The colour match is fantastic, easy application for light or full coverage. I actually like the way it smells too. But, and its a big but, IT BREAKS ME OUT!! It makes my face itch and then causes cystic acne on my chin.
Its a shame, if it doesn't break you out then your lucky.

I absolutely love Studio tech. It's my favorite foundation. I haven't bought it in a while because on a budget and it's easy to use up pretty quickly. Also trying to use up all the other foundations I have.

I am about an NC37 but then again, the colour isn't a perfect match. I first bought it when a Christian Dior compact foundation (can't remember the name but it was hands down THE best foundation I have ever used) was discontinued, thinking the mac product would be a good dupe. Boy was I wrong. The mac product was good to begin with, but as soon as it started to dry (which happened quite quickly), it became difficult to apply. But the reason I really disliked it was that it made my skin break out horrendously. So for short term applications, it did the job. For long term use, it was certainly not compatible with my skin type.
A few years ago I repurchased this product. I wanted to figure out if the dislike that I had gathered for the product over a decade ago was just my imagination or not. Again, the second time around, the foundation disappointed me for the same reasons. Made my skin look horrible.

I bought this foundation in the shade NC 15 and have found that it's too dark and a bit orange for my skin tone which is the problem I always have with MAC foundations. Their lightest shade is never light enough for me in their liquid and creme foundations. Now with that said, I still think this product is pretty good. I found it provides a light to medium buildable coverage and would probably look good if they had my shade. The only problem I have with this product is the fact that you have to pull at the skin to apply it. I try to avoid doing that at all times especially around the eye area.
Anyway, I personally would never buy this product again for two reasons: they didn't have a shade suitable for my skin tone and I don't like pulling at my skin when applying anything.

Okay
so this foundation is PERFECT for a REALLLLLLLLY full coverage seeking gals, but this is too heavy for me.
Pros
- Full Coverage
- Long Lasting (without powder or primer)
- Smooth Formula
Cons
- I wasn't matched to the right color
- Oxidizes a bit (orangey)
- Made me break out (nothing breaks me out)
MAC counter people SUCK at matching sometimes, so please ask more then one person.
* Use a wet beauty blender*
* Wet Brushes*
* Primer for best results*

I really like this foundation. The SA helped me find the right shade for my slightly-tanned self, which was NW15. The holes in the compartment holding the sponge are great and the sponge is very handy and the mirror and container are great.
The coverage is medium-full, which I love
The feel on the skin isn't very heavy, but you can feel it slightly with wear
The lasting power with powder is intense, which I love
The color selection is good
Overall, I like this creme foundation, but I wouldn't call it an HG due to the feel of it and the selling out for animal testing which just plain bothers me.

I love this foundation. I have normal/dry skin and stipple this on with the sponge provided. Only downfall is after a few hours it can sit in fine lines. I do prefer my ELDW than this but this is another good full coverage foundation that comes in lovely shades.

Before I begin, I have suffered from cystic acne for about two years, my skin cleared up a little about a month ago but I still have a lot of scarring and I do have the occasional pimple here and and there. This guy on youtube said that creme foundations are the best for acne scarring because of they are significantly thicker in texture and will more often than not cover far better than any liquid foundation.
I was using Illamasqua Rich Liquid foundation in 200 (a little light for me), it is full coverage, absolutely no doubt about that, however it was sort of heavy so i would mix it with my moisturizer to make it more applicable, I was happy with it for about two weeks until I started to notice that despite the moisturizer my skin was getting drier and drier so I stopped and headed out to MAC to get the Studio Tech Foundation, and thus far I am VERY happy with it, the color is dead on (NC30) I know it says it's medium coverage, but I find it to gives me a full coverage. I apply it with my beauty blender and I just bounce it all over my face and a little bit down my neck, and let me tell you something, my skin looks very nice and not dry at all, I just spray a little bit of Fix Plus after setting it with my Mineralize Skin Finish to tone done the powdery look, and I'm set for the entire day.
I would highly recommend this product for those of you dealing with acne or acne scarring. This foundation works wonders!

I'm still on the fence on this one. I'm not sure if my skin just looks good these days (since I've been using natural products and a good moisturizer) or if its this foundation. I like the consistency, very dewy and thick. I bet I could really get a full coverage with this one, which I like. I'm NC43 and this matched my skin tone PERFECTLY. So much that I have to really be careful not to over apply since I don't know where I applied and when I didn't. This foundation lasts all day and it doesn't get all cake. However, I feel like it kinda gets itchy throughout the day. Just a little bit. But it does stay put. I just don't like the feeling of foundation caked between my fingernails when I'm scratching my cheek. I'm really glad I found this because no more gray and dry looking skin. This makes my skin look flawless. I pair this with my Modern Mandarin blush and I look H.O.T!

Very good for certain things (TV for example) but again very very dry!

I really like this product for special events/pictures. It's a heavy cream, however it can be sheered out with moisturizer and can double as a concealer. Skin is perfection with it on, almost unnaturally so in person, but heavenly in pictures. As with all cream foundations, you need to set it well with a translucent powder. Doesn't cause me to break out or my eczema to flare up. One of my favorite MAC products.
Shade: NC45

This is the only foundation I've ever repurchased and I've hit pan on my second one. Meaningless to most but I've never done that before!! I love everything about this.
I apply it the way sharonmakeupartist and pixiwoo have taught me, spritz face and buff in. And it looks amazing, covers my pores and lasts!! I will be repurchasing again, although I might have to go a shade lighter. I swear their colours are running darker, my NW20 is too dark for my skin when it wasn't with my previous pan.

I am also very surprised at the super low ratings this product is getting here. I have a love-hate relationship with cream foundations. It is actually the form of foundation that I prefer, but it is very hard to find someone who does it right. I think that this is one formula that MAC really does succeed with. I am NC44 and when I use Studio Tech, I find the color is perfect for me. I can't say the same when I've tried/used NC44 in other MAC foundations. The only complaint I have about this foundation is that it tends to transfer easily. If MAC could find a way to make it more durable, this would be the only foundation I'd wear.

I used to use Covergirl Aquasmooth foundation, so I figured this would be a great cream-to-powder alternative to try a more high-end product. In all, I HATE this foundation. My color options were either too yellow or too pink based and it definitely felt cakey on my skin. I applied it with the MAC 130 brush which actually made it look nice and air brushed on my skin, but because I have oily skin it never seemed to feel "powdery" on my face but rather sticky most of the day and I had to constantly reapply setting powder throughout the day. The packaging is nice, I like the compact with mirror aspect, regardless of the unhiegenic sponge applicator it comes with. This would probably be a great foundation for someone with dry skin, but if you have very oily, acne prone skin like me, stay away.

PROS:
Perfect packaging...I hate liquid foundations!
My faces is not "heavy".
I have rosacea: it covers a lot without using a concealer or a finish powder!!!
I bought a darker shade (for flawless summer nights) and it's not so bad!!!
CONS:
The price (and I'm not really sure that worths 34€!)
It transfers everywhere (sunglasses, telephone...)
No, I won't buy it again because I would like to try other MAC foundations!

worst foundation ive tried :/ i could not for the life of me find a good way to apply this, tried everything! wet sponge, dry sponge, paddle brush, stippling brush, flat top kabuki , it all looked bad :( extenuated dryness , melted off my face in oily spots, about a half hour after application, thats with using blot powder as a setting powder. good coverage but looked very cakey no matter how applied

I was told by my make-up artist that cream foundations would last longer than liquid ones so I went ahead and picked something from MAC that is cream. And the first one that I saw was Studio Tech. I love the packaging, and the way it goes on creamy and dries to a matte finish. It covers most of my blemishes and I don't apply concealer anymore when I use it. The only con is that, during the day, my face would itch a bit especially around the cheek area (since I am combination skin, my cheeks are dry). I got tiny bumps on my cheeks after I took the make-up off.

I bought this, and returned it before I even used it. When I looked at the ingredients it contains a form of FORMALDEHYDE! That's what they put in dead bodies people! It also contained a quite large amount of wax, which clogs pores. A friend with eczema told me she used to use this and her dermatologist told her to quit as soon as she told him what she was using. He said MAC is the WORST makeup to put on your face. It's so bad for your skin. If you at all value the quality and health of your skin, I say you skip this stuff. Leave it for the theater majors & drag queens. continued >>

My skin is super sensitive and oily so I have to be very careful when trying new face make-up. I don't use this as my actual foundation (I prefer Revlon surprisingly) but I use the studio tech NW40 to contour my face. After applying regular foundation, and what I use as highlighter in certain areas, I put some of the NW40 on the sides of my nose to make it appear slimmer and along my jawline to make it more defined. I LOVE it. You have to be really careful when contouring because it can look like you didn't blend your colors well, but I find this looks natural in person, and works in photographs, too!

I have used this product for awhile however, will not repurchase. The color is too light and the next color up is too dark. It is a cream that also sits in my pores. It doesn't look natural.
