how about pressed and liquid mmu do you have any idea?
i believe there are bactria growing when u got some organic stuff in your makeup like u dropped something in your powder but as soon as its consmed the bacteria will die and wont grow again til there is food for them~ but of coz that might happen often with duct dropping into your foundation however i think thats very minimal
I read that as long as there's no rice, corn powder or anything that can feed the bacteria, then it doesn't have an expiration date. So as long as they are all chemical minerals, I guess it should be fine.
