Why 15p Per Cleanse Makes the INKEY Oat Cleansing Balm the Smartest Skincare Buy

15p. That’s roughly what one cleanse with the INKEY Oat Cleansing Balm costs, once you break the price down to what actually happens each time you use it. It’s a small number, but it answers a question a lot of people quietly ask themselves while stood in front of a bathroom shelf full of skincare: does “better” have to mean “more expensive”?

At The INKEY List, we don’t think it does, and we think the gap between perceived value and actual value in skincare is one of the biggest sources of confusion for shoppers. A lot of the industry runs on the assumption that a higher price tag signals a better formula. We built our entire brand on cutting through that assumption with clear guidance and proven ingredients, so here we’re putting our own product under the same scrutiny we’d want applied to anyone else’s claims.

The product under the microscope is the Oat Cleansing Balm - £15 for 150ml, designed to melt away makeup and SPF in around 30 seconds without stripping the skin afterwards. It’s one of those products that looks simple on the shelf but does a lot of quiet, well-engineered work once it’s on your fingertips.

This blog is going to do three things. First, we’ll walk through the actual cost-per-use maths behind the 15p figure, step by step, so you can see exactly how we got there rather than just taking our word for it. Second, we’ll open up the formula itself and explain what’s inside the tube and why those ingredients were chosen for a balm cleanser specifically. Third, we’ll look at how it performs across different skin types, how it fits into a wider double cleanse routine, and how it stacks up against the broader UK cleansing balm and makeup remover balm market - all without resorting to vague, feel-good language that doesn’t actually tell you anything useful.

The first step is breaking down exactly how that 15p figure is calculated, because a value claim is only as good as the working behind it.

The Real Maths: How We Got to 15p a Cleanse

Let’s start with the two numbers that matter: £15.00 and 150ml. That’s the UK retail price and size of the Oat Cleansing Balm as it currently stands, and it’s the foundation for everything else in this section. No promotional pricing, no “was £20, now £15” inflation to make the number look better than it is - just the standard shelf price, divided honestly.

The next part of the equation is usage. Balm cleansers are concentrated by design, which means you don’t need very much product to get the job done. A typical application sits somewhere between a pea-sized amount and a 20p-coin-sized amount, which translates to roughly 1.5g per cleanse. That might sound like an oddly specific figure, but it’s the kind of detail that actually matters if you want an honest answer rather than a rounded-up marketing one.

So here’s the working, laid out plainly:

1. A 150ml tube of the Oat Cleansing Balm contains approximately 150g of product (balm formulas are close enough to a 1:1 ml-to-gram ratio that this is a fair working assumption).
2. At roughly 1.5g per cleanse, that 150g tube delivers approximately 100 individual cleanses.
3. £15.00 divided by 100 uses comes out to exactly 15p per cleanse.

That’s it. No hidden assumptions, no best-case scenario cherry-picking - just a straightforward division sum that anyone can replicate with the same tube in their bathroom cabinet.

To put that in perspective, 15p is less than the price of a single pack of chewing gum in most UK supermarkets, and it’s a fraction of what people routinely spend on a coffee, a bus fare, or a bag of crisps without a second thought. We’re not making that comparison to be cute about it - we’re making it because people are generally quite good at judging small, everyday costs, and quite bad at judging the real cost of a skincare product sold as one lump sum. Fifteen pence is a number your brain can actually hold onto, in a way that “£15.00 for 150ml” simply isn’t.

This is also where the brand’s wider philosophy comes into play. Our approach has always been built around “Clear guidance. Proven ingredients. Real results.” - and cost transparency is a natural extension of that. If we’re asking you to trust the science behind a formula, it only makes sense to apply the same rigour to the price you’re paying for it. A product can’t claim to be accessible if the real-world cost-per-use is quietly much higher than the headline price suggests.

There’s one more detail worth flagging, because it has a direct and measurable effect on that 15p figure: packaging format. The Oat Cleansing Balm comes in a tube, not a tub or pot, and that decision wasn’t cosmetic. Tube dispensing means you control the amount you’re using far more precisely than you can with a scoop-and-smear pot format, where it’s easy to take more than you need out of habit. It also means you can get right to the last bit of product at the end of the tube, rather than losing a meaningful amount stuck to the sides and bottom of a jar that a finger or spatula simply can’t reach. Our breakdown of why cleansing balms should come in a tube rather than a pot goes into this in more detail, but the short version is that format isn’t just a hygiene decision - it’s a cost-per-use decision too, and it’s one of the quieter reasons the real-world value of this balm holds up so well against the maths on paper.

Of course, none of this matters if the formula itself doesn’t perform. A low cost-per-use is meaningless if the product does a poor job on your skin - so now that the price has earned its stripes, it’s worth opening up the tube and looking at exactly what’s inside, and why those ingredients were chosen for this specific job.

What’s Actually Inside the Tube

A cleansing balm lives or dies on its formula, so let’s get specific. The Oat Cleansing Balm is built around two hero ingredients, and understanding what each one does - and why they’re paired together - explains why this product performs the way it does, rather than just being a nice-smelling thing you rub on your face before bed.

The first is 1% colloidal oatmeal. This is a finely milled oat ingredient long recognised for its calming, skin-soothing properties, and in this formula it’s included specifically to visibly reduce redness and ease dryness in sensitive or reactive skin. It’s a particularly useful inclusion in a cleanser, because cleansing is one of the most frequent points of irritation in a skincare routine - you’re doing it at least once, often twice, every single day, so a soothing ingredient here has an outsized impact on how comfortable your skin feels overall.

The second is 3% oat kernel oil. This is where the “balm” part of cleansing balm comes from - oat kernel oil is an emollient-rich oil that helps dissolve and lift away impurities, while also supporting the skin’s natural moisture barrier rather than working against it. This matters for anyone who’s ever come out of a cleanse feeling tight, dry, or squeaky-clean in the wrong way. That tightness isn’t a sign of a deep clean; it’s usually a sign the cleanser has stripped away more of your skin’s natural oils and barrier lipids than it should have, which can contribute to a damaged skin barrierover time.

Together, these two ingredients explain why the balm format works so well for removing makeup and SPF specifically. The principle at play is a simple one: like dissolves like. Makeup and sunscreen formulas are predominantly oil-based, which means a water-based cleanser alone often struggles to fully break them down - think of trying to rinse an oily pan with just water. An oil-rich balm, by contrast, binds to those oil-based products on contact, lifting them away efficiently. That’s why the Oat Cleansing Balm is designed to melt away makeup and SPF in around 30 seconds of massaging into dry skin, while the oatmeal content ensures you’re not left feeling stripped or uncomfortable once you rinse it off.

The best cleansers do their job without leaving skin feeling tight or reactive afterwards - that balance between effective and gentle is where a lot of formulas fall short.

This combination is also why the balm is positioned as the ideal first step in a double cleanse routine, rather than a cleanser you’d necessarily rely on alone if you’re dealing with specific concerns like excess oil or congestion. Its job is to remove the day - makeup, SPF, sweat, pollution - gently and thoroughly, setting the skin up for a second, more targeted cleanse to follow.

What makes this formula genuinely versatile is that it’s gentle enough to suit sensitive skin, dry or compromised skin, and general all-skin-type use, without being formulated in a way that only works for one category of skin. That’s a meaningful distinction in the makeup remover balm and cleansing balm space, where a lot of products either lean so richly emollient that they feel heavy on oilier skin, or are stripped back to the point that they don’t actually offer much comfort to reactive or dry complexions. The Oat Cleansing Balm is built to sit in a more universally workable middle ground, which is part of why it’s frequently searched for as a contender for best cleansing balm across a range of different skin concerns.

That universality is worth examining more closely, because “suitable for all skin types” is a claim that gets thrown around loosely in skincare marketing. It’s worth actually testing that claim against the specific, practical questions people have before they buy - which is exactly where we’re headed next.

Does It Work for Oily, Sensitive and Dry Skin?

There’s a persistent myth in skincare that oil-based cleansing balms are only for people with dry skin, and that anyone with oily or combination skin should steer well clear. It’s an understandable assumption - “oil on oily skin” sounds counterintuitive on the surface - but it doesn’t hold up once you understand how a well-formulated balm cleanser actually behaves. The key is that oil-based cleansers are designed to emulsify and rinse away completely with water, rather than sitting on the skin the way a facial oil might. Done properly, a balm cleanser shouldn’t leave any skin type, including oilier or combination skin, feeling greasy or residue-coated once rinsed.

For oily or blemish-prone skin, the Oat Cleansing Balm works best as the opening move in a double cleanse rather than the whole routine. Its job in this context is to dissolve makeup, SPF and the day’s surface build-up thoroughly and gently, without over-stripping the skin in a way that can actually trigger more oil production as skin tries to compensate. From there, a second, more targeted cleanse - such as INKEY’s Salicylic Acid Cleanser - can step in to address excess oil and congestion directly. If you want to understand why that pairing works so well together, our piece on salicylic acid and niacinamide as a duo for oily, acne-prone skin breaks down the science behind that second step in more depth.

For sensitive skin, this is arguably where the formula shines brightest. The 1% colloidal oatmeal content is specifically included for its soothing, redness-reducing effect, which makes the balm one of the gentler options available for reactive or easily irritated complexions. If your skin tends to flush, sting, or react to new products, a cleanser that calms rather than challenges the skin barrier during the very first step of your routine sets a much better tone for everything that follows.

For dry skin, the formula earns its keep twice over. Used as a standard cleanse, the oat kernel oil content means it won’t strip away the moisture your skin needs, which is one of the most common complaints people with dry skin have about foaming or gel cleansers. But it also has a secondary use worth knowing about: left on the skin for around 10 minutes before rinsing, it can double as a nourishing mask, giving drier skin types an easy way to get extra hydration out of a product they likely already own.

One point we always come back to, regardless of skin type, is the importance of a patch test before introducing any new product into your routine - and this is particularly relevant for anyone with reactive or sensitive skin history. Our guide on why you need to do a patch test walks through the simple method step by step. It’s not about creating unnecessary caution; it’s about setting realistic expectations and giving your skin a fair, low-risk introduction to something new, rather than applying it across your whole face on day one and hoping for the best.

So the short answer to “does it work for oily, sensitive and dry skin?” is yes - but with the caveat that oily and blemish-prone skin will get the most out of it when it’s paired with a complementary second cleanse, rather than used in isolation. That naturally raises the next question: what does that full routine actually look like, and where exactly does the balm sit within it?

Building the Perfect Double Cleanse (And Where the Balm Fits)

Double cleansing has gone from niche skincare-community jargon to a widely recommended standard practice, and for good reason - it’s a method, not a trend, and it’s backed by a simple logic that holds up under scrutiny. The idea is straightforward: an oil-based first cleanse dissolves makeup, SPF and surface-level impurities that water-based products alone struggle to break down, and a water-based second cleanse then goes in to address whatever specific skin concern you’re managing, whether that’s oil control, hydration, or barrier support.

The Oat Cleansing Balm is designed to be that first step, for essentially any skin type. Because its formula is built around gentleness and non-stripping removal rather than targeting a single concern, it works as a universal starting point regardless of whether your second cleanser is treating oiliness, dryness, or sensitivity. This is one of the more practical benefits of the balm’s formulation - you don’t need a different first-cleanse product depending on your skin type, which simplifies the whole routine considerably.

For the second step, the right pairing depends on what your skin needs most:

• Oily, congested or blemish-prone skin pairs well with the Salicylic Acid Cleanser (£14, 150ml), which targets excess oil and congestion directly after the balm has already cleared away the surface layer of makeup and SPF.
• Drier, more sensitive or dehydrated skin benefits from following up with the Milk Cleanser (£15, 180ml), which offers a gentler, more comforting second step for skin that needs extra moisture rather than oil control.

If you want the full method laid out from start to finish, our complete guide to double cleansing is the most thorough resource we have on the topic, covering order of application, timing, and how to adapt the method depending on your evening routine.

It’s worth returning to the cost-per-use logic here too, because this is where it becomes genuinely compelling rather than just a nice statistic about one product. If the Oat Cleansing Balm works out to roughly 15p per use, and a second cleanser like the Salicylic Acid Cleanser or Milk Cleanser sits in a similarly accessible price bracket, running a full, proper double cleanse routine both morning and night remains a genuinely affordable habit - not the expensive, multi-step luxury routine double cleansing sometimes gets framed as.

It’s also worth remembering the balm’s versatility doesn’t stop at cleansing. As mentioned earlier, it can double as a 10-minute nourishing mask when your skin needs a bit more, and its gentle, barrier-supporting formula also makes it suitable as a soothing shaving balm - one product quietly doing several jobs, which only improves its real-world value further.

With the routine context now clear, it’s worth zooming out and asking a fair question: how does this value proposition actually compare to the wider UK cleansing balm market? That’s the comparison worth making next - not product versus product, but value logic versus value logic.

How It Compares to Other Cleansing Balms on the Market

We’re not going to name names here, and that’s a deliberate choice rather than an oversight. The goal isn’t to pick apart specific competitor products - it’s to help you evaluate the broader “best cleansing balm” category with a sharper, more useful lens than price tag alone.

Here’s an honest observation about the UK cleansing balm market: a meaningful number of balm cleansers, particularly those positioned as premium or prestige products, sit at a noticeably higher price point, often for a similar or even smaller amount of product. It’s easy to look at a £30 or £40 balm and assume the higher price must reflect superior formulation, more effective ingredients, or a more luxurious experience. Sometimes that’s true. But price alone doesn’t tell you anything definitive about performance, and it certainly doesn’t tell you anything about cost-per-use.

This is where the value-per-use framing becomes genuinely useful rather than just a clever marketing angle. A £35 balm in a 100ml pot might sound reasonable until you actually do the same maths we did earlier in this piece - working out the grams-per-use and dividing the total price by the realistic number of cleanses you’ll get. In many cases, a higher sticker price does translate to a higher cost-per-use too, not a lower one, simply because the increase in price often outpaces any increase in product volume or usage efficiency.

Format plays a real role in this comparison as well, and it’s worth repeating because it’s one of the most overlooked factors in cleansing balm value. A tube format, like the one the Oat Cleansing Balm comes in, offers more hygienic, controlled dispensing than a pot - you’re not dipping fingers in repeatedly, which matters both for product integrity and for avoiding taking more product than you actually need out of habit. It also means significantly less product gets wasted at the end of its life, since you can squeeze a tube to access every last bit in a way that’s simply not possible with a jar. Our dedicated piece on why cleansing balms should come in a tube rather than a pot explains this in more depth, and it’s directly relevant here because that format decision has a measurable effect on real-world cost-per-use, not just a hygiene talking point.

None of this is about suggesting that higher-priced balm cleansers are poor products - many are well-formulated and loved for good reason. The point is simply that an honest comparison has to look past the number on the shelf price and into what you’re actually getting for it. That’s the comparison INKEY is built to win on, because the formulation decisions behind the Oat Cleansing Balm - from the specific oat-based actives to the tube format itself - weren’t made to hit a budget price point by cutting corners. They were made deliberately, with proven ingredients at concentrations that do a real job, priced in a way that reflects our wider belief that effective skincare shouldn’t be gated behind premium pricing.

That’s really the heart of the comparison: this isn’t a budget alternative pretending to be something it’s not, and it isn’t a premium product charging a premium simply because it can. It’s a clearly engineered formula, priced honestly, and backed by maths you can check yourself.

With the market comparison covered, it’s worth clearing up a handful of the specific, practical questions readers tend to search for before making a decision - the kind of detail-level questions that a broader comparison section doesn’t always have room for.

The Bigger Lesson Behind the 15p

Fifteen pence per cleanse isn’t really the headline here - it’s the evidence for a bigger point. Effective skincare, built on ingredients that are properly explained and dosed at levels that actually do something, doesn’t have to come with an inflated price tag attached. That’s not a slogan; it’s a maths problem we just walked through together, line by line, using nothing but the tube’s price, its size, and a realistic estimate of how much product a single cleanse actually requires.

The wider belief sitting underneath this blog is one we hold across our entire range, not just this one product: good skincare should be accessible to the people who need it, not reserved for those who can afford premium pricing on the assumption that cost equals quality. A £15 cleansing balm that genuinely dissolves makeup and SPF, soothes sensitive skin, and supports the moisture barrier isn’t a compromise - it’s proof that formulation decisions, not price inflation, are what actually determine whether a product performs.

The most useful habit you can take from this isn’t really about this specific balm at all. It’s the lens itself - looking at cost-per-use and ingredient transparency rather than sticker price alone, the next time you’re deciding what belongs in your routine and what doesn’t.

If you want to feel that value for yourself rather than just read about it, you can shop the Oat Cleansing Balm, 150ml directly. And if you’re looking to build out a complete, considered routine around it rather than adding a single product in isolation, our complete guide to double cleansing is the best place to start. Because at The INKEY List, we give a care - about what’s in the formula, what it costs you to use it, and whether both of those things actually add up.
