Q-Switch Laser Pigmentation

Q-Switched lasers deliver ultra-short nanosecond pulses that are selectively absorbed by melanin. The pigment shatters into tiny fragments, which either rise to the surface and flake off (for superficial spots) or are cleared by the immune system (for deeper pigment). Multiple wavelengths (532nm, 1064nm) target different pigment depths.

Q-Switch 'laser toning' (low-fluence 1064nm) is one of the safest and most studied treatments for melasma — particularly when paired with a strict topical regime (tyrosinase inhibitors, SPF, sometimes tranexamic acid). However, melasma is chronic and hormonally driven; laser manages it rather than cures it. Honest expectation-setting is essential.

IPL (Intense Pulsed Light) is broad-spectrum light — fast and effective for sun damage on Fitzpatrick I–III but risky on darker skin. Q-Switch is a specific laser wavelength that selectively targets melanin without heating the surrounding skin — safer for Fitzpatrick IV–VI and melasma.

Superficial age spots may clear in 1–3 sessions. Melasma and deeper pigmentation typically need 6–10 sessions spaced 4–6 weeks apart. Maintenance is usually needed — both to address new UV damage and to keep melasma suppressed.

Depending on settings — mild pinkness, darkening of the treated spots (which flake off over 5–10 days), or no visible change at all (for laser toning). Your practitioner will explain what to expect for your protocol.

Yes — Q-switch Nd:YAG at 1064nm is considered the safest laser for Fitzpatrick IV–VI. However, skill and conservative settings matter: we always perform a test patch first and build energy gradually.
