L'Oreal Infallible 3-Second Setting Spray Review: Why UK Buyers Keep Arguing Over the Smell
One buyer fell off a boat into Lake Windermere and reported her foundation had not moved. Another threw the can away after a single use because her chin broke out in a scaly rash. Same £9.03 aerosol, opposite verdicts. Here is what 100 recent reviews of L'Oreal's UK bestseller actually say.
One reviewer fell off a boat into Lake Windermere fully clothed, emerged soaked through, checked her reflection, and reported her foundation had not moved one millimetre. Her review has eight helpful votes. Another buyer, two months earlier, threw the bottle away after a single use, complaining her face felt tight and her chin broke out in a scaly rash.
Those two reactions, from the same £9.03 can of aerosol mist, tell you most of what you need to know about L'Oreal Paris Infallible 36H Setting Spray. This is the UK's number one setting spray by sales volume, it pulls a 4.4 average from over 7,000 Amazon reviews, and 62 of the 100 most recent reviews we read gave it five stars. It also carries one specific complaint that comes up so often you cannot ignore it. We went through the reviews to find out whose face this spray is made for, and whose it absolutely isn't.
What You're Actually Buying for £9.03
The Infallible 3-Second Setting Spray comes in a 75ml aerosol can, not a pump-action mist like the MAC Fix+ or Urban Decay All Nighter bottles most people picture when they hear "setting spray". That distinction matters, and we'll come back to it.
L'Oreal claims three specific things on the can: your makeup sets in 3 seconds, it lasts up to 36 hours, and it's transfer-proof, sweat-proof, and non-sticky. You hold it 30cm from your face, shake it, and mist in a circular motion. One pass covers the whole face. The 75ml size is the compact version; an XL exists too, and several regular buyers in the reviews mention switching up to it once they decided they loved the product.
At £9.03 it sits roughly where you'd expect a drugstore setting spray to land. Maybelline's Lasting Fix sits a little cheaper. Urban Decay and Charlotte Tilbury's versions both run three to four times more expensive. The interesting comparison point, though, is hairspray, which we'll get to in a second.
The Lake Windermere Test and Other Performance Stories
The best review on the page, and the one with the highest helpful-vote count in our sample, belongs to a buyer who titled her five-star writeup "Cry proof, lake proof, LIFE PROOF!". Through what she calls "a series of poor nautical decisions" she was launched off a boat and fully submerged in Lake Windermere. When she resurfaced, she checked her reflection expecting to grieve her makeup. Her exact words: "Foundation: cemented. Mascara: emotionally stable. Brows: still employed."
She is funny, but she is not the only buyer reporting extreme durability. A nurse wrote that she sprays it on before a 12-hour night shift and her makeup is still in place when her shift ends. An office worker described working 8 to 6 in makeup that "doesn't look cake" by evening. Another buyer bought it for a funeral, used the leftover for a summer wedding, and mentioned she'd sprayed a tiny bit on her collar too to stop foundation transfer.
The pattern across the 62 five-star reviews is consistent. People who have humid commutes, long shifts, emotional events, and sweaty conditions keep coming back to this product because their face survives the day. Whatever else you want to say about the formula, the staying power is real.
About That Hairspray Smell
You cannot read the review page and miss this. Somewhere between a third and half of buyers mention the scent, the texture, or the sensation of spraying something that feels distinctly like hairspray on their face.
The comments range from lightly amused to furious. A positive five-star reviewer cheerfully titled her post "Face hairspray 5*". A four-star reviewer described it as smelling "like a pile of dead leaves" and said the smell stays all day, then still gave it four stars because the product worked so well. A one-star buyer wrote it "feels and smells like hairspray. It feels tight on the face which is unpleasant". One reviewer who liked the product noted the smell is strong but "doesn't stay". Another wrote hers stung her eyes through closed eyelids.
Why the comparison? Aerosol setting sprays are fundamentally different beasts from pump mists. They use a propellant and tend to contain higher levels of alcohol to help the formula flash-dry in 3 seconds. That alcohol is what gives the sharp scent and what explains the tight feeling on the skin right after application. Pump-action setting sprays feel watery. This one doesn't, and if you've never used an aerosol mist before, the first spray will surprise you.
The Skin Reactions You Should Take Seriously
A smell you can get used to. A skin rash is different. Among the 14 one-star and 6 two-star reviews, a handful mention actual physical reactions: dryness, tightness, flaking, eye stinging, and in one case a scaly chin rash that took weeks to clear.
One reviewer wrote: "it has bought my chin out in an horrendous scaly rash that's taking weeks to clear up. I would avoid this product as I have since noticed others have experienced the same issue." Another complained of fumes that felt close to toxic. A third said the alcohol content dried her skin when used daily.
Against that, several buyers with sensitive skin reported no issues at all. One wrote: "I have sensitive skin so careful about what products I use on my face. I haven't had any problems with this fixing spray." She mentioned running the ingredient list through an app and getting a clean result. Another pale, sensitive-skinned reviewer reported zero irritation even with repeated layering.
The pattern, reading carefully: people who react usually react fast, within one or two uses. People who tolerate it can use it daily for long periods. If you have reactive skin or broken skin, patch-test on your jawline before committing to a full-face spray. And don't layer it repeatedly on eyelids; a couple of reviewers mentioned dryness there specifically.
The Bottle Defects Nobody Talks About
Buried in the one-star pile is something worth flagging: a small number of buyers received faulty cans. One ordered two bottles and both sprayed backwards out of the nozzle when used, spraying all over the hand instead of the face. Another received a bottle that was unsealed and appeared used. Amazon reportedly refused a return on the faulty aerosol.
This is rare, maybe 2 or 3 in 100 reviews, but it's worth knowing. If you can, buy during an Amazon price drop (one reviewer bought at £8 before Christmas) and give the nozzle a test spray into the air before spraying near your face. If the propellant is damaged or the can is compromised, you'll know on the first push.
How to Actually Get the Best Out of It
A few small details from the reviews add up to a real difference in results.
Hold the can at least 30 centimetres from your face. That's further than you think, roughly an arm's length. Sprays held too close concentrate too much product in one spot, which is how you end up with the crumbly, cakey finish a few one-star reviewers described. One buyer complained her makeup "came off" when she touched it with a tissue after 20 minutes; that's often a sign of over-application, not product failure.
Spray in a circular motion across the whole face, one pass. Don't layer immediately. If you want extra hold for an event, let the first layer dry for a minute and go again.
Cover your hair. Several reviewers, including positive ones, mentioned the spray will set your hair exactly like a hairspray will, whether you wanted it to or not. Towel over the hairline, or spray before you do your final hair styling.
Close your eyes and hold your breath briefly. A few reviewers with sensitive eyes or noses found the aerosol cloud harsh. Spraying in a well-ventilated room helps. So does the full 30cm distance, more than you might expect.
One clever trick from a regular buyer: she sprays her face before applying makeup AND after. Calls it "the holy grail". The pre-spray gives the foundation something to grip, the post-spray locks it. It's not official instructions, but it's a reviewer-tested workflow.
Our Rating and Who Should Actually Buy It
We're giving the L'Oreal Paris Infallible 3-Second Setting Spray a 4.2 out of 5. The performance is excellent when it works. The price is sensible. The bottle size is decent and the XL option gives you room to stock up. The one-star reviews are real, though, and the smell-and-aerosol debate is a dealbreaker for maybe 1 in 5 buyers.
This is the right buy for you if: you have long days, commutes, sweat, humidity, or emotional events where your makeup really does need to stay put for 10 to 14 hours. It's right for you if you've used aerosol hairsprays for years and aren't bothered by the feel. It's right for you if you're swapping up from a pump-action fixing spray that stopped doing enough.
Skip it if: you have reactive or broken skin, you live somewhere you can't ventilate your bathroom, you hate strong aerosol smells, or you're looking for a dewy pump-spray that feels like mineral water. This product is not pretending to be that. It's a serious lockdown spray, and the formula reflects that.
The reviewer who fell in the lake had it right. This is a sealant, not a spritz. If that's what your day demands, at £9 it's hard to do better.
