What’s Really in Your Pad? Why It’s Time to Rethink Your Period Care

Why More People Are Searching “What’s in My Period Products?”


If you've ever googled “Are pads toxic?” or “What’s the safest period product?”, you’re not alone.

A growing body of research has uncovered some unsettling truths: many mainstream pads and tampons contain harmful chemicals like PFAS (so-called “forever chemicals”), phthalates, parabens, VOCs, dioxins, and even lead.

These  chemicals have been linked to:

  • Hormone disruption
  • Cancer risks
  • Reproductive health issues
  • Endometriosis
  • Skin irritation and allergic reactions

And yet — you’ll rarely see them listed on the box.

Your Skin Absorbs More Than You Think

Here’s the kicker: the skin in the vulva and vaginal area is thinner and more absorbent than almost anywhere else on your body. Period products stay in contact with this area for extended periods — meaning prolonged exposure to chemicals, often without us knowing it.

One study even found arsenic and lead in 30 different tampons. Another found PFAS added to pads  to keep them “leak-proof.” These are materials you wouldn’t accept in your food or skincare. So why should they be in your period care?

Your Health Deserves Better — and So Does the Planet

More people are ditching conventional pads and tampons for sustainable period products that are better for their bodies and the environment.

Why Inoya Exists

Inoya was born from frustration — the kind that builds when you discover that most mainstream period products still contain hidden chemicals, haven’t changed in decades, and offer little to no ingredient transparency. As a woman, a mother, and a public health professional, I knew we could do better.

Our periods deserve more than outdated designs and questionable materials.

That’s why I created Inoya: a brand committed to non-toxic, sustainable period products that are safe, soft, and thoughtfully made. From our reusable pads to our medical-grade menstrual cup, every product is designed with care, backed by testing, and driven by purpose.

Today, innovation and collaboration are at the heart of what we do — pushing for better standards, better materials, and a better experience for every person who bleeds.
