My best friend gave me a tube of oil mattifier for me to try few years ago, after I asked what did he do to accomplish such a flawless skin. He told me he first applies sunscreen, just the size of half an english pea on each cheek, forehead, nose and chin and blend it well. If you apply to much sunscreen, you will end up with "chalky" lines later. then, he just applies MK oil mattifier on his face. That is it! he says during the day, he will use some blotting tissue just to absorb the oil that his face will naturally produce no matter what he puts on it. The key is not to rub that tissue against your face, in fact, never rub your face with anything not even when you are washing it, as this will only irritate your skin and will produce even more oil. I take the word of a guy who looks amazing and natural, always and who seems not to age AT all. Needless to say, I am a big fan of MK oil mattifier, even though for me the effect wont last all day, but pretty much nothing will do so I don't mind reapplying or just blotting my face. I'm happy with the product

Works nice i guess, yet my skin is not that oily.

doesnt do much. its mattifies my skin for half an hour

It comes in a tube with a small opening, so there's no contamination. It works great! My T-zone is much less oily than without it. I even use a little on my eye lids instead of buying an additional eye primer, and it works really well to prevent creasing of my eye shadow. My shadow looks the same in the evening as when I put it on in the morning. I love this!

I've tried the mattifier but prefer the Oil Control Lotion. I apply it all over my face and have used it for over 3.5 years and recommend to all my friends (and customers) with combination to oily skin.

I unfortunately have really oily skin and realize that no matter how good a product is, it's not going to make my body stop producing oil. That said, my skin still gets oily with this mattifier. I use it before applying foundation and it offers a little moisturization and doesn't feel greasy. I like to think that it helps keep my skin less oily, but by lunchtime, my skin is as oily as usual. It helps a little at first, but nothing can keep up with my oil glands.

If you have normal or combination skin, this will probably work for you, which is why I'm giving it a 3 instead of a 2. If you're a grease ball like I am, then this probably won't be tough enough for you.

I love this stuff! It really works well for me. I use it under a powder foundation. It lasts all day except in the summertime. But when I do get oily looking, I can just put on a little more over my makeup and it looks like I just put on my makeup. I just wish it was available in stores. I hate waiting for things I have ordered. It seems a little pricey for such a small tube, but a tube lasts me for about 6 months. At 15$ a tube, it's 30$ a year for non-greasy skin. Well worth it in my opinion.

This absolutely sucketh.
I love MK products normally, and this made my oily skin look like an oil slick.
I have tried it so many different times - in different climates, using different foundations, face creams under it, different powders on top it. .

No. Very bad. Do not recommend for oily skinned folk.

I am in love with this product. I have very oily skin, especially in my t-zone. I have tried all kinds of mattifiers (Dermalogica, Clinique, Boots, etc.) and this one is absolutely the best. I literally get oily and shiny 20-30 mins after I wash my face with no mattifier. This keeps me matte for hours. Best primer for oily skin ever, it evens out skin texture too. I like that there's no fancy packaging so you can get to every last bit of this, especially since mattifiers are expensive per ounce (though not as expensive as other brands). Cut open the top when you can't squeeze any more out and get every last bit, this stuff is worth it's weight in gold. I will NEVER be without this in my makeup bag. It's so hard to find a product that works for oily skin. Love love love it.

The best thing i've ever used to stop oilyness, I barely ever get oily on my t-zone when I use this, I just have to do a small touch up with an oil absorbing sheet or powder if it does get bad. The only problem is it's hard to get out of the tube.
