I’ve used this product for a few days, trying to make it work, but it simply does not live up to its claims. I have extremely oily skin, and was excited to try such a promising product being that most products targeted towards oily skin are not evolutionary or fulfilling in their promises. This one, unfortunately, is one of those. To begin, application for this product is quite finicky and doesn’t work well with skincare such as sunscreen or dewy products. It leaves a white cast on my medium complexion and pills with some of my foundations. However, it does leave a matte finish initially after finishing and setting my makeup. Most disappointing, though, is the longevity. The “12 hour” promise is more like 3 hours on my skin…which, on a normal day at the office, is ... MoreI’ve used this product for a few days, trying to make it work, but it simply does not live up to its claims.

Overall, I don’t see anyone who truly has oily skin benefitting from this much more than what you’ve already been using. Maybe one day there will be a solution to our excessively oily faces!

I have to start this by stating that I do not write reviews, ever. But after trying this product I couldn’t not share. My face has always been extremely oily from everywhere. I have tried every product out there that says mattifying on it. I have mattifying moisturizer, mattifying primer, matte foundation, and mattifying setting spray. As you can tell, being oily is a huge problem and even with all of this my makeup won’t last all day and within a few hours after application my face would be oily. Since the first day I tried this oil sucker primer I could tell it was gonna work. I went all work day (11hrs) and my makeup was intact and no oil/shine at all. Nowhere to be found, just a fresh face of makeup on till I removed it at the end of the day. The amount of joy ... MoreI have to start this by stating that I do not write reviews, ever.

I even can get in the aquatic pool at work and as long as my face doesn’t touch the water then my makeup stays intact and again, no oil/shine. I am blown away at how good this works. This for sure will be life changing for me because for years it has been a struggle and yes it affects my self confidence, especially when people would think I was sweating and they would ask but it was just my oily face. So if you are having doubts about getting this, don’t, it really does work amazingly well. Probably the only mattifying product out there that actually does. I will say, follow the instructions on how to apply because you can get the white cast/spots but it goes away once you blotch it with a damp finger. I love this and I hope that this product is never discontinued cause I will need it for the rest of my life.

Honestly I’m impressed. My normal routine sets me pretty well but I can feel very dry by the end of the night as I prime, spray, powder, spray and powder to ensure my face stays matte. This primer does the work without extra steps. Given I do still use a setting spray the primer beats a lot of other ones in maintaining a matte face. The ingredients are amazing for the skin such as Korean red ginseng and hyaluronic acid, really helps with preventing your skin from feeling cakey and dry. (Given I have a solid skincare routine) The primer on its own will last a few hours and you might see a little shine at the end of the night but a full face with power and/or spray you’ll be matte all day long no questions asked.The only reason I’m deducting a star is because of the ... MoreHonestly I’m impressed.

They’re very meticulous and if you’re unable to follow the steps precisely you won’t be utilizing this product correctly. This primer isn’t for a quick go to looks at all as it requires a 3 minutes drying period with no facial movement (they’re not kidding you can’t move your face while it dries) and if you have any white cast areas you have to gently massage it with a damp finger. It comes with a small pamphlet which is helpful.

At first, I was letting it dry for 3 minutes as the directions states and it would leave a dry patch on my face when I would put my make up on. Even setting spray wouldn't clear it up so I stopped using it for a month until I came up with a plan. I didn't want to throw it away yet as I heard only good stuff about this primer so I didn't want to give up yet. Especially I have oily skin so I had a strong feeling this would work because it says "oil sucker".I decided to change it to letting it dry on my face for 10 minutes instead and WOW what a difference it made. Doesn't leave a dry patch anymore. When I apply my make up on afterward, the primer blends in with my skin so well as I was nervous it would look bumpy / dry underneath my make up after drying. I have VERY ... MoreAt first, I was letting it dry for 3 minutes as the directions states and it would leave a dry patch on my face when I would put my make up on.

I have VERY oily skin and my face doesn't get oily anymore during the day with this primer. This primer is so good and i'm so satisfied I finally found a primer that controls my oily skin as I have tried other primers and it hasn't worked. Sometimes I have long days where I am out from 7 am - 6 pm and my face still looks flawless as if I just done it. The matte look lasts all day, literally! 100% recommend !
I have a very oily t-zone. I oil up literally after 1 to 2 hours even with the use of any high end primers. I also live in a very hot and humid country, yes, the Philippines, and iyk, yk. When I first saw this on Tiktok, I got so excited cuz I was thinking that this would be my ONLY hope to control my very active sebacious glands. As desperate as I was after seeing a positive review of a Filipino cosmetic vlogger, I hurriedly purchased one for myself. I followed every single package instruction as carefully as I could— from applying it very thinly to a completely dry skin to making an expressionless face for three whole minutes until it dried down, and so on. I thought it was so good at first. But I noticed it started peeling off a little bit the moment I applied my ... MoreI have a very oily t-zone.

I thought it was so good at first. But I noticed it started peeling off a little bit the moment I applied my foundation using a brush with very light tapping motion (no swiping). I tried troubleshooting it and made it work. I noticed oiling up after 4 hours. But after a few hours more, my skin looked patchy and scaly especially around my nose and my nose area, which does not usually happen to me when I’d use a different primer. So I don’t know. Take note: I always do skin prep and would wait 5 mins or more before I apply my makeup.
As someone who frequently gets an oily t-zone, especially during the warmer months, I was thrilled to try the newly launched Oil Sucker Extreme Mattifying Alkaline Primer from ONE/SIZE. Let me just say that it definitely does what it says it does and more! This long-lasting primer has a gel-like texture that feels cool and lightweight when applied to the skin. Quickly though, as you let it set for 3 minutes after applying, you can feel a slight tightening effect to the skin. By the time the primer has set you can visibly see a matte finish and blurred pore appearance which helps deliver a smooth and flawless finish after you apply your foundation and other makeup. It definitely has that drying / extremely matte effect, so I would highly recommend only using if you ... MoreAs someone who frequently gets an oily t-zone, especially during the warmer months, I was thrilled to try the newly launched Oil Sucker Extreme Mattifying Alkaline Primer from ONE/SIZE.

This review is long overdue. I was recently in Tokyo for some holiday/family time and decided to pick this up in anticipation of the heat and humidity. I have naturally oily skin so my skin is extra shiny in the summer. I made sure to read the instructions and reviews on this before I used it the first time to make sure I used this product as was intended. My process for application was primer > sunscreen > eye cream > foundation. I had to cut out the moisturizer step in order to make sure this product didn’t pill on me but a few weeks of this was no big deal.The primer kept my makeup on ALL day and on the occasional nights I fell asleep with my makeup on, everything was still in tact the next day. It’s important to note that my makeup never felt dry or flaky ... MoreThis review is long overdue.

I have extremely oily skin. I'm going to Vegas for my 52nd birthday and was looking for something to make my makeup STAY. I read the reviews, watched the tiktoks. I just got this in. I started by washing, serum, etc. Then I really shook the product for a minute or so, then applied a bunch all over my face (cuz a lot came out). I put it on my eyelids, by my nose, on my cheeks, everywhere. I "flicked" it like an influencer said to do but I don't think that was necessary. Then I applied all my makeup as usual, then forgot about it, til now = bedtime. Today I worked out at noon, then golfed after work, then cleaned my apt. I sweated at the gym. I went golfing about 11 hours after I woke up, no touch up, no washing, no powdering my nose. And I took a look. The only thing ... MoreI have extremely oily skin.

I went golfing about 11 hours after I woke up, no touch up, no washing, no powdering my nose. And I took a look. The only thing that was really oily was the tip of my nose, but then it always is. My cheeks and forehead are usually oily, and my eye makeup is usually gone. NOPE. They stayed. I have found my holy grail. I will say, I also used the ONE/SZ powder and setting spray as well, and maybe it was all three together, or maybe just this product, but man, I haven't been so impressed by products meant for oily skin in a long time. Well done! I am now going to read the reviews on his foundations because if the primer, powder and setting spray work so great, the foundation must be amazing too. I recommend. I also will say, you do have to do all the shaking and applying properly, but it's worth it to have makeup stay all day. So happy!
i hate to be the first one star review here but i have to let the oily betches know!!! i had high hopes coming into this product because i know if someone will come out with the most matte oil sucking primer, it would be none other than miss patrick starrr. however, this primer was so hard to use. first, there was such a bad white cast and i know that the instructions say to tap it away with a damp finger but although that helps get rid of it initially the white stuff immediately comes back and starts pilling. i am using a water based tinted moisturizer and i followed all of the instructions but when i was blending it in, small beads started to show up on my face. also just wanted to point out that when people say that the primer is very tight feeling, they were not ... Morei hate to be the first one star review here but i have to let the oily betches know!!! i had high hopes coming into this product because i know if someone will come out with the most matte oil sucking primer, it would be none other than miss patrick starrr. however, this primer was so hard to use. first, there was such a bad white cast and i know that the instructions say to tap it away with a damp finger but although that helps get rid of it initially the white stuff immediately comes back and starts pilling. i am using a water based tinted moisturizer and i followed all of the instructions but when i was blending it in, small beads started to show up on my face. also just wanted to point out that when people say that the primer is very tight feeling, they were not wrong. it feels like a clay face mask that has been sitting on my face for 3 hours. this primer did NOT keep me matte throughout the day (i have a very VERY oily t-zone that will literally look shiny in an hour not even in heat) and i found myself still needing to touch up every hour or so. personally, i think that the milk makeup pore eclipse primer works the same or even better than this one while at the same time being way easier to use (though i will say, the milk primer does pill slightly but its not too much) and you get more primer for the money. sorry oily gworlz, this ones a flop!
The ONE/SIZE Beauty Oil-Sucker Primer provides a strong, mattifying hold. If you have acne-prone and oily skin like me, this primer is what you need this summer to keep your makeup from melting. No need to worry about whether it will feel tight on the skin, as there is no tightness afterward. I like how you can feel how matte yet soft your skin is after you apply your makeup. This is going to be my holy grail for the summer! It has a smooth texture and sits really nicely underneath my makeup. I feel like it makes my makeup last all day. I follow all the rules on how to use this primer, and I must say my makeup never looked so good. So after I prep my skin, I shake the primer well and then apply the primer to my face.
