Rapid and significant weight loss induced by Tirzepatide leads to aesthetic changes, including facial volume loss ('Ozempic face'), skin laxity, and altered collagen structure, which are secondary to fat loss rather than direct drug toxicity.
Significant weight loss can cause your face to look older or saggy due to loss of facial fat. This is a side effect of the weight loss, not the drug itself. Eating enough protein and vitamins (like D and B12) during treatment may help maintain skin health.
Rapid or massive weight loss induced by agents like semaglutide and tirzepatide... is associated with a significant reduction in subcutaneous fat tissue volume, predisposing to tissue laxity... Facial lipoatrophy associated with GLP-1-induced weight loss (popularly termed 'Ozempic face') is described as the characteristic facial changes... These changes typically include facial volume and fat loss, skin sagging, hollowing of the cheeks and temples... These aesthetic changes are secondary to rapid weight loss and not a direct pharmacologic toxicity of the drug.
Why this rating
Based on narrative review of case reports and mechanistic studies; causality is indirect (via weight loss).

- Tirzepatide administration (2.5-15 mg weekly) causes injection-site reactions (ISRs) in 2-8% of patients, presenting as localized erythema, swelling, or pruritus, which are generally mild, self-limiting, and comparable in frequency to other GLP-1 agonists.Good
- Tirzepatide use is associated with rare but serious hypersensitivity reactions, including anaphylaxis and angioedema, occurring in approximately 1-4% of patients, often linked to anti-drug antibodies but not always causally related.Good
