Glossier reformulated Balm Dotcom, a star product and fans are voicing their frustration.
Some fans say the lip balm no longer works as well and are accusing the company of ignoring its customers.
Glossier has gone through several changes over the past year, including a new CEO and a deal with Sephora.
The reformulated balm, or BDC as fans call it, will have a redesigned applicator tip and a "new clinically-tested hydrating, vegan formula," Glossier wrote in an Instagram post.
In addition, Glossier is discontinuing the cherry-flavored balm, a popular flavor that had a sheer, red tint.
