Take a comparison photo you can trust
Use a clear, front-facing photo with even daylight if possible. Keep the camera height and face angle the same for both looks. Harsh shadows or a warm bathroom bulb can change the apparent color enough to make a comparison misleading. If you try a second hairstyle or filter at the same time, you will no longer know which change made the look feel different.
Write the occasion first: daytime work, an evening event, or a quick daily routine. Then choose one decision, such as softer eyes versus a stronger lip. This prevents a long gallery of attractive images from turning into a shopping list with no purpose.
Use a short look scorecard
For each preview, note four things: the feature you changed, products you already own, products you would need, and effort to reproduce it. Here is an example; the ratings are personal notes, not a measured performance score.
| Question | Look A: soft eye | Look B: bold lip |
|---|---|---|
| Change | Neutral shadow and liner | Existing eye look, deeper lip |
| Own already? | Shadow yes; liner no | Lip color no |
| Time to apply | More practice needed | Familiar routine |
| Test in person | Check liner comfort | Check lip shade and wear |
The best look is the one that fits your real products, time and comfort. A preview is useful as a brief for a makeup artist too: show both versions and say what you like about each.
GILD AI lets you upload a photo and preview makeup looks. Use it to narrow the look you want to try, then verify product shades, ingredients and technique separately. A generated preview is not a product safety test or a guarantee of the real result.

Digital color is affected by screen and lighting. Read ingredient labels if you have known sensitivities; do not assume a “hypoallergenic” label guarantees no reaction. The FDA’s cosmetics allergen guide explains why products can cause reactions and why label reading matters. Stop using a product that causes a reaction and seek medical advice when appropriate.
Do not upload someone else’s face without permission. Keep an original unedited photo alongside the preview so a real makeup artist can see your starting point. If you are buying a complexion product, test it in actual light on your skin; pixels cannot reproduce undertone or oxidation reliably.
Where GILD AI fits
GILD AI is a quick way to explore makeup directions on your own photo. Choose a look you can realistically recreate, then use the preview as a conversation aid. The App Store listing describes photo-based AI makeup try-on. It does not claim to verify cosmetic ingredients or predict a physical shade match.

Questions answered
Can a virtual look tell me which foundation shade to buy?
No. Lighting, camera processing and screen color can shift the result. Test the actual product under useful lighting.
Should I compare many changes at once?
Compare one defining change at a time so you can explain what you prefer.
Does a preview prove a product is safe for me?
No. Check the product label and your known sensitivities; a preview does not assess allergy risk.
