Alexandrite laser for pigmentation: what to know

The laser delivers light that is absorbed by pigment, creating heat in the intended target. The treated mark may darken or form a light crust before gradually clearing. Results vary because brown or grey marks can arise from different depths and causes. A clinician should identify the lesion first; a changing or uncertain mark should not simply be treated cosmetically.

Melanin in surrounding skin can also absorb the energy. Recent tanning and naturally deeper skin tones may increase the chance of burns or unwanted lightening or darkening, so device settings and cooling must be chosen for the individual.

Arrange an assessment that covers the mark's history, medicines, previous scarring or pigment changes, cold sores near the area, and recent sun exposure. Ask whether a test spot is appropriate. Avoid tanning before treatment and follow the clinic's instructions about active skincare products rather than stopping prescribed medicine on your own.

Afterward, use gentle cleansing, avoid picking at crusts, and protect the area from sunlight as directed. Contact the treating clinic if you are unsure whether a reaction fits the expected healing pattern.

Promptly contact the treating clinician for worsening pain, extensive blistering, spreading redness, pus, fever, an eye symptom after treatment near the face, or a sore that is not healing. Seek urgent medical care for breathing difficulty, facial swelling, severe eye pain, or sudden vision change. Mild warmth, redness, or swelling can occur, but the expected pattern should be explained before you leave.

Ask what diagnosis is being treated, why this laser fits your skin and pigment type, how eye protection and cooling will be handled, and what colour changes or scarring could occur. Clarify the likely care between visits, what improvement would be realistic, and which reaction should trigger a call.
