What the gurus are saying

Gurus consistently praise this spray for delivering a luminous, skin-like glow that sets makeup all day without looking sweaty or greasy. The standout strength is its ability to blur powder and flakiness back into the skin, making it especially valuable for dry or textured complexions. A recurring note is that application amount matters; using enough product unlocks the full glass-skin effect, while too little misses the payoff. There's strong consensus it outperforms matte alternatives and some use it pre-foundation or on eyeshadow.

"This is the One/Size Powder Melt Glass Setting Spray. This will truly give you glassy, dewy, glowy skin. If you're someone that's dry, you have flaky skin, you use a lot of powder-based makeup, and sometimes your skin looks dull, it looks dry because of the makeup, and you just want to get rid of that powdery, dry look to your skin, then this is the one to go with. This is going to give you glassy, dewy skin, but it doesn't give you greasy, sweaty looking skin. I really love having that glow and that dewiness to my skin, especially when I am drier, when my skin is a little bit flakier, then this is my go-to. If you do have flaky skin and after you've applied your makeup, you're starting to see it come through and your skin's starting to lift a little bit, this would be great to use on those days when you're flaky because I feel like this just melts the flake back into the skin and it just blends into your normal skin and then your skin looks fresh and skin-like again. This really helps to melt that flake back where it's flush on the skin and it's not noticeable."

THESE BEAUTY PRODUCTS EARNED A SPOT IN MY ROUTINE - SKINCARE & MAKEUP THAT DELIVERED!
"I just love the complexion that it gives. If I'm wearing just a tinted sunscreen with a little bit of blush and bronzer, I will still put this on top because it just makes my skin look so healthy and glowy and very glass-like, but without looking sweaty and greasy. It's well worth the money. It's 10 out of 10. It really does keep your full face of makeup in place for the entire day and all night until you wash your face at the end of the night. This is way better in my opinion than the original matte. But of course, if you love matte skin, then this would not be it."

My #1 Makeup RIGHT NOW 😍 (best of best)
"If you're wanting a setting spray to kind of add something different to your collection, I highly recommend checking out the One Size Powder Melt Glass Setting Spray. At first, when I tried this, I wasn't sure what all the hype was about, but I don't think I was using enough. When you spray a proper amount of this, it really actually gives you glass skin and also makes your makeup last. It's insane."
My FAVORITE Products from June 2025 😍
"This is the One Size Powder Melt Glass Setting Spray. I have this all over the skin. Can you see how like luminous it is, but it's not sparkly and it actually locks in your makeup. You don't get like a glow from an oiliness. It's like, you know how the Tatcha dewy Skin Mist, for example, the glow comes from like an oily base? This actually makes your makeup last all day long, but it melts everything and makes it look so much more skin-like. I am loving this. It's so good. I've been drenching my face like crazy in it basically every day, and I've noticed a huge difference in just the overall appearance of my skin and how like fresh it makes my skin look."
I LOVE how this look turned out!! 😍 Keep using what you have!!

Testing TONS of Hyped NEW Makeup! 🙊
"This powder melt setting spray, I feel like it looks really nice on the skin. I'm going to have to keep using it. This one has a little bit more of that glass skin finish. I'm excited to continue to play with this and maybe next time apply a little bit more and see how glass skin-like my skin can be if I really go overboard with this or spray a lot. I love the packaging and I really liked how it applied."

"The one from One Size does a really good job of just locking in your makeup. It has a very nice natural finish. It's not going to make you look too oily or too glowy. It's definitely not going to mattify you."

"I do really love the One Size Powder Melt Glass Setting Spray. I use that one in this step when I'm going to events and etc. If it was more of that, like, alcohol spray, like the One Size one, I would just do enough that my face feels covered. I don't want to wet my face completely because then you can get into some texture, like some dry texture. The product might sit in your brows, it might sit in your lashes, facial hair, you know."
