Are Reusable Period Panties Really Safe & Hygienic?

Let’s unpack these questions and discuss how to know if your period product is safe for you.

What Makes Period Panties Reusable?

A reusable period panty isn’t just regular underwear with extra padding stitched in. The best period panties are designed using a multi-layer gusset system that absorbs and locks in menstrual fluid. At Mahina, each pair is built with:

• A moisture-wicking top layer to keep you dry
• A super absorbent core that traps blood
• A leak-proof bottom layer to keep stains at bay
  
  

These layers are bonded directly into the underwear, meaning there are no shifting pads, no wings, and no need for inserts. Everything is built in - secure, comfortable, and designed to last through your cycle. Mahina’s period panties are tested to be washed for up to 100 washes, and made with OEKO-TEX certified fabrics, making them ideal for everyday use, overnights, or long days out.

What Makes A Period Product Safe?

If you're considering switching to a sustainable period product, here’s what to look for in terms of safety:

• Fragrance-free and dye-free materials
• Breathable fabrics like cotton or modal
• Skin compatibility and toxicology testing
• Compliance with international safety standards
• Transparency around checks and certifications
  
  

Mahina’s period panties check all these boxes.

Tested by NABL-accredited labs to make sure it's completely safe for your body — from fabric to thread, every skin-touching part is checked to meet the strictest EU and US safety standards. That means no toxic chemicals, no restricted substances, and no banned amines. In short, our product won’t just keep you dry, it’ll keep you safe.

But what happens after six months of use? We tested that too. Mahina’s absorbent underwear for women was tested in its used state. Yes, after real-world wear. The result? A total microbial count that’s well below 1000 cfu/gm, providing minimal bacterial, yeast, and mould growth. This microbiological testing ensures that even over time, Mahina remains hygienic and safe to wear.

That said, our reusable period panties do need a little care from your end. Hygiene depends not just on how they’re made, but also on how you use and wash them. Here are two simple rules:

1. Always rinse and wash properly: Use mild detergent, avoid fabric softeners, and air dry only.
2. Choose the right size: A snug, secure fit ensures that the absorbent gusset stays aligned and does its job. Especially when picking period panties for heavy flow, the right fit and size is imperative to ensure you’re stress-free and leak-free.

Poor wash care or wearing a loose-fitting pair can affect performance, but when you follow basic guidelines, they’re perfectly safe.

How Long Can You Wear It In One Go?

This is one of the biggest perks. Unlike tampons that need to be changed every 4 to 6 hours, a reusable period panty is built for longer wear. Mahina's Period Panty can be worn for up to 12 hours, helping you go about your day stress-free!

Although our product has been tested to be washed and reused for up to 100 washes, the key to making sure you reach there is also in your washcare techniques. Here are a few tips -

• Rinse your reusable period panty in lukewarm or cold water immediately after use
• Do not wring or twist the fabric; gently press out the blood and hold it under running water till it runs clear
• Use a mild, fragrance-free detergent and avoid bleach or fabric softeners
• Wash only with cold or lukewarm water to protect the fabric and effectively remove blood
• Let it air dry flat or clip it at the waistband instead of using a dryer

So, Are They Safe?

Yes. Mahina's Period Panties are made responsibly, and when cared for properly, they are a safe, hygienic, and more body-friendly alternative to traditional disposable products. They cut down on waste, reduce skin irritation, and offer you reliable protection without the discomfort of plastic-based products. They’re not just good for the planet, they’re better for your peace of mind. No leaks. No chemicals. No second-guessing!
