Semaglutide is an injectable drug for diabetes in the class called GLP-1 analogues. Click for my overview of the class. Semaglutide is sold in the U.S. as brand name Ozempic.
Folks with diabetes taking Ozempic found that it promoted fat weight loss. Facial fat tends to fill in wrinkles, hence, younger-looking skin. Loss of fat on the face can make your skin sag and older-looking, more wrinkled, gaunt. That’s so-called Ozempic face.
Semaglutide and others in it’s class are increasingly being used by non-diabetics for weight loss, either as an injection or a pill.
From the esteemed medical journal, People:
To restore volume in a patient’s face, doctors will often perform noninvasive, but expensive, procedures such as injecting Radiesse and hyaluronic acid-based fillers or Sculptra injections, which stimulates collagen production. Doctors can also restore volume with a face lift or by transferring fat from other body parts to the face.

Citing People as an “esteemed medical journal” loses credibility.
