A container of Hydramoist is $30 at my local Sephora, though you can get it cheaper (and more likely to be counterfiet!) online. Most of the other stuff referenced I couldn’t find the exact products (I didn’t try super hard) but they’re in the $10-$20 each range. It’s not bank breaking, but it’s certainly more money than the average ten year old has laying around.
I think this article raises very valid concerns about the extreme influence the beauty industry is having on younger and younger people, and I have no doubt the girls referenced here were subject to that influence, and I am not arguing that influence needs to be much more strictly regulated. In this case, it seems extremely sensationalized to claim that its common for ten year olds to have the resources needed to develop a serious addiction to popular skincare products. Really, it feels like something from the DARE era, but with “marajuana” replaced with “sephora”.
