A pore strip costs a few cents to make and is judged in about ten minutes. The consumer wets the nose, applies the strip, waits for it to stiffen, and removes it to see the result. That single visible outcome, whether it is satisfying or disappointing, decides whether the product is repurchased, and it is decided almost entirely by the adhesive system and the substrate rather than by any active ingredient.
This is a category where private label brands can build a strong, high-margin line extension with very little formulation complexity, provided the specification is written properly. It is also a category where a badly specified strip produces complaints about pain, redness, incomplete removal or adhesive residue, all of which are avoidable.
This guide covers the practical development of pore strips and nose packs for private label manufacturing: substrate and adhesive selection, the test programme that predicts field performance, claims that can be defended, and a brief template that avoids the usual rework cycles.
Why a small-format product carries an outsized complaint risk
Three factors drive the complaint rate. First, the application area is the nose, which is highly visible and sensitive, so any redness is immediately obvious. Second, removal is mechanical, so the peel force directly determines whether the experience reads as effective or as painful. Third, the consumer expectation is unusually specific: this category has been marketed for decades on a visible-result promise, and a strip that removes little reads as a failure even if the chemistry worked as designed.
The correct response is not to maximise adhesion. A strip that grips hard removes more, but also removes more corneocytes and produces more irritation, which drives returns and negative reviews. The engineering task is to hold the strip in place, remove material from the follicle openings, and release from the skin without a painful peel. Those three requirements pull against each other, and the balance point has to be found with testing rather than with a rule of thumb.
Substrate and adhesive formats in practice
Four formats cover the category, and they behave differently enough that a brand intending to sell two of them needs two development tracks.
| Format | Substrate | Adhesive approach | Consumer result | Main risk |
|---|---|---|---|---|
| Classic charcoal or starch pore strip | Non-woven or paper with a powdered filler | Water-activated tack from the filler system | Visibly removed material on the strip | Variable tack depending on filler uniformity |
| Hydrogel nose strip | Cast gel on support film | Contact adhesion from the gel surface | Hydrating, less aggressive removal | Edge lift and drying out |
| Wash-off nose pack or clay mask | Not applicable | Not applicable, film forms on drying | Softer, repeated-use routine | Consumer perceives less instant result |
| Peel-off nose film | Cast in place from a squeeze pack | Polymer film | Theatrical removal experience | Difficult removal around nostril creases |
The classic strip remains the highest-volume format and the one most associated with the category. Its performance depends heavily on how uniformly the filler powder is dispersed, because the water-activated tack varies locally with the powder loading, and uneven tack produces a strip that removes well in the middle and releases early at the edges.
How is a water-activated pore strip specified?
A water-activated strip is manufactured by coating a substrate with a formulation that is essentially a filler, a binder and water. The filler provides the bulk and the capillary structure after drying. The binder holds it together and controls how much force the strip can transmit before it delaminates.
Four specification points decide whether the finished strip performs. Coating weight determines how much material there is to grip, and both too little and too much are defects. Drying profile determines the pore structure and therefore the water uptake rate. Substrate strength has to exceed the peel force, or the strip tears on removal. And cut geometry has to fit a range of nose shapes without covering the eyes, which means the die line is a consumer-facing decision rather than a manufacturing detail.
Because the consumer activates the adhesive with water, the instruction on the artwork is part of the specification. A strip that is applied to a wet nose behaves differently from one applied to a damp nose, and the difference is large enough to change the result. The application instructions should be written from the stability and performance testing, not written first and tested afterwards.
The test programme that predicts field performance
Three tests do most of the work in this category, and they are cheap enough that there is no reason to skip them.
A peel force test measures the force required to remove the strip from a standardised substrate at a defined angle and speed. This is the single most predictive number, because it captures the balance between retention and pain. Panels in this category usually land on a narrow window, and a specification outside it will produce either lift-off complaints or removal complaints.
A residue test checks whether adhesive or filler remains on the skin after removal. Residue is the most common complaint that generates a return, because the consumer cannot clean it off easily and associates it with a poor-quality product.
A water uptake test measures how quickly and how completely the filler system activates. This is where batch-to-batch variation shows up first, so it belongs in the incoming raw material specification as well as in the finished product specification.
Where a brand intends to claim a specific result, such as a reduction in the visible appearance of pores or a measurable reduction in surface sebum, the measurement protocol has to be defined before the study runs, including the instrument, the site, the time of day and the conditions, because sebum and pore appearance vary substantially with temperature and time since washing.
Which claims can be defended, and which cannot
This category attracts some of the most aggressive claim language in skincare, and most of it is difficult to substantiate.
Claims about removing blackheads are particularly exposed, because the dark material visible on a removed strip is a mixture of sebum, corneocytes and oxidised material, and describing it as blackheads removed is a strong assertion. Descriptive alternatives that speak to the appearance of the nose are safer and still communicate the benefit.
Claims about reducing pore size are also difficult, because pore size is a structural property that cannot be permanently changed by a cosmetic. Wording framed around the appearance of pores, or around the removal of material that makes pores look more visible, is more defensible.
Water-activated strips have one additional consideration: because the mechanism is mechanical, any claim implying a chemical or biological action, such as drawing out toxins or balancing oil production, is unsupported and should be avoided.
The practical rule for this category is that the strongest, most durable claim is a simple, honest description of the visible appearance after use, supported by a use test with a defined protocol. Brands that keep the language plain and the test rigorous have far fewer problems with both regulators and reviewers.
Manufacturing and quality control points
Pore strip manufacture is a converting process, so quality control focuses on coating weight, moisture content, cut tolerance and seal integrity rather than on tank chemistry.
Coating weight is measured by weight per unit area and is the usual release specification, because it correlates directly with the peel force. Moisture content matters because the strips must remain dry enough to activate on use; a product that has taken up ambient moisture in the warehouse will feel tacky in the pack and perform inconsistently. Cut tolerance is a die-cutting specification, and it needs to be tight enough that the strip sits correctly on a range of nose sizes. Seal integrity applies to any format delivered in a sachet or a sealed sleeve, since moisture ingress is the main shelf-life risk.
For brands, the important implication is that the incoming inspection plan should test the raw substrate and the filler, not only the finished strip, because variation in either one changes the end result more than most brands expect.
Packaging and format considerations
Pore strips are usually sold as a multi-unit pack of individually sealed strips, or as a set of strips on a sheet in a sleeve. Both formats have trade-offs. Individually sealed strips protect each unit and support a premium price, but add converting cost and material. A sheet of strips in a sleeve is cheaper and lets the consumer take one without opening a sachet, but the whole sheet is exposed to the environment each time it is opened, which shortens the usable life after opening.
Where the brand wants a sustainability story, the sleeve format has a real advantage because it eliminates a sachet per use. If the outer packaging will carry a recyclability claim, confirm what the target market's guidance actually requires, since the claim carries its own evidence burden.
What should a pore strip brief contain?
Include the format, the number of units per pack, the nose size range the strip must fit, the peel force window if the brand has a preference, any visual differentiation such as a charcoal colouring, the claims the brand intends to publish, the target markets, the first order quantity and the target cost. If the brand has a competitor strip it wants to match, send a physical sample: peel force is not something that can be matched from a description, and a reference sample saves a whole sample round.
Compliance: EU, US and China
In the European Union a pore strip is a cosmetic under Regulation 1223/2009, requiring a Responsible Person, a Product Information File, a Cosmetic Product Safety Report and CPNP notification. Claims are assessed against the common criteria in Regulation 655/2013, and it is precisely this category where loose claims about blackheads and pore size are most likely to be challenged.
In the United States, the Modernization of Cosmetics Regulation Act applies, with facility registration, product listing, safety substantiation and adverse event obligations on the brand or importer. Mechanical removal products generate more adverse event reports than average, so a documented complaint handling process is worth putting in place before launch.
In China, cosmetics are managed under the Cosmetics Supervision and Administration Regulation. Because claims about acne or about removing blackheads can push a product toward the special cosmetics category, the claim set should be confirmed against the classification rules before the project timeline is set.
Frequently asked questions about pore strip OEM
What is the minimum order quantity for private label pore strips?
MOQ is driven by the coating run and the die-cut tooling, plus the sachet or sleeve converting minimum. It is higher than for a liquid-filled product and is quoted per project once the strip geometry is fixed.
Can you produce strips in custom shapes?
Yes, subject to die-cut tooling. Custom geometry is often used to fit a specific nose shape or to create a distinctive look, and it is a one-off tooling cost rather than a recurring one.
Can you match a pore strip we already sell?
We can benchmark an existing product and develop a specification to the same performance brief. We do not copy a third party formula, and we ask brands to confirm they hold the rights to any specification they ask us to reproduce.
How long does development take?
A first sample typically takes two to three weeks after the specification is frozen, with two rounds being common because peel force has to be tuned against a panel. Tooling lead time for a custom die is additional.
Do you supply the reports needed for filing?
Yes. Stability, pack compatibility, microbiological assessment where applicable and any use testing we arrange are documented for inclusion in the technical dossier.
