Are Sanitary Pads "Over-Engineered"? A Founder on Why More Absorbency Isn't Always Better

In a recent industry conversation I heard a point worth sitting with: China's basic hygiene performance may already be too good. It doesn't sound like praise, does it? Better quality should mean more peace of mind. A sanitary pad with more absorbency, a period pant with stronger protection — surely that's more worth buying? But when you put the question back into real life, "made stronger" and "what she actually needs" turn out not to be the same thing.

Does bigger absorbency actually reassure anyone?

Most people pick pads or period pants by absorbency, thickness, length, and the list of features. A bigger number gives a sense of safety: it holds more, so it should be less likely to fail. That instinct is completely fair. During a period, leak protection is the most basic thing that matters — overnight, on a commute, sitting for hours, or when changing isn't convenient, "will it hold?" is the first question.

From a development standpoint, absorbency and leak protection are baseline. You have to get them right. But once that baseline is met, does stacking more parameters and more functions make the product better? Not necessarily. A product faces different people, different cycle stages, different scenarios. Daytime commute and overnight sleep ask for different things. A heavy day and the tail end of a period ask for different things. Some women care most about leaks, some about breathability, and some can't stand waistband pressure or the feeling that they're wearing something at all.

When you stop distinguishing those scenarios and just chase more absorbency, more structure, more features, you end up charging her for performance she doesn't need — while the thing she actually cares about stays unsolved.

"Over-engineered" doesn't mean quality doesn't matter

Let me be clear: I am not saying hygiene products don't need high quality, or that better materials, tighter testing, and stable production don't matter. These are on-body products. Safety, material choice, production environment, and quality control all have to be taken seriously. Meeting the standards is the floor; managing the process is the responsibility; improving the experience is the long-term capability.

What I mean by "surplus" is narrower: the features and the cost have gone past what the consumer actually needs in a given scenario. A period pant's value isn't only how much it absorbs. It's whether it stays put all night, whether it disturbs her sleep, whether the waistband is comfortable, whether it's easy to get on and off, and whether she'll keep using it. A pad shouldn't be defined by a single number either. It has to balance absorbency, leak protection, softness, breathability, and how it feels to wear. Features aren't "more is better." They're "right thing, right scenario."

From stacking features back to "just right"

For years, competition in this category ran on parameters and features. One brand adds a design, another adds a material; one pushes a bigger absorbency number, another pushes a longer feature list. It does move the industry forward — but it can also make products more complicated and make it harder for her to choose.

I keep coming back to one simple logic: do the things she actually needs well, instead of doing everything you possibly can. That means product development can't stay in the lab and on the line. It has to go back into real life. When does she use it? How long does she wear it? Does she feel uneasy turning over at night? Does it feel stuffy in summer? Is it easy to change? How does her body feel after hours of wear? A lot of those questions can't be written as a spec number — but they decide whether she accepts the product or not.

Chinese consumers need products that fit them

The more I talk to people in the industry, the clearer it gets that we still need to understand Chinese consumers more deeply. Women in different regions, at different ages, with different lifestyles don't want the same thing. Pads, period pants, and diapers are all sensitive to body type, wearing habits, and use scenario. Design can't just copy what works in another market.

Building a consumer database that's closer to Chinese users, collecting real feedback, studying what different scenarios actually require — none of that is as visible as a new feature on a spec sheet. But it's exactly what decides whether a product is truly comfortable, truly fitted, and truly stable in her hands.

Why we do product, brand, and supply chain at once

I founded Hunan Nafei Biotechnology Co., Ltd. to make period pants, sanitary pads, and disposable underwear, focused on women's health. At the same time we run three house brands — Lancool, Na Xiaorou, and Na Xiaoshuang — and provide OEM and ODM from our Guangdong production base. To me these aren't separate businesses.

Supply chain work lets us see what different brands actually need and the pressure they're under on R&D, sampling, cost, delivery, and market shifts. Our own brands force us to face the consumer directly and take her judgment on positioning, experience, and long-term value. Only by facing both do you learn this: a product can't just look qualified in the factory or advanced on a page. It has to land in her life. She keeps using it, buys it again, and recommends it — that's the only proof it created real value.

A good product isn't the one with the biggest number. It's the one that solves the problem she actually has.

A good product isn't "more expensive" or "more complex"

The category will keep evolving. New materials, new structures, new ways to use them. Period pants are already changing habits for a lot of women. But one test won't change: does it solve her problem? If a product makes her more assured when she needs it, more comfortable over long wear, easier to understand when she buys, and closer to real value on price — then it's a meaningful upgrade. If it just adds parameters and cost without improving the thing she cares about, it's worth rethinking.

So, is China's hygiene industry already "over-qualified"? My answer: on certain basic performance and function metrics, yes — the industry needs to shift from "more is better" to "just right." But on truly understanding the consumer, improving comfort, and building product standards that fit Chinese women, we still have a long way to go.

What I want Nafei to do, more than just produce, is to think clearly about why each product exists and whose problem it's solving. Because what women actually need was never a bigger number. It's something she trusts, reaches for again, and feels good wearing in real life. If you're building a brand in this space and want a manufacturer that thinks the same way — start with our OEM vs ODM guide or talk to us.

Does a higher absorbency number always mean a better pad?

Not always. Absorbency is a baseline you have to get right, but beyond a point, a bigger number adds cost without fixing what she actually cares about — fit, comfort, breathability, and how it feels over hours.

What does "over-engineered" mean for a period product?

It means the features and cost have gone past what the consumer needs in her real scenario. A product that's "just right" fits the moment — heavy day vs light day, daytime vs overnight — instead of piling on every capability.

How should a brand balance absorbency against comfort?

Start from the use case, not the spec. Decide what matters most in each scenario — leak protection overnight, breathability in summer, a soft waistband for long wear — then optimize for that, rather than competing on a single absorbency number.

Why does understanding the local consumer matter for OEM?

Fit, body type, wearing habits, and climate all change what "comfortable" means. A feminine hygiene manufacturer that builds products around a real consumer database makes SKUs that actually fit the market — not ones copied from another region.
