Tinted Moisturizer: This spreads on easier and quicker and all you need are your hands. Foundation will require tools and snatch some useful time due to blending and getting the right finish. Put some Tinted moisturizer on your hands and apply on your face. If you have spots that you feel is important to cover, grab your concealer, cover up the areas that is need and you're done with your base.
Blush: Apply blush to the apple of your cheeks with your ring finger. Do this until you've achieved the desired intensity.
Pencil: Take a soft Black or Dark Brown eye pencil and apply to your lower lash-line and blend with your finger. Gently pull out the outer corner of your eyelid. draw a line and connect it to your lower lash-line. Smudge this for a nice and defined round or winged effect. (remember to clean your hands so your don't stain your base) DON'T FORGET YOUR EYEBROWS :-)
Mascara: Apply your first coat of black mascara on your eye, move to the next, while the other dries up. Then come back for a second coat. This gives a fuller effect.
Lips: Since your eyes will look pretty simply. I advise your go for a lips colour that is a tad deeper in shade. If you prefer your lips to be pretty nude, go for just one to two shades deeper than normal. But if you don't mind a Red, Pink, Purple lips colour and if it is appropriate for your kind of work. Then, I say go for it. This will make your overall look pop. Dust your face with your blot / sheer powder and TADA... You're done, baby!
Have a good day at work!
