A foundation stick that doubles as a concealer, an eye pencil that works as eye shadow and brow pencil and a lip crayon that can be used as a blush. Simple, quick and it doesn't take up too much room in my handbag. Revlon Photo Ready Insta-Fix make-up is brilliant. It has great, light coverage that's layerable, non drying and it doesn't sink into fine lines which means it works well as a concealer. I'll often use this as a touch up in the middle of the day.
The eye pencil I've been using is the ArtDeco Mineral Eye Styler 62. It's a mid toned taupe which makes it really versatile. It's dark enough for my brows, looks good when it's sheered out as an eye shadow and is a lovely eye liner. 
I'm in love with the new Models Prefer Moisture Lust Lip Tints. I have the Shine version and the Matte version and they're both great. I have the Shine in Watermelon Refresh in my make-up bag, despite what you'd think from the name it's a medium mauve color. On my lips it's a natural, mlbb shade and on my cheeks it gives a very natural flush.
The other product I always have in my make-up bag is a multi purpose salve. At the moment I'm using the Dr Lewinn's Multi Moisture Balm. I like multi purpose salves as they can be used for so many different purposes, the Dr Lewinn's one can even be used as a primer or moisturiser. I like to dab a bit under my eyes if my concealer is looking creased in the middle of the day, it gives a boost of hydration and the lines are less visible. What products are in your make-up bag?
