New To Mally - Poreless Skin Finisher vs Poreless Face Defender ??

Hi, I'm a big makeup junkie and love to try new things. I'm overstocked on LG, Smashbox, among others, however, I still decided to try Mally. The Share the Love TSV AD was my first Mally purchase. I liked it but still on the fence with Kit #2 so I delayed the shipment for now.

My question is, for those that have tried both - what is the difference between the Poreless Perfection Skin Finisher (in Share the Love) vs the Poreless Face Defender? I have so much makeup that I was thinking instead of buying Kit 2 with another PPSK (that I haven't even made a dent in yet), that I would try the PFD as an individual purchase since it seems more portable too. TIA for any help.
