Matched photo guide
How to take consistent before-and-after skin photos.
A fair comparison starts before the shutter. Match the conditions that can change how texture, tone, shine, redness, pores, and fine lines appear in a photo.
Short answer
Repeat the setup, not just the selfie.
Use the same phone, lens, room, diffuse light, camera height, distance, head position, expression, time of day, and point in your skincare routine. Keep the image sharp, turn off filters and beauty effects, and retake when the conditions do not match.
Build one repeatable setup
Remove the biggest sources of visual noise.
Light
Choose bright, even, diffuse light. Daylight can work when it is repeatable, but avoid direct sun, window shadows, and mixed warm/cool bulbs. Do not switch between flash and no flash.
Camera
Use the same phone and the same front or rear lens every time. Clean the lens and avoid portrait mode, beauty effects, digital zoom, or any setting that changes skin rendering.
Position
Put the camera at the same height and distance. Mark where the phone and your feet go, or use the same tripod and timer position.
Timing
Photograph at the same time of day and at the same stage of your routine—for example, before applying products or the same interval after cleansing.
The capture sequence
Use the same order every time.
Prepare the scene
Use the same plain background and light source. Pull hair away from the same areas of your face and remove anything that changes the view you intend to compare.
Set the phone
Select the same lens, keep the phone upright, and place it at the saved height and distance. A timer or stable support reduces movement.
Match the pose
Center your face, hold a neutral expression, and repeat the same straight-on and side angles. Do not tilt toward whichever light looks more flattering.
Check focus and exposure
Tap the face to focus if needed. If the image is soft, blown out, shadowed, or unusually bright compared with the baseline, fix the setup and retake.
Keep the original
Do not smooth, recolor, sharpen, crop differently, or apply a filter. Compare original images at the same size and framing.
Before you compare
Ask whether the photos match before asking what changed.
Solid match
Lighting, framing, pose, timing, and image sharpness are close enough to support a cautious cosmetic comparison.
Retake
A large difference in brightness, angle, scale, expression, focus, or skincare stage can explain the apparent change on its own.
Clinical photography guidance from NHS dermatology services emphasizes good lighting, clear focus, and consistent context. Those recommendations are designed for clinical images, not cosmetic progress scoring, but the same fundamentals help reduce misleading differences in self-comparison photos.
Photo handling in Works On Me
Know what is local and what is processed.
Optional routine photos saved in Works On Me remain on your device. A scan selfie is sent through Works On Me to a third-party AI provider to generate the report; Works On Me does not persist that selfie on its servers, and the provider may retain API data for up to 30 days. Read the Privacy Policy before scanning.
Progress photos and Works On Me reports are cosmetic tracking tools, not a way to diagnose a rash, lesion, infection, or other medical concern. Seek qualified medical care when you need clinical assessment.
