I am browsing in my local primark, got some nice shirts for my boys (which they will reject in favour of lurid soccer tops, but however)
So I'm mooching round the toiletries, and see a new item that interested me- makeup setting spray. 'Oooh' thought I. 'Might be worth a look'
Ingredients- top of list, denatured alcohol, propellants and that's it. 
Can you imagine the damage that would do to sensitive acne probe teenage skin? Next item on shelf is the makeup brush cleanser. Same ingredients but at least there is some glycerin added!!!
