GLP-1 receptor agonists are medications used for type 2 diabetes and weight management; their effects on facial volume and skin are an emerging topic in dermatology.
After rapid weight loss on GLP-1 drugs, loose skin on the abdomen, arms, and thighs is common. What the evidence says about energy-based tightening, biostimulators, timing, and when surgery is the realistic option.
Why some patients on semaglutide or tirzepatide notice hair shedding, what pharmacovigilance and review data show, the likely telogen effluvium mechanism, and how it is managed.
Why GLP-1 receptor agonists cause facial volume loss, severity predictors, and the published multimodal restoration approaches in 2026.
