How are before-and-after photos usually taken?

A face lit from the front by soft, even light shows fewer shadows, and shadows are what most people are trying to treat: under the eyes, beside the nose, along the jaw. Move the light to the side and the same face shows every hollow.

A before photograph taken under an overhead ceiling light and an after photograph taken by a window can make an untouched face look transformed.

Clinical protocols fix the light in position, use two matched sources at the same height and angle, and never switch between them. Some practices go further and use a photography booth that controls light, distance and head position at once.

Ask whether the practice uses one, and if not, how it keeps light consistent between visits.

Angle, distance and expression

The standard set is front, right profile, left profile and two oblique views at a fixed angle, with the head positioned so a line from the ear canal to the bottom of the eye socket sits level. That sounds fussy.

It matters because a chin tilted up by a few degrees fills the jawline and shortens the neck, and a chin tilted down does the reverse. Distance changes the face too; a phone held close widens the nose and narrows the cheeks.

Expression is the last variable. Toxin photographs need a set of the face at rest and a set at full frown, raise and squint, taken the same way both times.

Geological surveys photograph the same rock face from the same marked point year after year, so the change they record is real change.

The repeat-photography archives kept by the USGS show why the fixed vantage point is the whole method, and a face deserves no less rigor.

Timing the after photograph

An after photograph taken immediately after filler shows swelling, and swelling flatters. It fills lines and lifts cheeks for a few days, then goes down.

The honest after is taken when the product has settled, at two to four weeks for most fillers and at about two weeks for toxin, when the muscle effect has fully arrived.

A gallery whose after images all show fresh injection marks or a slight sheen of swelling is showing the product at its most flattering hour, not the result the reader will live with.

Consent, storage and who owns the images

Clinical photographs are part of the medical record. A practice should ask for written consent to take them, and for separate written consent to use them in marketing, with the option to decline the second without affecting care.

Ask how the images are stored, who can see them, and whether the reader can have copies. Institutions that hold images of many people, such as the Los Angeles Unified School District, keep written rules that make the two uses distinct.

A clinic should be able to describe its own policy in the same plain terms.

Next steps

Before treatment, ask how photographs are taken, whether a booth or fixed lighting is used, when the after set will be taken, and whether the reader receives copies.

Take a set at home too, in the same spot by the same window at the same time of day, with the phone at arm's length on a stand.

Then when a clinic gallery is offered as evidence, apply the test: same light, same angle, same expression, same makeup, settled timing.

Galleries that pass are rare, and a practice whose own photographs pass has told a reader something about how it works.

How the desk checked this answer

The desk read the clinical photography standards that dermatology and plastic surgery bodies publish for their members, then compared them with the galleries on Los Angeles clinic websites. The gap is wide. Standardized clinical photography is a settled discipline with written protocols.

Marketing galleries often follow none of it. This answer describes the protocol so a reader can judge a gallery against it and can insist on it for their own record.

The desk cannot vouch for any particular clinic's photographs, and a reader should treat every gallery as an exhibit to be examined rather than a result to be expected.
