Acne is one of the highest-volume search terms in skincare and one of the most dangerous words a cosmetic brand can put on a label. In the European Union and most of Asia, acne is a medical condition, and a product claiming to treat it is not a cosmetic. In the United States, certain anti-acne ingredients and claims fall under a specific over-the-counter drug framework rather than the cosmetic framework.
The commercial tension is unavoidable. Consumers with blemish-prone skin search using the word, and a product that avoids the word entirely can be difficult to find. But the brand that uses it as a treatment claim inherits a regulatory pathway that is far more expensive than the product justifies.
There is a workable route through, and it runs through the claim rather than the formula. This guide covers the boundary in each major market, the actives that can be used within the cosmetic framework, the formulation approach for oily and blemish-prone skin, and the testing that supports the claims that are available.
The drug and cosmetic boundary in this category is actively enforced and the position differs by market. Confirm the classification of your specific claim set with a regulatory adviser before the artwork is printed.
Why acne is the riskiest word in skincare
The risk is not in the ingredient. It is in the assertion. A cleanser containing salicylic acid is a cosmetic. The same cleanser claiming to treat acne is, in most markets, making a therapeutic claim that a cosmetic is not permitted to make.
Three consequences follow from getting this wrong. The product may be classified as a drug or a medicinal product, which brings pre-market approval, testing and labelling requirements that are disproportionate for a skincare item. It may be seized or delisted. And the retailer or distributor carrying it may face enforcement, which damages the commercial relationship more than the product loss.
The practical position for a cosmetic brand is that the product can be described by what it does to the skin's appearance and by how it is formulated. It can be positioned for oily skin, for the appearance of blemishes, for congested-looking skin and for a clearer-looking complexion. It cannot claim to treat, cure, prevent or reduce a medical condition.
Where the boundary sits in each major market
In the European Union, acne is a disease, and any claim to treat it takes the product out of the cosmetic definition. A cosmetic may make claims about the appearance of the skin, and claims must satisfy the common criteria in Regulation 655/2013. The practical consequence is that anti-acne positioning is generally unavailable, and products in this space are positioned on oil control, cleansing and the appearance of blemishes.
In the United States, the framework is different and, in one respect, more permissive. Certain anti-acne ingredients have a monograph that permits an over-the-counter drug claim if the product complies with the monograph requirements, including the permitted active, its concentration, the permitted claim wording and the labelling. A brand can therefore sell an anti-acne product in the US, but it is a drug rather than a cosmetic and it must meet the drug requirements. A brand that does not want that obligation makes no anti-acne claim and stays in the cosmetic framework under the Modernization of Cosmetics Regulation Act.
In China, cosmetics are managed under the Cosmetics Supervision and Administration Regulation, and efficacy claims are subject to the cosmetic efficacy claim requirements, which means the claim has to be substantiated before it is published. Claims relating to acne require particular care, and the permitted claim scope is narrower than the marketing language commonly used in the region. Confirming the acceptable claim wording with a local regulatory agent is a routine and worthwhile step.
The pattern across markets is consistent: the ingredient is usually permitted, the claim is the constraint, and the claim wording that is acceptable differs from market to market. A single claim set for a global launch is rarely achievable in this category.
Actives that work within the cosmetic framework
Several actives are well established in oily and blemish-prone skin products and can be used within cosmetic positioning.
Salicylic acid is the most widely used. It is oil-soluble, it penetrates the follicle, and it is available as a permitted cosmetic ingredient for certain product types and concentrations, with the permitted level depending on the function and the product type. It appears in cleansers, toners and treatment products. Because the regulatory treatment depends on both function and concentration, the intended use level and the declared function have to be decided before the formula is fixed rather than after.
Niacinamide is the second workhorse. It is well tolerated, it supports barrier-related positioning and it is associated with a reduction in the appearance of oiliness and of uneven tone. It works across a wide pH range and is easy to formulate, which makes it the natural partner for a salicylic acid product in a two-step routine.
Zinc salts are frequently included for oil control positioning, and several botanical actives including green tea, sophora and centella appear in the category for soothing support. Sulfur appears in some products but its use level and permitted application are constrained in some markets, and its odour requires managing in the brief.
Two ingredient families sit firmly outside the cosmetic framework and should be recognised as such. Benzoyl peroxide and the topical retinoid used in acne treatment are drug actives in the markets where they are permitted at all, and a brand planning a product around them is planning a drug project, not a cosmetic one.
| Active | Role within the cosmetic framework | Boundary note |
|---|---|---|
| Salicylic acid | Exfoliating and pore focused positioning | The permitted concentration depends on the declared function and the product type, and differs by market |
| Niacinamide | Even tone, barrier support and the appearance of oiliness | Widely permitted and straightforward to file across markets |
| Zinc salts | Oil control positioning | Widely permitted; confirm the specific salt and the use level |
| Botanical soothing actives | Comfort and perceived calming | Check standardisation, allergen potential and colour contribution |
| Sulfur | Appears in some products | The use level and permitted application are constrained in some markets, and the odour has to be managed |
| Benzoyl peroxide | Not a cosmetic active | Falls under the drug framework in the markets where it is permitted |
| Topical retinoid used in acne treatment | Not a cosmetic active | Falls under the drug framework; a different project entirely |
Formulating for oily and blemish-prone skin
The formulation logic in this category is a balancing act, because the instinct to strip oil is exactly the wrong approach for most consumers. Aggressive cleansing and high alcohol content produce a temporary dry feeling and a longer-term increase in oiliness and reactivity, and they are the most common reason a blemish-prone consumer abandons a routine.
The approach that works in practice has four characteristics. The surfactant system is mild, non-ionic or amphoteric, and dosed at a level that cleanses without stripping. The oil phase is light and non-congesting, using esters and squalane rather than heavy butters, and the formula is designed so that a consumer with combination skin can use it daily. The humectant load is adequate so that the skin does not compensate for dehydration with additional oil. And the pH is skin-compatible rather than strongly acidic, unless the product is a specific exfoliating treatment where a lower pH is functional.
Texture matters commercially in this category. A product that feels heavy will not be used by the target consumer, regardless of its technical merit, so the sensorial brief deserves the same attention as the active content.
The role of the exfoliating step
Chemical exfoliation is central to the category, and it is also where brands most often create a problem. Beta hydroxy acid exfoliation is effective but it is a treatment rather than a daily routine step for many consumers, and a product that encourages daily use of a strong acid can produce the reactivity that the barrier category then has to fix.
The formulation decision that helps most is to build the exfoliating product so that it works at a lower frequency, either through a lower acid concentration, a buffered system or a delivery format such as a rinse-off or a pad that limits contact time. The product can then be positioned as a weekly or twice-weekly step, which is both better for the consumer and easier to defend in the claim set.
Testing that supports available claims
The claims available in the cosmetic framework are appearance and perception claims, and they are testable.
Sebum measurement supports oil control claims and is a straightforward instrumental study. Image analysis and trained visual grading support claims about the appearance of pores and the appearance of blemishes. Corneometry supports hydration claims and matters because the target consumer is often dehydrated from over-cleansing. And a patch test or repeat insult patch test supports tolerance claims, which are commercially valuable in a category where consumers have often reacted badly to previous products.
Where a brand wants a consumer-perception claim, such as participants reporting that their skin looks clearer, the study design defines the value of the result. The important details are the panel, the duration, the assessment instrument and the question wording, all of which should be agreed before the study rather than after the data is in hand.
Packaging and format considerations
The category favours formats that support a routine rather than a single hero product: a cleanser, a toner or essence, a treatment product and a light moisturiser. Packaging should support controlled dosing, because over-application of an acid product is both a waste and an irritation risk. Airless pumps and narrow-orifice bottles work well for treatment products.
Where a brand wants a pad or a single-dose format for the exfoliating step, the pack becomes a converting project rather than a filling project, with its own minimum order quantity. That is worth knowing before the range is finalised, because it can change the launch sequence.
What should a brief contain?
Specify the product format and its place in the routine, the target skin type and the level of oiliness, the actives and their intended concentrations, whether the brand intends to make any claim touching the blemish area and the exact wording proposed, the tolerance requirement, the pack type, the target markets, the first order quantity and the target cost. If the brand intends to sell in the United States, state explicitly whether the product will make an anti-acne claim, because that single decision determines whether the project is a cosmetic or a drug.
Frequently asked questions about blemish-prone skin product OEM
Can I sell an anti-acne cosmetic?
In the United States, an anti-acne claim generally brings the product within the over-the-counter drug framework, which requires compliance with the monograph. In the European Union and most of Asia, acne treatment claims are not available to a cosmetic. The ingredient is usually permitted; the claim is the constraint.
What concentration of salicylic acid can I use?
The permitted level depends on the market, the product type and the declared function of the ingredient. We confirm the position per market before the formula is frozen.
Can you match a cleanser or toner we already sell?
We can benchmark an existing product and develop a formula to the same brief. We do not copy a third party formula, and we ask brands to confirm they hold the rights to any formula they ask us to reproduce.
How long does development take?
A first sample typically takes two to three weeks after the brief is frozen, with two or three rounds common. Instrumental sebum and hydration studies run in parallel with stability work.
Do you supply the reports needed for filing and claims?
Yes. Stability, pack compatibility, microbiological challenge and safety documentation are standard, and we can arrange sebum measurement, image analysis and patch testing through accredited laboratories.
