I have NW20 skin (Cameo 022 in Diorskin) with mild rosacea. When I'm not on birth control, or when my diet gets bad, my skin will flush and burn. Diorskin Nude gives me a beautiful, hydrated, glowing look with perfect coverage every time! It's completely buildable; I can put on a thin layer all over my skin, then add an extra layer to my cheeks as "insurance" if I flush/am having a bad skin day, and my face looks flawless! It really matches the relatively nice skin on my nose, chin, and forehead; it's MSBB (My Skin But Better!).
I own the Sephora Airbrush #56, which is lovely for applying any foundation. I do find that I get even better coverage when I use my fingers, but that may have more to do with my brush skills than anything else. I also have to say that the bottle is exquisite; it's heavy and well-designed, and the pump has given me no issues whatsoever. You honestly don't need very much product to cover your face; one to two pumps should be plenty, but of course you can build as necessary. So while Diorskin Nude is one of the more expensive foundations out there, a bottle should last you a very long time even with daily usage. And don't forget, you do get what you pay for! In this instance, you're getting a high quality product that won't clog your pores, irritate your skin, or make you look like a pumpkin!
Yes, the color does change ever so slightly after a few minutes, but it absolutely does not turn orange or yellow. It just seems to blend into your skin, and it matches my neck pretty much perfectly. I had previously been wearing Sephora's Hydrating and Smoothing Foundation, which was terrible; it oxidized at random times, and did nothing for my dry skin. When Diorskin Nude arrived at my house on a Friday afternoon, I washed my makeup off and re-did my entire face before I went out for drinks with a friend who had seen me earlier. Her first comment to me was, "Whoa, your skin is glowing! It looks SO smooth! What did you do differently tonight?" In the past few weeks, I have received multiple comments about how "flawless" "beautiful" "smooth" and "pretty" my face is. I am told by strangers and people who haven't seen me in a long time that I have "wonderful skin," and they're always amazed to learn I have rosacea; some of them don't even believe it! I now feel comfortable wearing just this foundation and minimal to no eye makeup to grad school classes/to run errands as needed. I feel when my skin looks perfect, I don't "need" much else on my face if I don't want to or don't have the time!
I highly recommend going to Sephora and getting a proper match, having an SA do your makeup, then go home/out and get reactions from people you trust. I do have to caution that sometimes an SA can get it wrong. As mentioned, I do wear Cameo, but initially my lovely SA matched me to Ivory. I came home and was asked by a family member if I was feeling okay; Ivory washed me out and made me too pale! Looking at more swatches online made me realize that Cameo is virtually the same color as Ivory, but with a touch more pink/color, so that's how I knew it was the right shade for me. So remember, getting swatched is often the first, if not only step to finding a match, but don't be afraid to take your time and explore other shade options! I do owe my Sephora SA a huge thank you; I originally came in wanting to try Lancome's Teint Miracle, but she showed me Diorskin first, and I never looked back! I also found out that Teint Miracle can smell like alcohol when it makes contact with your skin; I'm so grateful she steered me in the right direction (even if the Dior is more expensive).
