What this trial means for you
This study is opening soon at 1 US site. It's studying GLP-1 Receptor Agonists for facial skin aging, facial volume loss, wrinkle appearance.
What participants typically get: study medication (or placebo, if the trial uses one) and study-related medical care at no cost, plus close monitoring. Compensation for time and travel varies by study, ask the site. Note that in many trials you can't choose your treatment group, and some participants receive a placebo.
The study, in the sponsor's words
Identical twins share the same genes, which makes them a powerful way to study how lifestyle and environment - rather than genetics - affect how faces age. This study builds on a landmark 2009 twin study by using modern three-dimensional (3D) facial imaging, which measures facial shape and volume precisely instead of relying on regular photographs. The study will also look at whether use of GLP-1 weight-loss medications (such as semaglutide or tirzepatide), sometimes associated with facial changes informally called "Ozempic face," is related to measurable differences in facial aging. The study will enroll adult identical twin pairs attending the Twins Days Festival in Twinsburg, Ohio, in August 2026. Participation takes about 30 minutes and happens in a single visit at the festival study booth. Each twin will complete a questionnaire about lifestyle, environment, and medical history (such as sun exposure, smoking, sleep, and medication use) and have a 3D image of their face taken with a non-contact camera system. There is no treatment, no medication, no blood draw or biological sample, and no follow-up visit. Researchers will then compare facial measurements within each twin pair to learn which lifestyle and environmental factors are linked to visible facial aging.
Can you join? The exact criteria
Below is the verbatim eligibility text from the registry. Bring it to your doctor; it's written for clinicians, and your own clinician is the right person to interpret it with you.
Full eligibility criteria (for you and your doctor)
Inclusion Criteria: * Adults aged 18 years or older * Members of a monozygotic (identical) twin pair, with both twins present and willing to participate * Able to provide written informed consent in English Exclusion Criteria: * Age under 18 years * Inability or unwillingness to provide informed consent * Facial conditions or recent facial surgery that, in the investigator's judgment, would prevent standardized imaging * Pregnancy, by self-report Note: Zygosity is established by participant self-report, supported where available by prior DNA testing or physician confirmation. No genetic testing is performed and no biological specimens are collected. Pairs who self-report as dizygotic or are uncertain of their zygosity are recorded as such and analyzed separately from the confirmed monozygotic cohort.
