She's not even allowed to make sweeping claims like that. Ordinary cosmetic assessment doesn't allow for it. It must be classed as medicine because 'healing psoriasis' or whatever is not a COSMETIC function. Cosmetic functions are things like making your hair soft, moisturising your skin, making you smell nice. So she can say her creams are moisturising, but she cannot claim they treat or even cure specific medical conditions.
The only way she would be allowed to do that is if they are actually classed as medicine, and that's a whole new kettle of fish. I somehow doubt she's gone this route else she would be labelling them as medicine, with all the trappings (and cash) that comes with that. But, quite simply, shea butter with a few additives WILL moisturise you, but it WON'T cure anything like psoriasis, so she would never get certified in this manner.
I'm giving her information for free right here, since we all know she's reading. Feel free to send me the cash for doing your work for you ZB- though, you should know all this already, right?
There's no way that tiny bit of titty psoriasis had her quitting school, so where was it? If people who knew her had no idea then she wasn't 'head to toe' in it, and there seems to be no evidence for that claim. Just like her other claims, really: see above
And while I'm here, might as moan more, I wish she'd stop using her daughter to advertise her products. The wee one doesn't look very happy in some of the photos she posts. Maybe she'd rather her mum actually play with and spend time with her, rather than trying to monotise every move she makes?
