Here is the puzzle. Evie Kirk wore this primer through a heatwave and called it "the best primer I've ever used." Zoe went indoor skydiving in it, fully expecting her makeup to slide off, and it held. Then there is Charmed1, who tested it before a concert: "as soon as I sweated a bit on my hairline my make up was coming off." Same product, same £9.59, opposite outcomes.

The Maybelline New York Grippy Serum Makeup Primer is one of those viral drugstore launches that the internet decided was a holy grail before most people had tried it. It carries a 4.6 rating across 1,696 buyers, so the crowd clearly leans positive. The catch is that this primer behaves very differently on different faces, and the reasons trace straight back to how it is built. So instead of a tidy pros-and-cons list, we are going to follow the disagreements, because that is where you will find out whether it will work on yours.

What "serum-to-grip" actually means before you buy

Most primers pick a lane. Silicone primers blur and fill; tacky grip primers give your foundation something to cling to. Maybelline's pitch with Grippy Serum is that it does both, by changing texture on your skin. You apply it with a glass dropper, pat it in with your fingertips, and wait. The brand calls this Serum-To-Grip technology, and the instruction that matters is the 20-second pause: a fresh, watery serum texture is supposed to transform into a tacky grip layer in that window, before you put any makeup on top.

That 20-second transformation is the whole product, and skipping it is the single biggest reason results swing. It goes on like a lightweight serum, then sets into something foundation can hold onto. The official claims are specific: up to 24 hours of grip, up to 24 hours of hydration, instantly plumped and hydrated skin, no white cast, no pilling, a vegan and water-based formula, and non-comedogenic. It is a 30ml glass bottle for £9.59, suitable for all skin types.

The second active is the part people skim past: 2% niacinamide. The way I read it, a bare grip layer could easily feel tight and dry through a full day of wear, so the niacinamide is there to keep the skin hydrated through that wear time. The source claim is simply that the 2% niacinamide helps the formula grip makeup while still hydrating the skin for 24 hours. Whether that balance lands is exactly what splits the reviews, so let's get into the fights.

Disagreement one: the people who got all-day hold, and the people who didn't

The biggest divide is about hold, and it really is a divide, not a quiet minority grumbling. On one side, the all-day camp is loud and specific. Manchester Miss timed it: "My makeup lasts literally all day from 7am to 10pm." Lauren Allsopp said her makeup "stays on literally all day without budging." Anna, who is prone to dry skin and separating makeup, layered moisturiser then primer and got through "9 hour shifts when I'm bartending and doing line dancing." These are not gentle desk days; they are sweat, movement and heat, and the primer survived them.

On the other side sit the people for whom it simply did not last. Sarah's review is two blunt lines: "It's okay doesn't keep makeup on all day though." Charmed1 lost hold at the hairline the instant they perspired and is going "back to the elf one." Blackpool_1983 split the difference in a way that probably describes a lot of real-world wear: "Make up was in place for 3/4 of my day but I was shiny in part by the end."

So what separates the two camps? Read closely and a pattern shows up. The all-day reviewers almost all mention a deliberate routine: skin prep, the 20-second wait, sometimes a hydrating layer underneath. The disappointed ones often describe heat and sweat as the breaking point. This tracks with a water-based grip layer: it is brilliant at holding makeup in normal conditions and against everyday oil, but heavy sweat is a different stress test, and not everyone's skin passes it. If your makeup routinely melts off in the heat, go in with managed expectations rather than the viral hype.

Disagreement two: "grippy" thrills some, repels others

The name sets up the second argument, because not everyone wants their face to feel grippy. For the fans, the tack is the magic. lauren put it plainly: "It does grip makeup, one of the best primers I've used." Carrie liked that it is "very sticky" and "keeps your makeup in place." emilia dekert described the satisfying sequence the formula is designed for: "It is sticky and then dries so it's still easy to apply your makeup on your face."

For the critics, that same stickiness is the dealbreaker. CrystalBerry found it "very sticky" enough that they had to wash their hands after applying. Mecca's experience went further: "I gave it a minute to dry then applied foundation. It actually pilled and looked awful. It took ages to remove." That pilling complaint is worth flagging precisely because Maybelline's marketing promises the opposite ("does not pill"), so if your skin or skincare combination doesn't agree with the grip layer, you will notice the gap between claim and result.

Then there is the camp that found it not grippy enough. This one surprised us, because it directly contradicts the people above. Emi Black, an oily-skinned user who otherwise likes it, said "the 'grippy' feeling is not as strong as I had hoped, maybe because it is a watery consistency," and reckons cheaper primers gripped harder. Amelia expected something more like "the Elf one." Clare went blunter: "i don't find this grippy at all unless I absolutely coat my face." The same watery, serum-first texture that makes it feel light to one person reads as underpowered to another. There is no neutral verdict on the grip here, only strong feelings in both directions.

Disagreement three: plumped and glowing, or pilling and broken out

This is where the 2% niacinamide and the serum framing get tested, and it is the most consequential split because it is about your skin, not just your makeup. The hydration camp is effusive. Gox noticed "a massive difference" and said that even at the end of a long day in makeup, "my skin still feels and looks great" with a glow left behind at removal. C, who has dry skin, said it makes their makeup "look so much smoother." Emily M used it to even out a dry forehead. Avid_Buyer_92 got the exact result on the label: "a smooth, plumped finish to the skin." For people whose makeup usually cracks over dry patches, the serum-plus-niacinamide approach is doing real work.

The minority report is smaller but it is the kind you need to hear before spending money. DU liked the grip but said it "broke me out since it was a bit thick on my skin." House Cat had a sharper reaction: the serum made foundation easier to apply, "only downside for me was that it has caused my face to blotch and swell so it's causing an allergic reaction." And a few people found the formula settled into texture rather than smoothing it. CrystalBerry said their makeup "still settles into any areas of dry skin" and even "breaks up in some areas that my make up does not usually." Css went all the way: "It also shows every single line and crack through concealer."

The takeaway here is about the odds. Maybelline calls this non-comedogenic, and most reviewers experienced it as hydrating and skin-friendly. But "non-comedogenic" is a formulation aim, not a guarantee for every face, and the thickness that gives the grip its staying power is the same thickness a small number of people found pore-clogging or texture-emphasising. If you are reactive or breakout-prone, patch test before a big day.

One thing nearly everyone agrees on: the value and the application

For all the arguing, two points draw a near-consensus. The first is price. At £9.59 this keeps coming up as the budget hero that embarrasses pricier options. Peter scott bought "an expensive il.makiage one which was good but this one is better for a fraction of the price." Shaz called it "so cost friendly." Ruth Cavell summed up the mood: "only need a little bit and my foundation stays on all day, well worth the money."

The second is how little you use and how nicely it goes on. Melanie noted "you don't need much at all." Watermelon wave appreciated that "it applies really well, not too runny or sticky," and that unlike thicker rivals it isn't "hard to get out of the bottle." sarahpurbrick made the same comparison: "not too thick and hard to spread like the elf one." The glass dropper bottle is part of the appeal, though it is not flawless: one buyer found the pipette "a bit hit or miss," and Nadine warned that "if it tips over it does leak a little." Store it upright and a 30ml bottle should last a long time given how sparingly people use it.

So which camp will you be in?

After weighing the arguments, the pattern is clear enough to make a call. This primer is a strong bet if you want a hydrating, lightweight base that grips makeup through a normal long day, if you have dry or normal skin that benefits from the serum-and-niacinamide hydration, and if you are happy to commit to the 20-second wait and a bit of skin prep. At £9.59 the value is excellent, and the people who follow the method tend to become repeat buyers fast.

Approach with more caution if your makeup melts in heat or heavy sweat, if you actively dislike a tacky finish, or if you have reactive, breakout-prone skin, since a real minority pilled, broke out or reacted. And if you are chasing the absolute strongest grip on the market, a few oily-skinned reviewers felt firmer-holding (and cheaper) primers existed.

Our verdict: this lives up to its reputation for most people, just not the universal-miracle framing it got online. It is a clever, well-priced serum-to-grip primer that does exactly what it promises for the majority, with a vocal minority whose skin or expectations it doesn't suit. Knowing which group you are likely in, before you buy, is the difference between a new staple and a returned bottle. For most readers it is an easy yes at this price.
