For me it is when companies/services market themselves as donating to XYZ cause if I buy their product. If they want to donate, they should have already done that with the money they have. Asking me to give them profit so that they can donate is so obviously pretentious.
There’s this ad I keep seeing that I really despise. It’s for teeth-whitening toothpaste. The actress is wearing a white coat then holds up a tissue to her teeth, lamenting that her sparkling white teeth are ‘still yellow’
They cut away to teach you how toothpaste works, because surely you’ve never heard of this newfangled thing, and when they cut back she’s no longer wearing her white coat and says how much whiter her teeth are.
It’s transparently obvious that the wardrobe and tissue are just to give you something whiter to look at. But like… your teeth aren’t supposed to be freakishly white. It’s just something that Big Toothpaste wants you to feel bad about the way your body is. Also, using whitening toothpaste when you don’t need it can damage your enamel and cause you long term problems.
PSA whitening toothpastes are just normal toothpastes with added abrasives. So they temporary whiten your teeth because you’ve removed the outer most enamel which gives your teeth its hardness. At the mere cost of tooth sensitivity and future staining, the deeper dentine layer is much softer and porous which is easily damaged by acidic foods but also more easily stained due to the porosity. So congratulations your teeth are now more stained.
Unite against big toothpaste! I agree with those.
