Find out what’s really causing your body’s inflammation—without guessing. AllerGen helps you see how the foods you eat affect your face, skin, and energy. By combining simple photo and meal tracking with AI analysis, it reveals patterns you’d never notice on your own. 1. Take a baseline photo – Capture your normal, rested appearance when you first set up the app. 2. Track your meals – Snap a quick photo of everything you eat. 3. Morning check-ins – Each morning, take a short selfie as soon as you wake up. 4. AI comparison – The app compares each new photo to your baseline, detecting changes like puffiness, redness, or swelling. 5. Discover correlations – Over time, the app highlights which foods most often lead to higher “inflammation scores,” so you can make informed food choices.
