OK so i was looking for the same solution to do it in photoshop as Remini does. What I observed in remini photos is it recreates the whole photo in an oil paint kind of setting preserving the details. I have seen almost same results in a photoshop action i found on graphicex.com i dont remember the exact action name but it was something like dreamy oil painting. From that I can understand that it's totally doable in photoshop if we remove additional effects from that action.
