Gym, tan, injections? In pursuit of perfect looks, American teenagers turn to peptides.

Key Points:

• A growing number of American teenagers, like 16-year-old Ben, are using unapproved peptides—short chains of amino acids—to enhance their appearance, influenced by social media trends and wellness culture despite the lack of FDA approval or clinical testing.
• The peptide trend gained momentum following the popularity of FDA-approved injectable GLP-1 drugs for diabetes and weight loss, which normalized self-injection and sparked interest in a wider range of peptides marketed for various aesthetic and health benefits.
• Teens involved in "looksmaxxing," a social media-driven movement focused on optimizing physical appearance, often turn to peptides despite unknown safety profiles, with some influencers openly promoting and profiting from these substances.
• Medical experts caution that adolescent peptide use is uncharted territory with potential risks, as these substances affect hormone pathways critical to development and lack rigorous scientific evaluation for safety or efficacy in young people.
• Parents and healthcare providers are encouraged to engage in open, nonjudgmental conversations about body image pressures and peptide use with teens, as the trend reflects broader anxieties about appearance and social acceptance in today's culture.
