What's Really Touching Your Skin — And Why It Matters, Especially for Teens
There's a question we don't ask nearly enough: what is actually in the products we put against our bodies every single month?
For most of us, the answer is a mystery. Period products aren't required to list their full ingredients the way food or skincare is. So we trust the packaging, the marketing, the brand name — and we move on. But your body deserves more than trust by default. It deserves transparency.
That's the conversation we want to open up today — what's really in period products, why it matters more than people realize, and why it matters even more for teens experiencing their first periods.
It's Not the Fabric. It's What's Done to the Fabric.
Here's something we say often at Lunam: the polyester is not the problem — the chemicals are.
Synthetic fibers aren't inherently unsafe. The concern is what gets added to fabric during manufacturing — waterproofing agents, dyes, finishes — many of which are added without much oversight or disclosure. Some of these treatments have been linked to skin irritation and long-term chemical exposure with regular, close contact use, which is exactly the kind of contact period products involve, day after day, cycle after cycle.
A 2025 University of Notre Dame study found PFAS — so-called "forever chemicals" — in a significant share of period underwear tested, including some brands that carried certifications. Certification is a meaningful starting point. It isn't the finish line.
Why This Conversation Matters Even More for Teens
A first period is a milestone. It's also, often, the first time a young person is making decisions about what touches one of the most sensitive parts of her body — usually without much guidance on what to actually look for.
Teen skin can be more reactive, and habits formed early tend to stick. If the first period products a girl ever uses are treated with unknown chemicals, that becomes her unquestioned baseline for years. Starting with something safer isn't just about this cycle — it's about setting a standard she'll carry forward.
This is part of why Lunam offers sizing designed to fit younger, first-period bodies. Non-toxic shouldn't be something you graduate into once you're older and more informed. It should be where everyone starts.
What "Non-Toxic" Actually Means at Lunam
We don't think safety should be a marketing word. It should be a testing result.
Lunam is OEKO-TEX Standard 100 certified — an internationally recognized standard that screens for a wide range of harmful substances in textiles. But we didn't stop there. Every Lunam product also goes through independent chemical testing at a lab in Miami, above and beyond what the certification requires.
The only period underwear tested twice — because once wasn't enough.
That's not a tagline. It's how we build a product we'd hand to our own daughters, sisters, and younger selves without a second thought.
A Softer Way to Experience Your Cycle
Choosing what goes near your body shouldn't require a chemistry degree. It should just require a brand willing to show its work.
That's what we're building at Lunam — period underwear that's leakproof, comfortable, and genuinely tested, for every body that needs it, at every age it starts.
A softer way to experience your cycle — without toxins, without compromise.
