Treating top to bottom or bottom to top in facial harmonization

Two good professionals can look at the same face and propose opposite orders: one starts at the forehead and works down; the other starts at the chin and works up. Neither is wrong, as long as the choice has a criterion. This page presents the arguments for each direction, points out the scenarios in which each tends to make more sense and shows how to turn the decision into a record. It does not set a protocol, and clinical decisions belong to the qualified professional, according to the rules of their professional council.

Why does this debate exist?

Because the face is not a sum of isolated areas: what happens in one part changes how its neighbor reads. The logic of aging, with a loss of support that descends, favors thinking top to bottom. The logic of the concern, which is often in the contour or the smile, favors thinking bottom to top. And the logic of risk, which prioritizes less complex areas, can cut across both.

Before choosing the direction, define what guides the plan: the anatomy, the concern or the risk. If that decision is not made, the plan becomes personal preference. The basis for the reasoning is in what to treat first in harmonization and structure before detail in the harmonization plan.

Arguments for treating top to bottom

1. It follows aging. The loss of support in the upper and middle thirds tends to affect the lower third. Restoring support above can change how the lower face reads.
2. It makes the detail decision easier. After adjusting the structure (temples, cheekbone), what remains of the fold or tear trough is clearer.
3. It avoids compensations in the lower face. Treating the chin or jaw without looking at the midface can lead to a heavy lower face.
4. It fits the logic of dynamic lines. In faces with a concern in the forehead and glabella, toxin is usually the first step.

The limit of this direction: the patient's concern may not be at the top, and starting where they did not ask can reduce adherence to the plan. See patient approval of the plan.

Arguments for treating bottom to top

1. It follows the main concern. When the patient comes asking for lips or chin, starting there increases confidence in the plan.
2. Contour before detail. Defining the jaw and chin first frames the rest.
3. Lower risk in some areas. In certain cases, the lower third has less vascular complexity than the midface, which can favor a calmer first session. This depends on the area and the professional.
4. Profile as a guide. In cases of profile disproportion, the chin and lip lead, and the plan climbs from them. See plan to balance the profile.

The limit here: treating the lower face without looking at the midface can leave the set unbalanced, with the jaw and chin standing out over an unsupported midface.

Comparison

The table is not a rule: it serves to make the criterion explicit. No column wins in every row, and the patient's face shows which one weighs more.

And where does risk come in?

In both directions, vascular risk and the risk of complications must guide the order. Areas such as the glabella, nasolabial fold, temples, nose and tear trough require their own planning, and in many cases the professional prefers to start with a less complex area to observe the patient's response before moving on. That is prudence, not a rule.

Possible complications in either direction include swelling, bruising, asymmetry, nodules and, rarely and seriously, vascular occlusion. When hyaluronic acid is used, hyaluronidase must be available. Review prioritizing by risk in the plan and vascular danger zones of the face.

How do budget and logistics interfere?

Patients rarely decide on clinical criteria alone. Budget, schedule, events and tolerance for swelling weigh in. A plan that starts with the most expensive area may drive the patient away; one that starts with the cheapest may postpone what matters most. The honest conversation is: "the ideal is this order; if that is not possible, this is the safest alternative". See prioritizing by the patient's budget and plan for an event with a set date.

When the order departs from the ideal for a patient's reason, record it in the patient record. That protects you and gives a reference for the follow-up.

How does the simulation help with this decision?

In Harmy, you can generate different projections for each order: one with only the midface, another with only the lower face, another with both. Showing two projections side by side helps the patient see which path fits their concern better. The AI respects the volume and changes only what was marked, so the differences are subtle and realistic.

But the simulation does not set any order: it shows a possible end state, not the path. The order remains the professional's decision. In addition, the projection uses a frontal photo, with no profile, which limits its use in contour and projection decisions. It is an illustrative simulation, not a promise of results. See limits of 2D simulation and when the simulation helps in the plan.

Example of a decision record

What to tell the patient?

The line acknowledges that there are alternatives and puts the decision in stages, which reduces anxiety. If the patient wants everything at once, return to the point about risk and recovery time.

Quick review

Summary

Treating top to bottom or bottom to top are two valid logics, and the choice comes from the anatomy, the concern and the risk. Make the criterion explicit, consider budget and schedule, respect the risk areas, record the order and reassess. Harmy's simulation illustrates possible states, but does not decide the path.
