"As a mother of an 8- and 9-year-old I don't want my children growing up looking for flaws or thinking their appearance is some kind of DIY project that needs fixing. With scalpels."
She said the apps were deceptively designed as children's games, encouraging users to slice virtual patients apart using scalpels, syringes and other tools in surgical settings.
"By making cosmetic surgery apps available for download, Apple, Google and Amazon are allowing companies to stoke and profit from the insecurities of children," she wrote.
Barnett said children and teens who viewed a diet of flawless images often ended up questioning their own looks and were more likely to diet and suffer from depression and shame.
She said there was no need for games or apps to add to the problem.
It was important the tech giants implemented a policy making it clear to game developers that they would not accept any apps that were targeted at children.
