Thick eyeliner is out.
But not for night time looks or smokey eyes.
Keep the eyeliner minimal throughout the day and if you have been wearing eyeliner religiously like I have and cannot quit the habit, line lightly.
What I've been loving lately is using a cream eyeliner and an eyeliner brush with thin slanted edges (the one from ecotools is ideal) and lining the outer porting of my eye lightly, but when coming to the center and inner conner using the thin edges very slightly.
This will allow your eyes to look more open and bright...
Much Love <3 M
