This is the first match of the first round in my setting spray showdown series, where I’m testing popular formulas side by side to see what actually makes a difference in real life. I’ll be doing the same makeup, with same lighting, for at least 16 hours for each test. I’ve also been testing all of these setting sprays for months before doing these elimination rounds. For this round, I tested One/Size On ’Til Dawn Mattifying Setting Spray on one side of my face and Charlotte Tilbury Airbrush Flawless Setting Spray on the other.

Right away, I could see a literal line down the middle of my face. It’s very apparent that these are very different formulas. The One/Size side locked in immediately with a blurred, soft-matte finish, while the Charlotte Tilbury side stayed wet and shiny for a while. Even after fanning it because it wouldn’t dry down, it still stayed a little too dewy. The One/Size side looked like my skin but smoother, while the Charlotte Tilbury side had that slightly glassy, almost plastic-like sheen. The One/Size has more of an intense aerosol type sprayer while the Charlotte Tillbury has that spitty spray bottle situation. I don’t actually love either mechanism and wish they had one of those fine misters.
A couple hours in, the difference got even clearer. My blush and bronzer honestly looked better on the One/Size side, and it was smoother, more even, and less textured. The Charlotte Tilbury side was still a bit sticky and shiny, and while both sprays definitely helped my makeup last, the One/Size side felt lighter and more comfortable throughout the day.
At the 12-hour mark, I couldn’t believe how good both sides still looked and that even my cream blush, bronzer, and eyeshadow were totally intact. The makeup on my nose hadn’t budged. I asked people at an event in the afternoon which side looked better(they didn’t even know what was different on each side), and every single person (including my husband) picked the One/Size side. He said the Charlotte Tilbury side looked a little “clumpy,” and honestly, I agree. It also still felt heavier by comparison.
By the 16-hour mark, both sides were still going strong, but the finishes had shifted a bit. The One/Size side looked a touch more dry and flat. Even though it still matte and blurred, it was maybe too matte at this point. The Charlotte Tilbury side, meanwhile, had settled into a softer, dewier finish that was actually a little more flattering right at the very end of the day.
Who’s moving on?
If you want that locked-in, blurred, weightless matte finish that doesn’t move all day, One/Size On ’Til Dawn is the clear winner. If you prefer a more dewy, natural look (and don’t mind a bit of shine or heavier feel), Charlotte Tilbury Airbrush Flawless still holds up impressively well. I’m honestly shocked that after 16 hours, my makeup looked almost exactly the same as when I started. This experience was the same as when I’ve been testing this before, and I’ve found that both do a great job. The One/Size side just looked a little more flawless all day and has held up better not just in this test but when I’ve testing them running on the treadmill, playing with my son, and out in the summer heat and humidity. One/Size moves on!
