I can't imagine how it would be possible for anyone to make money from Younique. I had not heard of them but I see on their website you can buy products direct from them with no middle person.
They are also very expensive. Their products are pricier than expensive brands like Clinique or Clarins and wildly expensive compared to Boots, Rimmel or any supermarket brand.
It's obviously a complete rip off but to be honest, given there are multipleways of buying existing, reputable brands at prices to suit all pockets, it is rather naive to assume customers are going to switch from any of the traditional brands and sources to these. If you live in Stoke on Trent why would not just go to Boots? Even if you live in the middle of nowhere most established cosmetic companies sell direct on-line.
I use foundation every day and even then I can't remember when I last bought a bottle. Most cosmetics do actually last quite a while.
I don't use social media so I don't know if these companies use a particularly hard sell, maybe they do. Clearly some people fall for it.
