Melasma: Understanding the Biology of Pigmentation

Melasma is a chronic pigment condition shaped by hormonal influences, ultraviolet and visible light, heat, inflammation, vascular signalling and barrier health. It is not interchangeable with sunspots or post-inflammatory hyperpigmentation, and the distinction guides every decision that follows.

Daily broad-spectrum protection is the foundation, and visible light matters as much as UV for pigment-prone skin. We favour tinted mineral protection with iron oxides, applied generously and reapplied with exposure, alongside hats, shade and heat awareness. Daylight and outdoor life remain welcome—protected, not avoided.

A comfortable barrier makes pigment care sustainable. Selected ingredients—azelaic acid, vitamin C, tranexamic acid, niacinamide among them—are introduced deliberately and individually, with dermatologist-directed therapies appropriate for persistent cases. A tolerable plan used consistently outperforms an aggressive one that cannot be maintained.

We use Dermapen 4, a mechanical microneedling approach that delivers no radiofrequency heat—a distinction that matters in heat-aware melasma care. Timing and intensity respect pigment history, since post-inflammatory hyperpigmentation can follow skin injury. Heat-based procedures and some laser approaches demand particular caution; sometimes strengthening means waiting until the skin is calmer.

Red and near-infrared photobiomodulation serves as adjunctive care within a broader plan. The melasma-specific pilot involved seven participants in a split-face design combining microdermabrasion with pulsed 940-nm light—promising, and specific to that setting. Pigment-prone skin deserves individualized light decisions, never assumptions.

Maria's own postpartum melasma shaped this studio's patience with pigment. Our framework is Protect → Calm → Repair → Strengthen → Support → Maintain: consistent protection, a settled barrier, meaningful topical care, carefully chosen procedures and maintenance that works through real life. Melasma can recur; maintenance is care, not failure.
