Using Skype on PS Vita

I'm struggling to set up Skype on my PS Vita.

I had a search through Playstation Store but couldn't find the app in the Social section, where I thought it would be. A Google search suggested to input a direct link which I did but on the Vita, it didn't bring up a download button so stuck at this juncture.

Any tips on how to download it or alternatively, other ways to download Skype onto the Vita.

Thanks
