How to treat pigmentation, professionally.

The clinical difference between sun, hormonal, and post-inflammatory hyperpigmentation — and why one protocol does not fit all.

12 April 2026

Pigmentation isn't one condition. It's three.

The visible spot on a 40-year-old who summered in St Tropez is not the same as the diffuse mask on the cheeks of a woman in her second pregnancy. And neither is the brown shadow left where an acne lesion once sat. They look similar. They respond completely differently.

Sun-induced pigmentation

This is what most people mean when they say "dark spots." Discrete, sharp-edged, usually on the cheeks, forehead, hands. They come from accumulated UV damage triggering melanocytes to dump pigment in localized patches.

The fix is mechanical and chemical: reduce active melanocyte stimulation (sunscreen, always), break up existing pigment (vitamin C, resveratrol, alpha-arbutin), and accelerate cell turnover (gentle retinol or AHA in cabin treatments). Visible reduction in 4–8 weeks. Permanent prevention requires consistent SPF for life.

Hormonal pigmentation (melasma)

This is harder. Soft-edged, often symmetrical, frequently triggered by pregnancy, contraceptives, or significant hormonal change. The melanocyte hyperactivity is hormone-driven, not UV-driven — although UV makes it dramatically worse.

The protocol shifts. Aggressive peels and lasers can worsen melasma. The right approach: tranexamic acid, niacinamide, gentle brightening actives, and absolutely religious SPF. Patience is the active ingredient — visible improvement takes 12+ weeks of consistent use.

Post-inflammatory hyperpigmentation

The brown mark left after a pimple, an injury, or an aggressive treatment. The skin's inflammatory response triggers temporary pigment deposit. It almost always fades on its own — but you can accelerate it with the same brightening actives used for sun pigmentation, plus barrier-support products to prevent the inflammation from recurring.

The Dr. Kadir lightening protocol

For all three, we recommend the same baseline routine:

  • AM: Vitamin C → Mesobooster Hyaluron → SPF 50+
  • PM: Resveratrol Drops → Hyalu-Ron Cream
  • Cabin: AHA Retinol Pro every 4–6 weeks (sun pigmentation only — never melasma)

What changes between concern types is the cabin treatment intensity and how aggressively you can introduce retinol at home. Always start gentle. Always SPF.
