What the gurus are saying

Over sunscreen, this primer flakes dramatically, white specks fly everywhere across multiple test attempts. The reviews split: catastrophic failure every time versus working beautifully with certain foundations. The product's label warns against skincare use, and these results confirm why, this primer is finicky about what layers with it. It smooths pores beautifully, though you will need to test your foundation combo first, or just follow the label.

"I hate the Peter Thomas Roth Instant FirmX No Filter Primer so much. This currently has [...] a 2.5 rating on the Ulta website. [...] The first time [...] I used it on top of my sunscreen it was a disaster, [...] it mixed with my sunscreen [...] and created this awful film that started flaking off. [...] I tried it again using only serum and moisturizer, [...] and once I applied [...] sunscreen on top [...] it happened again, little white specks [...] flying everywhere."

"I finally found a great primer to recommend to you guys it is the Peter Thomas Roth Instant FirmX No Filter Primer. I can use it under makeup I can use it over makeup it's very lightweight and comfortable to wear. I apply it to this side of my face today and I can see the difference just putting it on top of my foundation it really helps to mattify just the front of my cheek and make those pores not completely disappear but a little bit less noticeable because they're reflecting less light."

"It is just magical. It does have fairly specific usage instructions. It basically says not to use it with any skincare and I can't do that, there's no way that I'm giving up my skincare for any makeup. I would recommend watching my video on how I use it [...] because it really works and it can really work with skincare with sunscreen. [...] In the video literally I put it on and you can see my pores disappear. It's not a filter, it's not blurring anything, it's this product. It works so well."
PTR Instant FirmX Primer ~ Holy Grail or Hot Mess?
"I love this primer. It magically made my pores disappear, which is what I've been looking for in a primer for ten years. My pores are completely minimized, some of my wrinkles are minimized, and some of that texture is minimized as well. I'm not really seeing anything that I would consider to be crusty or chunky, even putting it on top of all my skincare and a sunscreen that's very luminous."

"I found an awesome one just about a month and a half ago and I absolutely love it. It's different from the under eye product, it's a lot more lightweight, it's very fluid, it's easy to apply. [...] This is [...] a little finicky and it does take a lot of steps of letting it dry, [...] you do have to let it set for five to seven minutes, but if you have enlarged pores and you want your skin to look like velvet instead of an orange peel or a golf ball, this is a product for you."

"I did a video on this showing how I use it with my skincare, with my sunscreen, how I get it to work, and for me it's a fantastic product. [...] I can't guarantee that it's going to work for everyone, but I love this for using every day. I put on my sunscreen and it's really super shiny and all my pores are accentuated, and I just put a little bit of this on right on the fronts of my cheeks and [...] it just makes my skin look like velvet. I just love it so much."

"My before picture I'm pretty shiny because I have on my sunscreen, and my sunscreen always leaves me shiny, and shine always accentuates my pores. I love it that I'll be able to use it just over my sunscreen. I've been looking for something like this for years. My skin just looks like velvet, like super perfected, pores are gone, wrinkles are diminished, eye bags are diminished. I mean, it is so good."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Vitamin C

Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.

Sunscreen filters

Sun protection is the best evidenced way to slow visible ageing, and the filters are what does the work. Mineral and chemical filters both protect when a product is applied thickly enough and often enough, which is where most people fall short rather than on the choice of filter.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
