Wrinkly fingies?

I, 29F, 5’5”, 175lbs, non-smoker, non-drinker, have been dealing with wrinkly fingertips for about two weeks now. They look pruny, which is fine, but it seems like the skin is peeling in some spots and it’s getting pretty tender. I’m hydrated, I take Claritin, and I don’t have any diagnosed conditions other than being overweight. I don’t have any fingertip based hobbies like guitar. I haven’t started using any new skin products. The rest of my skin seems fine. Honestly have no idea what this is. Photos in comments.
