Does picosecond laser treatment treat cafe-au-lait spots?

Cafe-au-lait spots are flat, light-brown to medium-brown areas of increased pigment. A picosecond laser sends very short pulses toward pigment in the skin, where the energy can fragment targeted pigment for gradual clearance. The result depends on the spot's colour, depth, location, and the person's tendency to develop lighter or darker marks after treatment.

A spot may fade without disappearing fully, and pigment can return after treatment. Temporary redness, swelling, crusting, or altered colour may occur. Multiple visits may be considered, but the clinician should explain the likely course for the individual spot rather than promise a fixed outcome.

Have the spots examined by a dermatologist, particularly if they are numerous, changing, raised, or accompanied by other unusual skin or nerve symptoms. Share photographs from earlier years if available and mention family history, prior laser treatment, and any history of pigment changes after wounds.

Discuss a test area, eye protection, cooling, aftercare, and sun avoidance. Do not pick at crusts or use strong exfoliants while the skin heals. Arrange follow-up to assess fading and to decide whether further treatment is appropriate for that specific spot.

Seek medical review for a cafe-au-lait spot that changes quickly, becomes raised, bleeds, crusts, or develops several colours. After treatment, contact the clinic for increasing pain, spreading redness, pus, blistering, or a marked colour change that does not settle. These findings need examination rather than another cosmetic session.

Are these spots typical cafe-au-lait spots? What degree of fading is realistic for their colour and depth? Could treatment cause a lighter or darker mark in my skin? Would a test spot be appropriate? How will you monitor for recurrence or changes?
