All time favorite beauty MUST-HAVE!!

Hello, hello on this beautiful day :)

How is everybody feeling today? I hope you all are having a good day with lots of happy moments :)
Sooo, today i want to talk about my all time favorite BEAUTY-MUST-HAVE make-up item :)
My mascara! I often ask myself the question what make-up item i would keep if i could only own a single one (and trust me, i have quite a lot, more than i probably need, but of well we all have our little weaknesses ;)) ; and i really have to say that mascara is the one thing i wouldn't want to miss out on.
Not only does it maintain a natural look but it also accentuates the most beautiful feature of the face, the eyes. I personally have blonde eyelashes so without dark mascara i often look tired and not as awake, so my mascara can change my whole appearance in just a few seconds :)
It simply is a great invention! :D
The mascara I am using right now is the L'Oréal Million Lashes Luminizer for blue eyes, and I am very happy with it :) I have to admit that using it on its own, I can not really see the luminizing effect it is supposed to have (it stands out great with blue eyeshadow though), but it gives my eyes a little softer look than black mascara would.

I am very curious to know :)

Have a wonderful day,
