My ex used to REEK of bad makeup. Ugh, it made any chance of getting in any closer an impossibility for me. Dollar Mart makeup not only smells bad, but I've heard it's actually bad for your skin. Can't confirm that, as I'm not a dermatologist or anything, but I've heard it through the grapevine.
Yeah cheap make up smell a lot
Can confirm this. I used to go to stage school, so was wearing heavy make up from the age of 6. We've never had much money, so I had to make do and, as a result, my skin is wrecked. Now I can afford my own cosmetics, I've definitely noticed the difference - from really cheap stuff, to middle of the road to higher quality.
Also, obvious things like not taking it off at night can affect skin. Of course.
