Melasma vs Pigmentation — What's the Difference & How We Treat Each

Why the Distinction Matters

At Krisara Skin Clinic, one of the most frequent clinical errors we encounter from patients who have sought treatment elsewhere is misidentifying the type of pigmentation they carry. Treating melasma with aggressive laser protocols designed for post-inflammatory hyperpigmentation, for example, can cause a dramatic rebound darkening. The biology of each type of pigmentation is distinct, and so must be the clinical response.

Understanding Melasma

Melasma is a chronic, hormonally driven pigmentation disorder that appears as symmetrical, irregular patches—most commonly on the cheeks, upper lip, forehead, and chin. It is triggered by UV exposure acting on melanocytes that have been made hypersensitive by estrogen and progesterone fluctuations. This is why it is so prevalent in women, particularly during pregnancy, oral contraceptive use, or perimenopause.

Crucially, melasma is a condition to be managed, not cured. The melanocytes retain their heightened reactivity even after successful treatment. Without diligent photoprotection, melasma will recur. This is why our approach at Krisara Skin Clinic is built around stabilization, not just clearance.

Post-Inflammatory Hyperpigmentation (PIH)

PIH occurs when inflammation—from acne, injury, chemical irritation, or aggressive treatments—triggers excess melanin production as the skin heals. Unlike melasma, PIH is not hormonally driven and will often fade naturally over months, though clinical intervention dramatically accelerates resolution.

PIH responds well to chemical peels, vitamin C serums, niacinamide, and careful use of Q-Switched laser systems. The key distinction is that PIH is a reactive pigmentation—treat the cause, treat the inflammation, and the pigment subsides.

Sun Damage & Lentigines

Lentigines—or sun spots—are discrete, well-defined flat brown spots caused by cumulative UV damage. They have a sharply defined border, occur on UV-exposed areas, and are generally easier to clear than melasma. Targeted Q-Switched or Pico laser treatments are highly effective with minimal sessions.

Our Clinical Protocol

Dr. Rashmika Reddy uses dermoscopy and skin analysis to accurately classify your pigmentation before any treatment is initiated. For melasma, we combine low-fluence Q-Switched laser toning with stabilizing topicals and strict SPF 50+ protocols. For PIH, we use brightening peels and targeted actives. For lentigines, we apply precise laser energy to shatter melanin clusters.

The single most important variable in pigmentation treatment? Sun protection. Every treatment protocol we design at Krisara is built on a foundation of medical-grade UV protection—without it, even the best clinical intervention yields temporary results.
