Laser resurfacing for pigmentation: what to know

Uneven colour can follow sun exposure, acne or irritation, hormonal change, medication, or an underlying skin condition. A clinician should examine a new, changing, bleeding, or unusual spot before treating it cosmetically. Resurfacing can remove or remodel pigment-containing surface layers, yet heat and inflammation may make some skin temporarily darker or lighter. The treatment choice depends on pigment depth, skin tone, recent sun exposure, and whether the trigger is still active.

Tell the clinician about recent tanning, pregnancy or hormonal treatment, acne, eczema, medicines, and prior pigment changes after procedures. Follow the preparation plan exactly and avoid adding strong exfoliants unless approved. After treatment, use gentle cleansing and the recommended barrier care, never pick peeling areas, and protect healed skin from ultraviolet exposure. Ask whether a non-laser option such as a [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/) fits your pigmentation.

Call the treating clinic for increasing pain, spreading redness, pus, fever, blisters, or a wound that is not healing as expected. Arrange prompt assessment for a spot that changes shape or colour, bleeds, crusts repeatedly, or becomes persistently tender. Urgent help is appropriate for facial swelling with breathing difficulty or a rapidly spreading reaction.
