Yes but hard to follow up. I usually just buy anything that I use up or like a lot.

Yes as it is always mentioned on the label of the product and I follow accordingly

Not really.. too many different items with different guidelines.. it's confusing..

But I keep them for longer anyways as I dont put full on make up often

Oh I’m actually not too sure... but I heard should change yearly

I nvr bothered until i had to develope rash. Yikes! 😬

We are supposed to follow the expiry dates

Based on the PAO or when it smells weird

I should replace mine more often 😬

Yes check the bottom of your makeup.
