If you have dry skin, try Neal's Yard rose facial oil as a moisturiser morning and night. smell lovely, little bottle lasts forever and will give dry skin a lovely sheen.
if you have good skin, avoid foundation or heavy powders - you don't need them. Just a light powder to dust over nose and face to take down any shinyness.
Touche Eclat very good for bags under eyes and the odd spot. Expensive but again last forever.
Pale matt eyeshadow on eyes, swept over the whole socket, will 'open up' the eye area. Don't put it on too heavily though as it can settle in wrinkles (not that you have any I'm sure)
I swear by this Clinique blusher (fresh bloom). Invest in a good blusher brush - nice and fat. Swirl over entire palette and then brush onto the apple of your cheek in circular motions. Repeat with other cheek and then brush down nose and across forehead to get rid of any left on the brush (don't dip in the blusher again as will be a bit OTT on nose/forehead!). This makes me look healthy even when I've not slept for months - always get 'you look fantastic!' comments when I wear it. Expensive but lasts (there's a theme developing here).
Vaseline or gloss for lips - if you're not used to make-up, lippy is a nightmare to get right and takes a while to apply. I can never be arsed.
Good quality mascara.
If you want to go for the wow factor, a tiny bit of facial fake tan along with your usual moisturiser in the morning - by the time you get out you'll have a lovely glow.
takes 5-10 mins all in once you get hang of it
