Why your pigmentation keeps coming back

Almost every week, someone sits down in our consulting room and says a version of the same sentence: "I had laser for my pigmentation, it cleared, and then it came back — so laser does not work on my skin."

Nearly always, the laser worked. What happened afterwards is the problem.

Pigmentation is a condition, not an event

This is the part that gets lost. Melasma and post-inflammatory hyperpigmentation are chronic conditions driven by melanocytes that are, in a real sense, hyper-reactive. Treatment clears the pigment that is already there. It does not change the tendency of those cells to produce more when provoked.

So the relevant question is not "did the treatment work" but "what happened in the twelve weeks afterwards". And in Gurgaon, what happens is a great deal of ultraviolet light.

The three things that undo a good course

1. Sun exposure that does not feel like sun exposure

Patients apply SPF for a beach holiday. They do not apply it for a twenty-minute school run, a walk to the car park at 2pm, or a window seat in an office. Cumulative incidental exposure is what drives recurrence, and it is almost entirely invisible to the person experiencing it.

2. Heat, separately from light

This surprises people. Melasma responds to infrared and to heat as well as to UV — which means a hot kitchen, a long commute in a warm car, or a steam room can all provoke it even in the absence of direct sunlight. A mineral sunscreen with iron oxide offers some protection against visible light that a chemical filter does not.

3. Stopping the maintenance topical

Once skin looks clear, most people stop. The tyrosinase inhibitor that was suppressing melanin production comes out of the routine, and within a few months the pigment returns. Maintenance is not optional; it is the treatment.

What actually prevents recurrence

In our experience the patients who hold their result do four things consistently. They apply a broad-spectrum SPF 50 with iron oxide every morning regardless of weather or plans. They reapply at midday if they are outdoors. They stay on a maintenance topical — usually at reduced frequency rather than stopped entirely. And they come back for a short top-up course once a year rather than waiting until the pigment has fully returned.

None of that is glamorous. It is, however, the difference between a result that lasts eight months and one that lasts eight years.

When to come back in

If pigment is visibly returning, come in earlier rather than later. A short maintenance course on early recurrence is considerably cheaper, faster and gentler than a full course on established pigmentation. Waiting until it is as bad as it was originally means starting again from the beginning.
