“You’re squinting again, Rae.”

“I’m trying to find the math. It says ninety percent.”

“Ninety percent of what? The surface area of the jar? The likelihood that we’re being lied to?”

“It says ‘up to’ ninety percent reduction in dryness. I’ve been using it for fourteen days and I still feel like a piece of parchment.”

“The ‘up to’ is doing all the work. It’s the smallest word on the bottle but it’s the most expensive one you’ve ever paid for.”

Rae turned the jar over in her hand. It was a heavy glass vessel, frosted to suggest a cool, clinical efficiency. The label was printed in a serif font that looked like it belonged in a pharmacy from the nineteenth century, but the ingredients list in the back was a dense thicket of six-point Helvetica.

She had bought it because the number 90 was large, gold-foiled, and centered. It looked like a grade, a score, a promise of a finished task. After two weeks, her skin felt exactly as it had before-tight, slightly flaky around the nostrils, and impatient.

The Psychology of the Best-Case Scenario

The phrase “up to” is the great magician of the consumer world. It creates a ceiling that the mind immediately mistakes for a floor. When we see “up to 90% reduction,” our brains, weary from the day and desperate for a solution to the mirror’s morning critique, discard the “up to” and the “reduction” and latch onto the 90.

We buy the best-case scenario. We pay for the outlier. In the world of skincare formulation, where I have spent the better part of a decade staring at stability tests and rheology reports, “up to” is the legal bridge between a marketing department’s dreams and a lab’s reality.

It is a technically true statement that encompasses a vast ocean of failure. If a study of 34 participants shows that one person had a remarkable 91% improvement in skin hydration-perhaps because they finally started drinking two liters of water a day or because their skin chemistry happened to resonate perfectly with a specific humectant-the company can legally claim “up to 90%.”

The fact that the other 33 participants saw a negligible 4% improvement or, in some cases, a breakout of contact dermatitis, is buried in the raw data that no consumer will ever see. The “up to” includes zero. It includes negative numbers. It is a protective cloak for the average result, which is usually underwhelming.

I was wrong about this for a long time. Early in my career as a formulator, I believed that clinical trials were the gold standard of truth. I thought that if a paper said a peptide increased collagen production by 60%, it meant I would see 60% more collagen in the mirror.

I sat in sterile conference rooms in suburban office parks and nodded as data scientists showed me graphs with steep, aggressive curves. I didn’t realize then that the curves were often the result of “data cleaning” or the specific exclusion of participants who didn’t respond to the treatment.

A Mathematical Technicality

I remember formulating a “radiance” serum three years ago. We used a stabilized Vitamin C derivative at a 2.8% concentration. The clinical trial we cited was done by the ingredient supplier, not by us. Their trial showed “up to 74% increase in skin luminosity.”

When I actually looked at the methodology, the “luminosity” was measured by a machine that detected light reflection on a microscopic level. It wasn’t something a human eye could perceive in a bathroom mirror. We were selling a mathematical technicality, and I was the one who signed off on the formulation.

I felt a slow, creeping rot in my professional pride that day, not unlike the time I discovered mold on a loaf of bread I had just started eating.

It was a Tuesday afternoon. I had bought the sourdough from a bakery on the corner of Bond Street. The crust was dark, blistered, and smelled of toasted grain. I took a large bite, savoring the tang of the fermentation.

It wasn’t until I went for the second bite that I noticed a small, fuzzy green patch tucked into one of the air pockets near the center. The exterior was a masterpiece of artisanal promise; the interior was undergoing a quiet, biological decay.

That is what “up to” feels like once you understand the mechanics of the claim. It is the green fuzz hidden inside the golden crust of the 90% promise.

There Is No Poetry in an MSDS

In the lab where I work now, the inventory is precise and unadorned. There are rows of 500ml glass beakers. There are stainless steel spatulas of varying lengths. There is a digital pH meter that requires calibration every morning at 8:15 AM using three different buffer solutions.

There are shelves of raw materials: Glycerin, Stearic Acid, Cetyl Alcohol, and various botanical oils. Each one has a Material Safety Data Sheet (MSDS) that lists its boiling point, its flash point, and its potential for irritation.

There is no poetry in an MSDS. There are no percentages listed in gold foil. There is only the physical reality of the substance.

When you move away from the “up to” theatre, you find yourself looking for ingredients that don’t need a lawyer to explain them. You look for substances that have a physiological affinity for the skin. This is why tallow has seen such a resurgence among people who are tired of the statistical games. Tallow isn’t a complex chemical puzzle designed to hit a specific “luminosity” metric; it is a lipid profile that looks remarkably like our own sebum.

The Radical Honesty of Weight and Volume

I spent an afternoon last month reviewing the production of a whipped tallow balm in a facility in New Zealand. The process was rhythmic and transparent.

The tallow was rendered from grass-fed cattle, filtered until it was a clean, ivory solid, and then whipped with jojoba oil and cocoa butter. There was no centrifuge running at 4,000 RPMs to force an emulsion of water and oil that didn’t want to be together.

There were no synthetic polymers added to give the illusion of smoothness. The texture was the result of the fatty acids cooling at a controlled rate while being aerated by a large stainless steel whisk. It was a product of weight and volume, not of percentages and disclaimers.

The facility itself was organized with a strict, almost military logic. The floors were grey epoxy. The walls were white tile. Every jar was filled by a machine that used a piston to dispense exactly 100ml of product. A worker in a white lab coat and a blue hairnet inspected every tenth jar to ensure the seal was airtight.

There were no posters on the walls promising “90% reduction” in anything. There were only logs of temperatures and batch numbers. It was a place of work, not a place of persuasion.

We are conditioned to want the big number because we are afraid of the incremental progress. We want the “90% reduction” because it suggests a transformation that is almost total. But skincare isn’t a transformation; it’s a maintenance of a biological barrier.

Your skin is a wall, not a project. When you coat that wall in synthetic silicons and “up to” promises, you are often just painting over the cracks without addressing the mortar.

Rae put the glass jar back on the shelf. She looked at her reflection in the mirror, the one that didn’t have a 74% luminosity increase.

“What are you going to read instead?”

“The list. The actual stuff. If I can’t understand what it is without a degree in organic chemistry, I don’t want it on my face at 7:00 AM.”

“It’s a shorter list,” I said. “And there are no fish in it.”

She laughed, but there was a sharpness to it. We have all been the mark in the “up to” game. We have all paid the premium for the ceiling and lived in the basement of the results.

The cost of that word-those two tiny, insignificant syllables-is measured in the billions of dollars spent on products that do exactly what they legally have to do and nothing of what they practically promised to do.

When I formulate now, I think about that moldy bread. I think about the betrayal of the first bite. I think about the clarity of a substance that doesn’t need to hide behind a statistical outlier.

The industry will continue to use the “up to” loophole because it works. It preys on the part of the human brain that hopes for the miracle while ignoring the fine print. But once you see the green fuzz in the center of the sourdough, you can never go back to just looking at the crust.

You start looking at the ingredients. You start looking at the source. You start looking for the honesty that doesn’t require a percent sign to prove it exists.

The transition to a simpler regimen isn’t about being “natural” in some vague, hippy-dippy sense. It’s about being precise. It’s about recognizing that a jar of fat and oil, properly prepared and honestly sold, is worth more than a thousand clinical trials designed to find the one person who got lucky.

It’s about buying the reality of the product, not the fantasy of the number. And in a world of “up to,” reality is the most radical thing you can put on your shelf.
