Here’s another reason for Gwyneth Paltrow’s haters to come out in droves: the $85 skin cream she’s now endorsing is reportedly on par with brands found at the bottom of the shelves in your local drugstore. Paltrow is now appearing in print ads for Restorsea, which contains brown algae and an enzyme from salmon eggs. But despite the fancy ingredients, scientists say the skin cream is no better than an ordinary moisturizer and have criticized the lack of extensive beauty testing before bringing the product to market.

“I love how it smells, that it works,” says Paltrow in the skin cream ad. “And the fact it is a brand started by a woman entrepreneur. I never promote anything that I don’t use, love and believe in.” But several dermatologists in London slammed Restorsea for displaying little evidence that it worked and not undergoing rigorous clinical tests. They also said the sample size of 40 used to test the skin cream was too small, claiming hundreds of people need to be tested for “statistically significant” results.

“I think once again we are being seduced by a so-called ‘miracle product’ that happens to have a great celebrity endorsement,” said skin expert Louise Thomas-Minns. A spokesman for Restorsea said the product has undergone adequate testing and that “clinicians saw statistically significant improvement to the skin after two, six and 12 weeks.”

Of course, this isn’t the first thing Paltrow has endorsed that has received criticism. Her GOOP holiday gift guide last Christmas was slammed as a pretentious list of items not worth the money. Some of the gift suggestions included a $1,200 membership in the exclusive Orin Swift wine club and a $5,800 set of kitchen tools by Malle W Trosseau.

After her cookbook, It’s All Good, was released last year, Paltrow was also criticized for revealing that she didn't allow her family to eat gluten, dairy and chicken eggs. She admitted to keeping carbs away from her children. "Sometimes when my family is not eating pasta, bread or processed grains like white rice, we're left that specific hunger that comes with avoiding carbs," she says in the book. Most reviews slammed the book, with The Atlantic Wire writing that Paltrow “takes laughable Hollywood neuroticism about eating to the next level.”
