Instagram is rolling out a number of new features aimed at protecting teens, the head of the social media platform announced Tuesday.

In a blog post, Adam Mosseri said Instagram is taking a stricter approach to the type of posts — including potentially harmful or sensitive content —  recommended to teens, nudging them toward different topics when they’ve been fixated on a particular subject for too long, blocking users from tagging or mentioning teens that don’t follow them, and suggesting young people take breaks from the app.

“Every day I see the positive impact that Instagram has for young people everywhere,” Mosseri wrote. “I’m proud that our platform is a place where teens can spend time with the people they care about, explore their interests, and explore who they are.

“I want to make sure that it stays that way, which means above all keeping them safe on Instagram. We’ll continue doing research, consulting with experts, and testing new concepts to better serve teens.”

Most of the features announced are still being tested or developed, although the “Take a Break” feature debuted Tuesday in the United States, the United Kingdom, Ireland, Canada, New Zealand and Australia.

If someone has been on Instagram for a certain amount of time, the app will ask them to take a break and suggest they set reminders for more future breaks. To ensure teens are aware of the new feature, the app will show notifications suggesting they turn the reminders on.

Mosseri said Instagram also plans early next year to launch tools for parents and guardians to be more involved in their teen’s experience on the platform. The features will include seeing how mfatime their child spends on the app, setting time limits and creating an “educational hub” with tutorials and tips from experts to help parents discuss social media use with their teens.

Instagram, which is owned by Facebook’s parent company, Meta, has come under fire this year since a former Facebook employee, Frances Haugen, leaked tens of thousands of pages of internal research documents to regulators, lawmakers and the media that showed the social media company has been aware that Instagram causes mental-health and body-image problems for some young people, as well as eating disorders and suicidal thoughts, while it has publicly downplayed the negative impacts.

Haugen told a Senate committee in October that algorithms used by Facebook and Instagram tend to recommend content that is more likely to elicit a strong emotional reaction from people, including posts featuring anorexia or fanning the flames of ethnic violence.

Meta has argued that Haugen has mischaracterized the research, that the company is committed to stopping harmful content and that many teens have reported Instagram has helped them more than hurt them

Mosseri wrote Tuesday that the new features have been in the works for “a long time.”

Instagram requires users to be at least 13 years of age, although Meta has acknowledge children often gain access to its platforms by lying about their age. It says it removes accounts if it determines the users are under 13.
