How to Take a Photo for a Lip Filler Preview

Take a clear photo for a lip filler preview: camera distance, lighting, relaxed lips, upload requirements, and checks before comparing AI-generated looks.

Use this to prepare for a consultation. It is not medical advice.

In short

Use a clear, front-facing photo with relaxed lips, even light and no beauty filter. Keep your face visible and use that same image for each comparison. A close selfie, a changed expression or heavy lip liner can make it harder to tell what the preview has changed. This guide helps you choose a useful starting photo and recognise when an AI result is a poor comparison.

Set up a clear starting photo

LookPrep's photo guidance asks for a forward-facing view, relaxed lips, even natural light and no heavy lip makeup. A phone is enough. Set it up so you can look straight ahead without stretching an arm toward your face.

The American Academy of Dermatology recommends good light, a plain background, disabled filters and sharp detail for photographs sent to a dermatologist. Those are useful image-quality principles here too; they do not make an AI preview a medical assessment.

  • Face a window or another soft light source. Check that neither side of your mouth disappears into shadow.
  • Keep the camera level with your face and your head facing forward.
  • Let your lips rest naturally. Avoid a deliberate pout, broad smile or tightly pressed mouth.
  • Leave off lip liner, lipstick and gloss so the outline is visible. Move hair away from your mouth.
  • Check the saved photo once for focus, glare and cropping. Keep the original.

A sharp, relaxed, evenly lit face

What to do
Keep this photo.
Why it helps
You have a workable starting point; it does not need to be your favourite portrait.

Extra background around a clear face

What to do
Use the crop step, keeping your face and lips visible.
Why it helps
Framing can be adjusted without redrawing your features.

Blur, a turned head or a posed pout

What to do
Take a new photo.
Why it helps
Cropping cannot restore missing detail or change the view.

A beauty filter or reshaped lips

What to do
Return to an unedited original or retake.
Why it helps
An already altered outline makes the starting point unclear.

Choose the smallest useful correction before uploading.

Why a close selfie can change how your lips look

A camera turns a three-dimensional face into a flat image. A published proposal for aesthetic photography standards illustrates how changing camera distance changes facial proportions in the photograph. It also stresses consistent camera angle. The practical implication is that a close, tilted selfie and a straight-on photo taken farther away are different starting points.

If the phone is very close, try placing it farther away on a stable surface and using a timer, or ask someone to take the picture. Keep enough detail to see your lip outline. There is no single distance in this guide that guarantees a distortion-free photo.

Zooming into a saved picture changes its crop, not the position from which it was taken. A front camera can still produce a usable image; switching cameras alone does not solve a close-up angle. Avoid deciding that your lips need changing because of one unfamiliar photograph.

Retake the photo only when something useful is missing

Use the table to separate a framing problem from a missing-information problem. A clear face with spare background can be cropped. A blurred lip edge, hair across the mouth or a strong turn of the head calls for another photograph.

Do not reshape, smooth or make your lips more symmetrical before uploading. That would change the baseline you are trying to compare. If the photo is sharp and matches the setup above, you can stop taking pictures. The aim is a stable reference, and a neutral photo is allowed to look ordinary.

A photo taken after treatment is a different starting point from one taken before it. An AI preview cannot assess a recent treatment or tell you whether a change needs care. Take treatment concerns to your provider.

What photo files does LookPrep accept?

LookPrep accepts JPG, PNG, WebP, HEIC and HEIF photos. Its current upload checks allow files up to 12 MB and images up to 25 million pixels. The crop needs enough detail for at least 320 pixels across and 400 pixels high. These are file requirements, not a promise of preview quality.

Choose the original photo from your camera roll where possible. A screenshot of a social post may already contain filters, a tight crop or lost detail. During LookPrep's crop step, keep your face and lips clear rather than filling the frame with only your mouth.

If an image is too large, export a smaller copy while keeping the original. If it is too small or blurry, use a better original instead of enlarging it and expecting new detail. Follow the upload message if a file is rejected.

Review the photo-processing consent before continuing. If you would rather explore without supplying your own photo, start with a stored demo face. A demo helps you learn the controls; its appearance is not evidence of how a look would suit you.

Check the generated preview before choosing a favourite

A suitable input photo does not guarantee a suitable output. Compare every preview with the exact original used to create it. First check what stayed the same; then decide whether you like the illustrated lip change.

If the preview changes your expression, teeth or unrelated facial features, set that output aside. You cannot tell whether you preferred the lip change or the extra changes. A more polished-looking image is not automatically a more useful reference.

Keep the same source photo while comparing looks. If you replace it, treat the new images as a separate comparison set. Otherwise, a difference in the starting photo can be mistaken for a difference between preview settings.

  • Can I recognise the same expression and surrounding features?
  • Can I name the lip change without relying on altered teeth, lighting or skin?
  • Can I point to both something I like and something I want to keep unchanged?

Bring the original as well as the preview

Take the source photo, one useful preview and a short note to your consultation. Label the preview as AI-generated. For example: I like the clearer upper-lip outline here, but I want to keep my existing shape. Please explain what is realistic and what this front view leaves out.

LookPrep works from a front-facing photo. It cannot establish the result in profile, movement, swelling or healing, and its product and amount settings do not prescribe treatment. The FDA explains that filler outcomes depend on underlying tissue structure and the type and volume of filler used.

Ask the provider what other views or information they need. Follow the clinic's own photography instructions for clinical records. A useful preview can help you describe a preference; the consultation may still lead to a different plan, waiting or no treatment.

Questions to take to a consultation

Bring these as written. A good provider will welcome them, and the answers tell you as much as the treatment does.

  1. 1.Does this photo give you enough context, or do you need separate profile and smiling views?
  2. 2.Which parts of my preferred preview are realistic for my own lips?
  3. 3.What does this front-view image leave out that should affect my decision?

Common questions

No. A clear phone photo can provide the starting image. Check the saved picture for visible lip detail, a relaxed expression and an unobstructed face before uploading.

See the difference on your own photo

Compare the directions privately on your own face, then bring the preferences, not a promised outcome, to a qualified consultation.
