Skincare: Then vs. Now

The amount of effort being put into my current skincare regimen (as well as makeup) has exponentially increased in the last month. Benefits include: 

-reduced undereye circles
-diminished pore size
-no more tight/itchy/dry feeling to my skin
-my skin is so effing soft!

And, maybe I'm deluding myself, but I swear there is almost a glowing effect. So, the question begs: what has changed?
