The law requires models to present a doctor's certificate certifying their body is healthy and forces publishers to designate photoshopped images as a "photographie retouchée" (or retouched photograph).
There have also been repeated complaints that fashion houses in general promote unhealthily thin body shapes and claims that models are sometimes placed under pressure to maintain unhealthily low weights.
"We hope to inspire the entire industry to follow suit, thus making a real difference in the working conditions of fashion models industry-wide", he added.
Another French model, Isabelle Caro, fronted a shocking anti-anorexia campaign during Milan fashion week in 2007 before she died from the disease three years later at the age of 28.
A therapist will be on hand during work hours for the models' care, and models will have to present a medical certificate declaring their health within six months of a fashion show or shoot.
"Having always cared for the well-being of models, LVMH and Kering feel that they have a specific responsibility, as leaders in the industry, to go one step further with their brands".
Models aged 16 to 18 will not be allowed to work between 10pm and 6am and must be accompanied by a guardian or chaperone who is housed with them during jobs.
"A young girl of 15 years old does not have the necessary experience to deal with the hard world of modelling", Antoine Arnault, son of LMVH director Bernard Arnault and a member of the company's management, said. This project was put in place by the two major fashion firms LVMH and Kering, which look after a string of prestigious label, including Givenchy, Yves Saint Laurent, Alexander McQueen, Marc Jacobs, Fendi and Stella McCartney. "A young girl of 15 doesn t have the faculties to take on the hard world of fashion and modelling", he said.
Danish model Ulrikke Hoyer said she had been asked to starve herself in the run-up to a show.
Arnault said he hoped the guidelines would be fully implemented by the autumn-winter fashion shows in spring 2018.
