can be efficiently distributed and absorbed – without needing a thick, bulky absorbent pad.

As a result, the panty is only about 1–2 mm thicker than normal underwear. On top of that, there are seamless models that are barely visible even under tight clothing.

The result: High absorbency – without the typical diaper feeling.

4. ⁠"With period underwear, you're sitting in your own blood for hours"

Sounds logical at first.

After all, the blood ends up directly in the panty.

With other period underwear brands, the problem is often that liquid is not absorbed quickly enough and remains on the surface.

That is exactly what causes this wet, sticky feeling.

This is exactly the problem that my•mense solves with its innovative 4-layer SafeLayer™️ technology.

The top layer quickly absorbs liquid and channels it into the absorbent core using its special honeycomb structure.

There, it is securely locked away – away from the surface and therefore away from your skin.

The result: The surface stays significantly drier, instead of you feeling like you are sitting in your own blood for hours.

5. "Period underwear is way too expensive"

At first glance, it really does seem that way.

A period panty costs more upfront than a pack of tampons or pads.

And with other period underwear brands, a single pair usually costs over €40. It’s no wonder, then, that many people are initially put off by the price.

The math looks different with my•mense.

Especially with our bundles, you save significantly and can get a panty for an average of just €17.

And unlike tampons or pads, you don’t have to buy them every month.

With proper care, you can reuse your my•mense panty for up to 3 years.

This means: Invest once, wear it again and again – instead of buying new tampons and pads every single month.

And compared to many other period underwear brands, with my•mense you get strong absorbency and high comfort at a much more attractive price.

The truth: Period underwear doesn't have to be an expensive investment. With the right bundle, it can actually really pay off in the long run.
