Question Smudge Technique?

I'm aware I dont come here often, but can any of you kind gents inform me on how to accomplish smudging as shown below. Im not even sure if it is or not, but if it looks farmiliar to any of you, hit me up. :\

 

Oh it looks familiar lol. It looks more like liquify to me.

 

That certainly is liquefy, but it looks like there's another filter on the undertone there... it might be high pass, but I am actually not 110% sure. :(
