heee i was thinking about starting a thread like this myself! But I will just add to this one.
I have a tiny bag that I sort of rotate depending on whether Im actually wearing makeup etc.
Generally it is moisturecover nw15 for emergency pick-me-up like after work when I look tired but i need to go out directly after.
Zia sea tonic aloe toner comes in this 2oz spray bottle that is super convenient and just wakes my face up and moisturizes perfectly.
I generally follow that with blot powder in medium on my forehead
Scharffenberger Lip ganache is a stapleeee, and sometimes I carry l'occitane tinted shea butter balm in mûre sauvage for color, lips and cheeks.
The only thing I really wear every day is mascara, and I don't ever carry it around.
