Undereye area is really specific and for most of us - problematic! I think everything goes back to the good skincare routine, we need to prep the skin well before applying makeup. Remember about good undereye cream but also massage! the skin will be firmer and hydrated. In terms of the makeup - we need to start with a primer, to prevent creasing! And as someone who has naturally dark circles, I need a colour corrector - I use red under my eyes to cancel purple/green veins. Then a great concealer is a must have with a setting spray on top :) In terms of creasing - less is better :)
