I've always loved hydrating facial mists, and the Rituel de Fille Thorn Milk has become a staple in my collection. Aside from just looking cool (it has a bi-phase liquid that needs to be shaken up to be mixed), it instantly soothes and calms your skin as soon as you spritz it on. Any dry patches or light irrititation I have is instantly smoothed over, and it plays so well under makeup!
All of my foundations have layered on top of it beautifully, and it keeps my skin hydrated throughout the day, so any dryness or makeup breakup I'd experience due to my skin getting drier throughout the day is gone. That says a lot, especially because we're in the middle of winter!
The other thing I've been using nonstop since I bought it is the Artis Mini Palm Brush. I am really picky when it comes to foundation application tools because the foundations I tend to like are the types that dry down super quickly, so they give you less time to blend and tend to look streaky if not used properly.
However, this Artis brush changes all of that! I was able to blend out the foundation on my entire face with less time spent blending and no need to apply more product to the brush - I was shocked that I could cover my entire face with less product than normal! I was even able to lightly tap the brush on areas I wanted fuller coverage (like over the sun spots on my cheeks), and it built up beautifully.
