This selectivity is often highlighted when comparing their potential side effect profiles and overall application
Key points: In the only head-to-head trial, Wegovy produced 15.8% weight loss compared with 6.4% for Saxenda over the same 68-week period Wegovy 7.2 mg (approved January 2026) produces even greater results at 20.7% average weight loss Real-world data from Second Nature shows 19.1% weight loss with semaglutide when combined with behavioural support Semaglutide participants were nearly three times more likely to achieve at least 10% weight loss than liraglutide participants Side effects and tolerability Both medications share a similar side-effect profile, predominantly affecting the gastrointestinal tract

It's information you should have before you decide

Here's the clinical summary: Mechanism: GLP-1 receptor agonists can cause nausea-related reduced oral intake and altered skin hydration dehydrated skin is more susceptible to UV damage and less able to repair UV-induced DNA strand breaks Weight loss & UV sensitivity: Significant weight loss (common with GLP-1 medications) can expose areas of skin previously shaded by body fat new UV exposure patterns emerge as body composition changes Drug interaction risk: Many GLP-1 patients are also on metformin, statins, or ACE inhibitors all of which carry independent photosensitivity risks that compound with GLP-1 effects Outdoor exercise motivation: GLP-1 medications often increase motivation for outdoor exercise as energy levels improve patients starting new outdoor routines should simultaneously begin UV protection habits Practical protection priority: For patients using GLP-1 medications for weight management who are increasing outdoor activity, a UPF 50+ umbrella provides consistent, sweat-free UV protection during walks, outdoor exercise, and recreational activities Ozempic & Sun Sensitivity: Expert FAQ Does Ozempic (semaglutide) cause photosensitivity as a direct side effect
