Common skin effects of Wegovy
According to the prescribing information for Semaglutide, common skin reactions include mild rash, dryness, mild itching, transient flushing and (for some agents) photosensitivity that makes the skin more sensitive to UV. Wegovy acts on the GLP-1 receptor in the central nervous system and gastrointestinal tract to reduce appetite, slow gastric emptying and increase satiety. Most are mild, appear in the first weeks and resolve without intervention or with simple measures (moisturiser, sunscreen).
