INTRODUCTION
As diabetes mellitus medications with weight loss benefits become increasingly popular, non-diabetic patients turn to medications like Ozempic® and Wegovy® (generic semaglutide) for a similar intervention. Only Wegovy® has been approved by the United States (US) Food and Drug Administration (FDA) for chronic weight management in patients who have a body mass index (BMI) greater than or equal to 27 kg/m2 and at least one weight-related condition (e.g., hypertension, type 2 diabetes, cholesterol) or in patients with a greater than or equal to 30 kg/m2 BMI.1
Increasing use of these medications has generated the emergence of the term "Ozempic face" across social media platforms as diabetic and non-diabetic patients experience adverse effects. The term describes the extreme weight loss in the face leaving distorted contours of facial anatomy and skin sagging.2 Semaglutide, a glucagon-like-peptide 1 (GLP-1) agonist, is indicated for type 2 diabetes mellitus and may be preferred in patients with comorbidities such as atherosclerotic cardiovascular disease (Ozempic®).3 Side effects of GLP-1 agonists include nausea, gastrointestinal upset, pancreatitis, and weight loss.4 Although known to cause weight loss, the relationship between the GLP-1 agonist mechanism of action and facial weight loss is not characterized and may be unrelated. Our review of normal physiological responses to weight loss aims to demystify the "Ozempic face."
Known GLP-1 Agonists and Weight Loss
GLP-1 agonists increase glucose-dependent insulin release, decrease glucagon secretion, and reduce gastric emptying, promoting an increase in patients' satiety.5 Evidence of GLP-1 agonists favoring adipose catabolism of the face, as opposed to other body regions, is lacking.3,5,6 In addition to lifestyle modification, GLP-1 agonist use for the treatment of type 2 diabetes mellitus may yield an average of 17.6% weight loss versus 2% weight loss with lifestyle modification alone for 68 weeks.3
Adipose and Facial Contour
Elastin, a main component of the dermal skin layer, allows skin to stretch and recoil.2 Over time, elastin turnover decreases and can be damaged by various factors including ultraviolet (UV) radiation.2,6 When patients receive a GLP-1 agonist known to increase weight loss, concurrently with a natural decline in elastin turnover, the lack of recoil and loss of subcutaneous fat can produce wrinkling and sagging; this effect may have gone undetected until the addition of GLP-1 agonist. There is no evidence that subcutaneous adipose tissue is more likely to be catabolized compared to other adipose stores.
A Dermatologist's Role
Dermatologists must ask about concomitant medication use when consulting patients requesting facial fillers. Given the ongoing social media phenomenon, physicians must consider recent weight loss with GLP-1 agonists as patients attempt to combat the wrinkling and sagging effects caused by rapid weight loss. According to the American Academy of Dermatology, facial fillers provide immediate results to replace and combat skin elasticity and can last between two months to indefinitely.7 Dermatologists must anticipate an emerging patient population seeking fillers after GLP-1 agonist use and explain realistic expectations with medication use, weight loss,
