I must say that 30$ for a primer is a little too steep. I splurge more than that on foundation, but not a primer. But i bought a set of trial size primers at sephora for 9$ and must say that it's very likely that I will buy a full size. In fact, this is my first sillicon free primer and i love it more than sillicon based. It gives the same smooth feeling to the skin than sillicon primers do, but lighter. Besides that it keepsy make up on its place for long enough there is another big reason I like it that is illuminating effect which is very subtle but noticable. But it's not only this, there are plenty of illuminating products on the market. I was pleasantly surprised to notice glow through the foundation which I applied on top of primer. In my not very long experience I couldn't Find such product.
I am a fan of glowing skin, but I couldn't reach that glow with my let their be light (E.Ardan and Estée Lauder illuminating serum. As soon as i apply foundation on top of them the illuminating effect is lost. My skin is not flawless to use any illuminating serum or primer on its own, in most cases I need to use medium coverage, sometimes I can do with tinted moisturizer, but only sometimes.
I am keeping my fingers crossed that I will continue noticing the glow through other foundations too. But as far as my .25 oz almost gone I am more than satisfied.
My 4 lippi rating is only because of the price, otherwise 5.

- update. I'm over my . 25 squize bottle but still can't see myself buying it for $30.I agree with some of the reviews that it's not worth it. It's a good prime, but after shopping around at Walgreens I came across Loreal illuminating primer which Is not more than $10. I better save this money and buy a good foundation when I run out of mine.

I've never actually used this as a primer under foundation. I only wear foundation very rarely. I bought this because I'm a busy new mom and it adds a beautiful glow and evenness to my skin. When I am rushing trying to get out the door, I can slather a bit of this on over my foundation and look just a bit more alive and "done." If I use this, an eyelash curler, mascara, under eye concealer, and lipstick it's a pretty darn good day. The only reason I'm not giving this a "5" is that I don't truly know how it performs under foundation, and while I like the scent (maybe slightly citrusy?), in general, I think it is better if cosmetics aren't scented. I would definitely repurchase this to use it as I have been.

To be honest I don't know why this product is getting 5 star reviews. Don't get me wrong I love most all Tarte products but I'd say this isn't the absolute best primer out there especially for 30 dollars. It feels very nice on the skin, is made without parabens and other things and like always with their packaging - I'd buy it for that reason alone! Anyways, I've used this several times to test it with different foundations etc. and the one thing that this does no matter what is this: after a few minutes of it being on the skin moisture starts to bead up on top. I've used a tissue to absorb this and then applied foundation and there is still moisture there, in fact my brush was wet afterwards. This continues to happen throughout the day. I do wear only water based foundations with this as well. I think for me there are definitely other primers out there that work better and do their job.

Tarte's Clean Slate Flawless Primer is a "waterproof 12 hour primer" that "helps makeup stay in place longer while brightening skin for a healthy, glowing complexion." Like all Tarte products, this face primer is formulated without parabens, mineral oil, phthalates, sodium lauryl sulfate, and synthetic fragrances. I appreciate Tarte's relatively natural ingredients and simply product claims. This is one of my first products from the brand, I've been wanting to try their stuff for a while, I hear almost unanimously positive reviews of their products. I got a little 7.5ml (.25 fl oz) tube in Tarte's Clean Slate Primer Trio, which I bought at Ulta for $9. The full size of this primer contains 1fl oz (30ml) and retails for a pretty pricey $30. Tarte products can be bought from the brand's website, Ulta, and Sephora. Tarte is a cruelty free brand. This primer was made in Canada.
Tarte's Clean Slate Flawless Primer has very nice packaging, even the sample version! The squeeze tube is brown with white, silver, and spring green leaves encircling the top and bottom of the tube. The name of the product is written on the front in silver lettering, with "Flawless" written on the side in spring green. The tube doesn't have any pertinent information on it, the larger tube may offer more. Twisting off the black plastic cap (full size's cap is lacquered wood, I think) reveals a small hole for dispensing product. This primer's tube is a little bit on the stiffer side, so it's very easy to control how much product you squeeze out.
Tarte's Clean Slate Flawless Primer is a light white liquid with a soft pink pearlescence to it. The texture isn't at all like I expected, it doesn't feel like any other primer I've tried. Flawless feels like, and kinda performs like, a very light moisturizer! I use this primer all over the face, applying it with my fingers and lightly patting it into the skin. Tarte's Flawless primer sinks in quickly, so you're ready for foundation right away. The effect of this primer is very subtle. I didn't notice anything the first few times I used this generously sized sample. Flawless gives a soft, dewy, illuminated look to the skin, it's a very pretty effect, but so subtle that I don't think it's noticeable to anyone but myself. The effect would likely be much more profound on those with drier or duller skin. As for elongating the wear of my foundation? I don't think Tarte's Clean Slate Flawless Primer makes much of a difference. This just isn't that kind of face primer, regardless of what Tarte claims. I will say that it doesn't negatively impact my foundation wear. Flawless has a soft, fresh, mandarin orange scent to it that doesn't seem to transfer to the face.
I think the overall effect you get from Tarte's Clean Slate Flawless Primer will vary vastly based on your skin type. I mean that's true for any product, but even more so for this one. If you have oily skin or a very dewy, youthful complexion you definitely don't need this product. If your skin needs that extra little punch of moisture of your want and an extremely subtle luminosity you'll adore Tarte's Flawless primer. I wouldn't repurchase this product, it simply isn't something that I need. I also prefer Benefit's That Gal when it comes to brightening primers. I don't think Tarte's take on brightening primer is bad though, I'm glad I tried it out and I'll continue to use what I have left. My favorite part is the nommy orangey scent - and I hate oranges!

water based, waterproof primer with no silicones and other things (it said it on the box but i forgot what it is formulated without and i dont want to give false information)
this stuff is so good. no smell, white cream, in a plastic squeeze tube.
does what it is meant to, it holds my foundation so well. i dont think it does much in the wa of oil control but i use UD De-slick spray to control oil so my judgement on that isnt too great.
the cream isnt thick and it is easy to spread. you only need a little amount for your face too. no shimmer or glitter in the cream too which i like and actually just feels like youve put moisturiser on your face. theres no smooth babys bottom sh*t going on. doesnt feel like a slippery wet plastic (MAC Prep + Prime feels like a slippery wet plastic layer ew)
it was $30 at sephora which i will pay again for this product. as fort he brightening part, it is meant to be like a treatment primer that has ingredients to improve your skin as you wear it, not like Benefits that gal brightening primer, that is meant to make you look brighter temporarily. i havent really noticed any brightening going on but regardless, i love this primer

Well, I have found my Holy Grail Primer.
This was no easy task let me tell you.
It seems like I have tried EVERYTHING. Drugstore, high-end, natural, setting sprays, etc. I was using ELF Mist and Set for a good while, just out of giving up on the whole primer scene. then, I started using an all natural Aloe Mist, which was great, and I still use it on my lazy days. But when I want my skin to look and feel flawless, no matter what is going on underneath the makeup, this is it! I am so glad Tarte made their mini Clean Slate trio, other wise I would have never tried it. Its a bit on the expensive side, you try the mini sampler first before you invest. But I think its so so worth it.

It goes on smoothly and settles into the skin quickly.
It evens out texture and doesn't sit harshly into fine lines.
Its a silicone base, but its NOT heavy or thick.
It allows the skin to breath but locks the makeup on.
Its doesn't pill up when you apply makeup on top.
I hasn't broken me out once over the 3 months I have been using it so far.
I use less product all around when i use it. (primer, foundation, concealer powder)
It gives a nice "glow" but has no shimmer or glitter...Its almost like what mineral veil does for you by giving you that "soft-focus" look without any shine. I cant explain it almost. Its not like strobe cream by MAC. Its far superior to that.
It keeps my oily-ness at bay far longer than any other primer.

I cant gush enough. Im in love!

I bought this during the 30% off FF sale which took some of the sting out of the pretty steep $30 price tag. I haven't tried any of their other primers so I can't compare this to anything else from their primer line but I do like the ingredients and love what they haven't put in, mainly the lack of silicone and glitter. This illuminates without any sparkle and Tarte's obsession with everything that glitters is my biggest turn off with that brand so it was a nice surprise. This reminds me more of Smashbox Illuminating Serum the one that used to come in a tube with the Masters kits before they ruined it and reformulated with silicone to break me out and make my face look like someone wrapped it in saran wrap by noon. It isn't as pink though and has a light lotion texture that goes on smooth, blurs small imperfections and works well as a light primer under or mixed with makeup. This contains Retinol as well as vitamins C and E so it helps keep skin smooth and clear and works well as a light moisturizer in the summer but since it has no spf I'd use it with something that does. I have Combo skin and this doesn't make me oily or look shiny and I like that there's silica in the ingredients instead of kaoilin to keep skin balanced. Kaolin is too drying for me and actually makes my skin crank out even more oil. I've yet to test this outside for any length of time in high humidity for staying power but if they made this in a tinted version I'd wear this as a tinted moisturizer for days I wanted to keep it light. Tarte products are always a hit or a miss by a mile with me but this one is a keeper although I'd still cringe at coughing up $30 for it unless they came out with a tinted version and this truly became a multi- purpose item for me. I can see this tube going pretty quickly and I may have to wait for a repurchase until another sale comes along.
