We asked 1,181 women what their biggest concerns are regarding period underwear

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

Updated: September 1, 2026 

"5 reasons why buying period underwear should be well-considered"

The idea actually sounds perfect:

 

You put on a pair of underwear in the morning, it absorbs your period, and you don't have to worry about a thing for several hours.

 

✅ No tampons.

✅ No slipping pads.

✅ No constant changing.

✅ No monthly waste.

 

And yet, many women hesitate before their first purchase.

 

That’s why we asked 1,181 women directly:

“What is your biggest concern when buying period underwear?”

 

The answers were surprisingly clear:

  • Around 47% are concerned about leaking and a lack of reliability.
  • Around 26% about fit and comfort.
  • Around 15% about hygiene, odor, and cleaning.
  • Around 7% about quality, durability, and value for money.
  • Around 5% about skin compatibility and potential harmful substances.

*Multiple answers were possible.

 

So, women don’t just want any absorbent underwear.

 

They want period underwear they can truly trust, even on a heavy day, during a long workday, and at night in bed.

 

And that is exactly the difference between just any period underwear – and my•mense.

Concern #1: "What if it leaks after all?"

That was by far the most common concern.

And quite honestly?

It is absolutely understandable.

 

Because hardly anything is more uncomfortable than inconspicuously checking the chair after standing up.

 

Turning around in the mirror to check if anything is visible.

 

Or waking up at night and immediately reaching for the bed sheet.

 

That is why the SafeLayer™️ technology from my•mense was not just designed to somehow absorb liquid.

 

It is intended to absorb it quickly, store it securely, and prevent it from leaking outwards or out the sides.

 

Multiple layers work together to achieve this:

 

1️⃣: The SafeDry™️ layer absorbs the liquid and wicks it away from the surface.

2️⃣&3️⃣: Two SafeCore™️ layers securely store the liquid inside.

4️⃣: The SafeProtective™️ layer protects your clothing on the outside.

 

And the additional SafeSide™️ barrier is designed to prevent liquid from leaking out the sides.

 

Depending on the model, a my•mense panty can absorb an amount of liquid equivalent to up to five tampons—and, depending on your flow, protect you for up to twelve hours.

 

For heavy days and nights, there are particularly absorbent models like Oleander or Dahlia.

 

Dahlia features a long protective layer from the front waistband to the back. This means you are protected even when you sleep on your stomach, back, or side.

 

So you don't have to hope that your period underwear stays leak-proof. It was developed exactly for this moment.

Concern no. 2: "What if it feels damp or like a diaper?"

Many women imagine period underwear to be like a thick pad sewn firmly into a pair of panties.

 

So:

 

❌ Thick.

❌ Stiff.

❌ Damp.

 

And uncomfortable between the legs.

But that is exactly what should not happen with my•mense.

 

The SafeDry™️ layer wicks liquid away from the surface into the absorbent core underneath.

 

It is stored there instead of simply remaining on the skin.

 

Despite its high absorbency, the protective layer is only about a millimeter thicker than regular underwear.

✅ No typical diaper feeling.

✅ No rustling.

✅ No wings that slip.

✅ No thick pad that makes itself felt with every step.

 

In addition, there are different cuts for different needs:

 

Seamless styles that are barely visible under tight clothing.

 

Styles with a higher waistband for more support.

And boxer shorts with an extended protective area for the night.

 

The truly brilliant thing about good period underwear is that, after a while, you can forget you are wearing a period product at all.

Concern no. 3: "Is this really hygienic – and won't it start to smell?"

This concern also came up again and again:

 

“Don’t you end up sitting in your own blood for hours?”

“Do the panties actually get clean?”

“What if others can smell something?”

 

The answer is simple:

Period underwear is hygienic as long as the fluid is quickly wicked away from the surface and the panties are properly cleaned afterwards.

 

With my•mense, the fluid is directed into the absorbent core and stored there.

 

After wearing them, rinse the panties with cold water, wash them in the washing machine at 40-60 degrees, and then let them air dry.

 

That is all you need to do.

 

The only important thing is not to use fabric softener or bleach, as these can impair the absorbent fibers.

 

And, of course, as with any period product:

 

Change your panties depending on your flow—at the latest when they feel damp or after a maximum of twelve hours.

 

When worn and cared for correctly, period underwear is no less hygienic than other washable underwear. It is simply much more functional.

Concern No. 4: "What if I spend a lot of money and the panties break after a short time?"

A period panty costs more than a single tampon.

 

But a tampon ends up in the trash after a few hours.

 

You can wear high-quality period panties again and again.

 

With proper care, your my•mense period underwear will last you about two to three years.

This not only saves you from having to buy new tampons and pads every month.

 

You also no longer have to constantly worry about having enough period products at home in time.

 

And that is exactly why you shouldn't choose period underwear based on the lowest price.

 

Because the cheapest panty ends up being expensive if it leaks, fits uncomfortably, or loses its absorbency after just a few washes.

 

Good period underwear is not a disposable product. It is an investment in many more relaxed periods.

Concern no. 5: "What kind of materials am I actually wearing in my intimate area?"

The vulva is one of the most sensitive areas of the body.

 

That is why many women wanted to know whether period underwear contains biocides, PFAS, or other substances of concern.
 

At my•mense, we consciously avoid biocides and PFAS.

 

The SafeLayer™️ technology was developed by medical professionals - with the goal of combining high absorbency with the most comfortable skin compatibility possible.

 

Because period underwear should not just be leak-proof.

It should also still feel comfortable on the skin even after several hours.

 

✅ Without unnecessary antibacterial finishes.

✅ Without permanent silver treatment.

✅ And without substances that you wouldn't want to wear directly against your intimate area for many hours every month.
