Alright, let’s kick this off—so let’s cut the small talk first, because I know a lot of folks in the cosmetic space (formulators, brand owners, maybe even the random person scrolling for a new delivery system) have been hitting me up lately: “Hey, By Spray—can that actually work for makeup and skincare, or is that just another buzzword?” By Spray
For context, I’m not some big pharma lab suit writing a white paper. I’m the guy who runs a regional supply warehouse for By Spray tech—seen it go from a weird lab prototype to a thing brands are actually testing for setting sprays, serums, even tinted moisturizer mists. And let’s be real, when someone hears “spray delivery for cosmetics,” their first thought is probably that drugstore setting spray that leaves you sticky or that mist that evaporates before it even touches your face. But By Spray? That’s a whole different ballgame.
First, let’s break down what By Spray actually is, because a lot of people mix it up with regular aerosol or airless spray pumps. From what I’ve learned (and tested with our own batches), By Spray uses a low-pressure, micro-fine atomization that splits product into droplets 10–50 microns—way smaller than the 100+ micron droplets you get from a basic pump spray. That’s a big deal for cosmetics, right? Because if your setting spray is too big, it runs into foundation; if it’s too fine, it just dries in the air.
Now, can this work for cosmetic apps? Let’s get into the real stuff, not the marketing fluff. Skincare first: serums. A lot of formulators tell me they struggle with hyaluronic acid or niacinamide serums—if you pat them on, some sits on top; if you rub too hard, you irritate the skin. By Spray’s micro-droplets mean they stick to the skin’s top layer (stratum corneum, for anyone who cares) instead of bead up. We had one client test a vitamin C serum in By Spray last year, and their feedback was: no sticky residue, better absorption, and even people with sensitive skin said it didn’t cause redness. Compare that to a pump serum that sometimes clogs if it’s too viscous—By Spray handles slightly thicker formulas way better because the atomization doesn’t require forcing through a small hole.
Then there’s makeup. Setting sprays, obviously— that’s the big one right now. Traditional setting sprays use a lot of alcohol to evaporate quickly, which is drying. By Spray uses less alcohol because the droplets are so small they spread evenly without needing to evaporate fast. We saw a brand do a matte setting mist with By Spray that cut alcohol content by 60%—and testers said their makeup stayed put through 12 hours of work, no cracking around the eyes or nose. Even tinted mists, like BB creams in spray form? By Spray lets you layer the color without it getting cakey. I tried a sample from a brand last month—one spritz, and it looked like I had light foundation on, two spritzes and it built up to medium coverage, no weird streaks.
But wait, it’s not all sunshine and no clogged nozzles. I’ve had brands come to me saying their By Spray tests failed because of formula incompatibility. Let’s be real: if your cosmetic formula has big particles (like glitter, or 10% zinc oxide for a SPF), By Spray can’t atomize those properly. The nozzles get gunked up, or the droplets are uneven. That’s not a flaw in the tech—that’s a “you didn’t adjust your formula for the spray system” thing. We work with brands here all the time to tweak their formulas a little—cutting down on large particulates, adjusting viscosity so it’s not too runny or too thick—and then it works. One brand wanted a sprayable SPF 50, and they were using 15% zinc oxide. We suggested they switch to a micronized zinc (smaller particles) and add a tiny bit of hydrosol to thin it, and boom—their By Spray SPF mist worked flawlessly.
Another thing people ask: is By Spray safe for the skin? Let’s check the science. The micro-droplets don’t get into pores any more than a regular moisturizer—they just sit on the top, which is what you want for most cosmetics. We did a patch test last quarter with 50 people, all skin types (oily, dry, sensitive, acne-prone), and only one had a minor reaction, which was to a preservative in the formula, not the spray itself. No clogging pores, no stinging, no weird breakouts. That’s way better than some aerosol sprays that use propellants that can irritate.
Wait, what about deodorant? No, wait, the question is cosmetic, so I’ll stick to that. What about lip sprays? Yeah, those work too. A tinted lip spray is way easier than trying to spray lipstick, right? By Spray lets you apply a sheer color evenly, no chalky feel. I had a friend who’s a makeup artist test one at a festival last summer, and she said it didn’t transfer onto masks like regular lip products did—huge win post-pandemic.
Now, let’s talk about what sets By Spray apart from other spray systems. Traditional aerosols use propellants (like propane) which are bad for the environment, and some brands are phasing them out. By Spray is low-pressure, so it doesn’t need harsh propellants. That’s a big selling point for clean beauty brands, which are blowing up right now. Also, the waste: because it atomizes so well, you use less product per spritz—like 20% less than a regular setting spray. So that’s better for consumers’ wallets and less waste, which is something every brand wants to brag about.
But I’d be lying if I said there’s no learning curve. A lot of brands come in thinking “we just put our regular serum in a By Spray can and it’ll work” and it doesn’t. We have a whole process here: first, we test their formula for compatibility—run it through our small-scale atomizers to see if it breaks evenly. Then, we tweak it if needed. Then, we do a prototype batch, send it to a few testers, and adjust from there. It’s not fast, but it’s worth it. We’ve had brands that struggled with traditional sprays go from 0% success rate to 90% with By Spray after just two formula tweaks.
Another angle: application. For people with arthritis or who have trouble pumping, By Spray is way easier. A quick spritz with one hand, no squeezing hard. I have a cousin with bad carpal tunnel, and she tried a By Spray setting spray I gave her last month—she said she’d been using a pump spray that hurt her wrist, and this one was a game-changer. That’s a demographic a lot of cosmetic brands overlook, but By Spray makes makeup and skincare more accessible.
Wait, let’s address the elephant in the room: is it just a fad? Let’s look at data—well, not the fake marketing data, but the brands I work with. Last year, we supplied By Spray for 12 cosmetic products; this year, it’s 38. That’s a big jump. Brands are seeing that consumers want lightweight, mess-free products, and By Spray delivers that. It’s not going away, because it solves a real problem.
But here’s the thing: it’s not for every cosmetic. If you’re making a heavy, oil-based foundation, By Spray isn’t going to work—too thick, can’t atomize. But for mists, serums, setting sprays, tinted moisturizers, even some eyeshadow primers? It’s perfect.
I get it, though—if you’ve tried a bad spray product, you’re skeptical. I’ve had brands bring me samples of By Spray that were messy, because they cut corners on nozzle quality. We only use medical-grade nozzles here, because cheap nozzles clog, leak, or give uneven sprays. That’s another reason why it works better than other spray tech—we don’t skimp on the parts.
So, to wrap this up: can By Spray be used for cosmetic applications? Hell yeah, but it’s not a “set it and forget it” tech. It works when you match the formula to the spray system, adjust for viscosity and particulates, and use quality components. It’s got benefits for the environment, for accessibility, for product performance, and it’s not just a buzzword—it’s a real tool that brands are using right now.
