So, to preface: I have combination dehydrated skin with some texture issues. Large pores on my nose, persistent flaking there as well (possibly seborrheic dermatitis or something) and sometimes hormonal acne, although that's almost completely under control now. Texture, I have it.
I also have a very hard time getting foundation, any and all foundation, to stick to my nose. Literally. It does not stick, or it will separate, pool in my pores, show up all the flaky bits I didn't even know I had and look generally awful. It's like trying to blend two things that just will not mix, you know? Like trying to blend water on a hydrophobic surface. I've tried applying with brushes, with a beauty blender, with my hands, different techniques. I've tried a fair number of different foundations, silicone-based, water-based, powders and even an old-school oil-based one or two. I've tried different primers, pore-filling ones, hydrating ones, mattifying ones, and so on. Spraying some Fix + on before does help, as does making sure my face is well exfoliated, intensely moisturized and hydrated beforehand, but it's never, ever foolproof. The rest of my face looks fine, but my nose is sometimes such a disaster area with foundation that I've turned more and more to sheer, natural-looking foundations, because they tend to look the least awful. MAC Face & Body generally does ok, as does the Pixi H2O SkinTint. Mineral powder foundations are a bit hit and miss. Estée Lauder Double Wear, not so much; it shows up every bit of texture and, weirdly for a foundation with such industrial-strength lasting power, doesn't really adhere well either. Double Wear Light does slightly better, but it's still tricky. The Bobbi Brown foundation stick is a disaster, most concealers don't want to play nicely either.
And so I got this primer, because I've been on a bit of a Deciem kick lately, a few of their products have worked extremely well for me and there were those magic words in the name of it; High Adherence. Yes please, I would like some high adherence stuff to put on my nose, thank you. I don't even care if it makes foundations last longer, I just want something that makes them actually stick and blend nicely on my nose to begin with.
And lo and behold, this works. This actually does make foundations adhere better to my nose and not separate immediately. They still pool in my pores if I'm not careful, I'm going to try this out with a few different pore-fillers underneath and on top. I still have to be ever so careful applying. But it does what it says - helps foundations adhere to the skin - and that's what I'm here for.
