Beauty ads compare two different photos. SameLight makes them compare two faces.
Paste a before and after ad. SameLight brings both photos to the same focus, exposure and colour, then measures the skin again with YouCam Skin Analysis. You see how much of the promise is left.
One screenshot with both faces works too. Press Ctrl+V anywhere on this page.

Your photo goes to YouCam for this one analysis. SameLight stores nothing.
How the check works
- Line up. MediaPipe finds both faces in your browser, then levels and scales them to the same size.
- Match the camera. Eyes, brows and lip edges do not change with skincare, so any loss of detail there is the camera. The sharper photo is softened until those parts match, and the eyes set exposure and colour.
- Measure twice. YouCam Skin Analysis scores the pair as published and again under the same light.
Tested before launch
Each test is a known answer: camera tricks with no skin change, a real skin change made with YouCam Skin Simulation, and an untouched copy of the same photo.
Scores are added across six measures. Test faces are AI generated with YouCam.
