What should you know about q switched 532 nm laser?

The 532 nm wavelength is absorbed by particular colours more readily than by others. A clinician may consider it for a suitable superficial pigment concern or selected tattoo pigments after examining the skin. It is not interchangeable with every laser wavelength, and deeper pigment may require a different approach. Temporary redness, pinpoint crusting, swelling, or a change in skin colour can occur while the area heals.

Tell the clinician about recent sun exposure, tanning products, active irritation, medicines, cold sores, and previous pigment changes after injury. Follow instructions for cleansing and ointment, do not remove crusts, and keep the area shielded from sunlight. Pause exfoliating acids, retinoids, and fragranced products until the clinician says the surface has recovered.

Contact the clinic if discomfort is escalating, redness spreads, swelling becomes pronounced, or the area develops blisters, pus, fever, or increasing warmth. A changing or unexplained pigmented lesion needs medical examination rather than cosmetic laser alone. Seek urgent help for facial swelling with breathing difficulty.

Ask why 532 nm is being selected, what alternatives fit your concern, whether a test spot is advisable, how your skin tone affects pigment-change risk, and which products should be stopped around treatment.
