So many answers for you!

1) I frequently use my beauty blender dry. It really depends on which sponge consistency is best for you.
2) So I wrote this foundation post 4 years ago when I was just 36, and I think the concealer post you’re talking about is this one, my concealer over 40 post. I didn’t mention foundation at all in there, and I should probably write a post about how I put it all together. I’ve been doing eye cream, corrector, then foundation (and I avoid the undereye area as it’s yet another layer) and then concealer and light powder last. I hope that makes sense.
3) You mention that you’re currently using Tarte products. I have to say, I’ve found their concealers (in particular Shape Tape) are too thick and definitely settle into my undereye area very easily. I have an entire post on best concealers over 40, but my favorite is the NARS Radiant Creamy Concealer, which is just a little bit less pigmented than the Tarte but also easier to blend and I think less likely to crease. My Tarte sits in the drawer and doesn’t get used because of that.
4) I should write a whole post about lighterweight foundation options as you get older. I AM HAVING THIS SAME ISSUE. I am definitely going for more liquid foundations, and it is helping with the settling a lot. My favorites to help with this are the Lancome Miracle Cushion, the drugstore dupe from Maybelline, and today for the first time I’m using this one from Chanel, and OMG I’m dying. It’s amazing. I also bought the new “lightweight” skin finish one from Bobbi Brown. It has settled beyond anything I’ve ever used, do not waste your money!

I hope all of that helps and makes sense? Let me know and I will write some posts addressing these issues, my friends and I have been talking about this a lot and sharing tips with each other.

Quick newbie question, does the beauty blender need to be wet? Also it was very difficult to put this routine together and incorporate your concealer post. The concealer post mentions adding specific layers to under eyes prior to application. But I had already applied foundation in the order you mentioned above? I’m 45, using Tarte products, and lately everything settles. I end up with creases under my eyes. Makeup settling into pores despite primers. And setting sorry, don’t even get me started. It seems to make me glow in the dark ! Well, more like super shiny. Augh. It’s gotten so bad I’m considering not using foundation anymore, despite years of taking care of my skin. Thanks for listening ladies.

When I took these pics I used only natural light, though it was slightly overcast and I had to correct a little to remove a green tinge from the pics. On my monitor (which is super calibrated a'la graphics artists), it was about a 95% match, I could barely see a problem (though yes, my neck is super light, I've been told by MUAs like Jake Bailey to leave it alone though, just match between my neck and my face). So, I debated but didn't have time to retake pics so I posted this anyways.

But, on some people's computers, especially if you just left the monitor calibrations as they were when you bought it, I guess it looks orange. I don't know, I haven't seen it!

In person the foundation match looks good. In pics on my computer it's about the best I can do, almost no issues. I do have to say though, there have been threads about my foundation match on places like Makeup Alley and the personal attacks are a bit… crazy? What's wrong with people? First, it's a stranger's foundation match. There are more important things in life. Second, it does depend on your monitor from what I've been able to tell, maybe something's a bit up on your end? Third, really, just calm down and move on??? Sigh.
