Melasma and facial harmonization procedures

Melasma is one of the most frequent pigmentation disorders in the aesthetics office and one of the most frustrating: it tends to recur, responds to many stimuli and can worsen with procedures that would be well tolerated in another patient. In facial harmonization, the practical point is knowing that melasma is not an absolute contraindication to everything, but it redefines the order of procedures, the possible technologies and the instructions.

This text is a review. It does not prescribe treatment for melasma, which belongs to dermatology, nor does it indicate equipment parameters. Decisions belong to the qualified professional, according to the rules of their professional council. The glossary entry melasma summarizes the definition.

What is melasma and why does it matter in facial harmonization?

Melasma is an acquired, symmetric hyperpigmentation, usually in a centrofacial, malar or mandibular pattern, more common in women and in people with intermediate or darker skin types. Its mechanism involves overactive melanocytes, a vascular component and low-grade inflammation, and not just a "sun spot."

For facial harmonization, three characteristics matter:

1. It is chronic and recurrent. Even when well controlled, it can come back with triggers.
2. It responds to heat and inflammation. Thermal and aggressive procedures can trigger a worsening.
3. It has a strong light component, including visible light, not only ultraviolet.

This changes the professional's question: it is not "can I treat?" but "what in my plan could be a trigger, and who follows the patch?"

What should you ask in the medical history?

Beyond the standard outline in medical history in facial harmonization, investigate:

• Who follows the melasma and what the current treatment is.
• How long it has been present and what phase it is in (controlled, active, recently worse).
• Use of sunscreen, including tinted sunscreen, and sun exposure routine.
• Perceived triggers: pregnancy, birth control pills, hormone replacement, heat, outdoor exercise.
• Previous reaction to procedures, such as laser, peels, microneedling and pulsed light.
• Photosensitizing medications in use.
• Skin type (see the Fitzpatrick classification) and tendency to develop patches after inflammation.

Which procedures call for more caution?

The general logic is: the more heat, light and inflammation, the more caution. The table shows a map of reasoning, not a protocol.

The common point is that technologies that heat the skin are the ones of greatest concern, and that no one should improvise. When in doubt, refer. The relationship between laser and injectables is covered in fractional laser and facial harmonization.

What to do with injectable harmonization?

Filler and toxin are generally not at the center of the concern, but two precautions matter.

Reduce trauma and inflammation

Each procedure should be done with the least possible injury: proper asepsis, appropriate instruments, a suitable number of passes, ice and aftercare instructions. This lowers the chance of post-inflammatory hyperpigmentation, which adds to the melasma. Significant bruising, for example, can leave residual pigment in predisposed skin.

Advise on sun protection

Unprotected sun after a procedure is the worst scenario for skin with melasma. Reinforce the sun protection routine with the patient and, when possible, avoid scheduling stages in periods of unavoidable sun exposure.

How do you explain it to the patient?

The communication needs to make clear that the facial harmonization professional does not treat melasma and that their plan respects the dermatological treatment.

Record the conversation in the patient record and, when there is a referral, follow patient referral in facial harmonization. The informed consent should mention the risk of patches.

How do you organize the plan in stages?

Timeframes and the choice of procedures belong to the qualified professional.

How do you deal with seasonality and recurrence?

Melasma usually worsens in the months of higher radiation and improves in those of lower exposure. For the office, this has two practical consequences. The first concerns scheduling: stages that cause more inflammation tend to be safer outside periods of intense sun, when the patient can protect herself better. The second concerns communication: if the patch darkens after a procedure, it was not always the procedure. A change of season, heat, the use of a certain medication or a hormonal change may explain it. That is why standardized photos before and after and a note of the patch's phase in the patient record prevent unfair attributions, and let you separate natural recurrence from a reaction to treatment.

If darkening appears right after the session and comes with signs of local irritation, consider post-inflammatory hyperpigmentation and review the care routine with dermatology, rather than trying to correct it on your own.

Does Harmy show melasma?

No. Harmy simulates volume in the marked areas and does not alter skin, patches or pigmentation. The app's prompt forbids skin retouching and makeup, so the projection shows only the changes from the marked volume.

This is an honesty advantage: the projection does not promise what facial harmonization does not do. For the flow, see how to use Harmy.

Review quiz

A patient with melasma does not need to be turned away, but does need to be treated with different reasoning. Planning with less injury, reinforcing sun protection, working together with dermatology and promising only what facial harmonization delivers is the safest way to keep a volume procedure from becoming a pigmentation problem.
