Face Age reads a photo for cosmetic concerns and Skin Age, then maps products you configured. Garbage lighting in, wobbly scores out. Not a medical diagnosis; does not replace a dermatologist.
Key terms: Usable scan means concern scores stable enough to drive product rules. Front light means the light source sits near the camera, facing the shopper. Framing means how much of the face fills the capture box.
Why photo quality is a merchandising problem
Merchants blame "the AI" when recommendations look off. Often the input was a selfie taken under a kitchen downlight with half the face in shadow and a beauty filter still on. Your product rules never got a fair concern profile. Fixing photo guidance is cheaper than remapping the whole catalog.
Put tips in three places: a one-screen interstitial before camera permission, a line under the scan CTA, and a short FAQ on the page that hosts the section or modal. Placement context: modal vs section.
Lighting: what to tell shoppers
| Situation | Usable? | What to say on-store |
|---|---|---|
| Face a window in daylight, no harsh sun on one cheek | Yes | "Stand facing a window. Soft daylight is ideal." |
| Ring light or desk lamp behind the phone | Yes | "Light should hit your face from the front, near the camera." |
| Bathroom mirror with bulb above the mirror | Risky | "Move the light so it is not only from above — overhead bulbs carve shadows under eyes." |
| Backlit by a bright window behind the head | No | "Don't stand with a bright window behind you. Your face goes dark." |
| Colored LED / club lighting | No | "Skip colored lights. They tint skin and confuse tone readings." |
| Golden-hour sun from the side | Risky | "If the sun is strong, turn so both cheeks get similar light." |
You do not need studio gear. You need even front light. In retail kiosks, tape a note on the iPad stand and fix a cheap ring light - inconsistency across stores is worse than a modest setup everywhere.
Framing and camera habits
- Fill the frame with the face. Chin near the bottom edge, forehead near the top, ears visible if the crop allows. The capture UI usually shows a guide oval - teach shoppers to match it.
- Hold the phone at eye level. Shooting from the lap foreshortens the nose and darkens the eyes. Shooting from above is an Instagram habit that hides the jaw and changes how texture reads.
- Look at the camera lens, not the preview eyes. Slight, but it keeps gaze consistent across return scans when you use compare.
- Neutral expression, eyes open. Big smiles bunch crow's feet and change how lines read. Squinting under sun does the same.
- Hair off the forehead and temples. Bangs that cover half the brow steal signal. A quick tuck is enough.
- One face, no second person in frame. Group selfies and mirror-with-partner shots confuse detection.
- Stillness for a beat. Motion blur from a hurried tap is a silent killer on older phones.
For returning skincare customers using history and compare, repeatable framing matters as much as "pretty" framing. A slightly imperfect but consistent setup beats a glamorous new angle every month. Pair with the returning-shopper playbook once that post is live, or with before-and-after compare explained.
Makeup, skincare and filters
Bare face is best. Say it kindly. Full foundation, heavy contour and glitter primers hide the exact cues (texture, redness, uneven tone) that product mapping needs.
Light tinted moisturizer or SPF is usually acceptable for a casual scan; still ask for bare when you can.
Turn off beauty filters and "smooth skin" camera modes. iOS and Android both ship aggressive defaults. Your interstitial should say: "Turn off Portrait/Beauty mode for this scan."
Freshly applied acids or retinoids that leave temporary redness can nudge scores. You do not need to ban them; just know a scan five minutes after a peel pad is not a great baseline for compare.
Sunglasses, heavy frames sitting on cheeks, sheet masks - remove them. Occlusion is not mysterious; the model cannot score what it cannot see.
Device and environment checklist for your team
Use this when QA'ing a new theme install or a pop-up shop iPad:
- Camera permission copy explains why you need the photo (cosmetic analysis + product match).
- Tips screen appears before the shutter, not after a failed result.
- Test on an older mid-range Android and a current iPhone - both should produce a complete result in normal indoor light.
- Test with and without the store's accent lighting on.
- Confirm the privacy policy link is one tap away from the scan CTA.
- Confirm the result screen still shows the cosmetic disclaimer: Not a medical diagnosis; does not replace a dermatologist.
- If you use Server API history, test a second scan on another device after email login.

Copy you can paste near the CTA
Short version for a modal subtitle:
"Use front daylight or a ring light. Bare face if you can. Fill the oval, hold at eye level, turn off beauty filters."
Longer version for a dedicated scan landing section:
"For a usable reading, face a window or soft lamp, keep both sides of your face evenly lit, and take the photo without makeup filters. Hold the phone at eye level so your forehead, cheeks and chin all sit inside the guide. This is a cosmetic skin analysis for product guidance - not a medical diagnosis; it does not replace a dermatologist."
What not to promise in photo tips
Do not tell shoppers a perfect selfie guarantees a perfect routine. Do not imply the camera finds disease. Do not publish accuracy percentages you cannot source. Do not require a $300 lighting kit. The goal is fewer unusable uploads, clearer concern scores, and product rules that get a fair input - then history, PDF and email can do their jobs for people who come back.

FAQ
What lighting works best?
Even front daylight or a soft ring light. Avoid backlight and harsh overhead-only bulbs.
Makeup on or off?
Bare face when possible. Turn beauty filters off either way.
How should the face sit in frame?
Fill the guide oval at eye level, hair off the forehead, neutral expression.
Can a bad photo mess up recommendations?
Yes - skewed scores feed skewed product maps. Tips before the shutter fix more than people expect.
Is this a medical photo exam?
No. Not a medical diagnosis; does not replace a dermatologist.
Special hardware required?
No. A phone camera in decent light is the normal Shopify path.
