I'm so careful it's not funny.
I make sure it is a good brand like Max Factor or Revlon, they suit me.
Mascara has to also be a VERY good one, and I always smell them(tester) if they smell bad, I don't buy them.
Too many chemicals.
I really am trying to stay clear of too much eye make-up.
I tend not to be a very 'precious' person about things, I put it down to my character traits both good and bad of eg...impatience, efficiency, 'just get it done' attitude, frugality and practicality (laughing at myself here!), trying to think of some others....oh and low budget!! Paradoxically though I realize I am quite fussy with food, so I guess I am precious in this regard..
Well all make up will have chemicals in. It wouldn't be possible to make it without chemicals.....
I don't wear make up any more but when I did I used to buy really expensive stuff as I thought it was one of those areas where buying cheap would be a false economy. Not sure if it was organic but it was definitely made with quality ingredients.
I have not worn eyeshadow in months. Last time I did was just after Christmas last year - for a wedding. Mine probably have chemicals in them, but I would like to buy some more natural ones for when I do wear it though.
