I haven’t used these extensively, and less so in the last year or so. I think the only noticeable area that could benefit from it on me is my redder cheeks, but liquid foundation is usually enough for me, so the extra step of color correcting doesn’t appeal to me as much. I’m glad they exist, as they are useful for some!
For the face, I think sponge applicators are still really useful, especially if they’re more durable so you can get more than a few uses out of them. Ones for the eyes I find less useful in a day-to-day routine, since they are harder to use (too large for me/the sponge often pulls away from the plastic holder) to really get a nuanced eye look.
