If you're a person who loves to have baby-butt-smooth skin, chances are you've rubbed this stuff on your face a few times.
But not everyone is so hype for the scrub.
Now, two women are suing Unilever. They claim the crushed walnut shells in the scrub "damage the skin in a way that makes it completely unsuitable for use in a skin care product."
A Unilever spokesperson responded with the following statement to BuzzFeed News:
As a general practice we do not comment on pending litigation. We can say that for over 30 years, consumers have loved and trusted the St. Ives brand to refresh and revitalize their skin. We are proud to be America’s top facial scrub brand and stand by our dermatologist tested formula.
Dr. Joshua Zeichner, a New York–based dermatologist, told BuzzFeed News that the "qualities of a skin care product and the way that they are used are two separate issues."
"Over-exfoliating with any type of scrub or chemical exfoliator like salicylic acid or glycolic acid may result in skin inflammation," he said. "If you have dry or sensitive skin, you may want to steer clear of exfoliators all together."
Zeichner said the scrub would have had to pass certain tests and "demonstrate that it does not block pores" to be labeled as non-comedogenic.
"There are many different scrubs on the market, ranging from coarse to fine particle physical exfoliating scrubs. It is important to select a product that best suits the specific needs of your skin," he said. "If you've any questions, you can certainly touch base with your dermatologist for advice on the best product for you."
