GLP-1 Weight Loss Triggers 4 Skin Problems, With Injection Reactions in Up to 20%

Summary
Dermatologists say GLP-1 users are showing skin laxity, facial deflation, telogen effluvium and injection-site complications earlier in weight loss, with several effects often overlapping in the same patient.
Rapid loss above 1 to 2 pounds a week appears to be the main driver, leaving skin less time to recoil and making facial fat loss more visually abrupt; older patients and those with poorer baseline collagen are hit harder.
Hair shedding often starts months later and is usually reversible, but recovery can take up to a year; clinicians are also checking for protein, iron and zinc deficiencies and other alopecias.
Injection-site problems have been reported in up to 20% of GLP-1 users, including persistent painful nodules that may reflect infection and require biopsy and culture, especially with compounded products.
The pattern echoes bariatric-surgery experience and is already feeding demand for cosmetic correction, while dermatologists stress slower weight loss, protein intake, resistance training and early skin-support measures.
