What to expect from picosecond laser treatment for sun spots

Sun spots are areas of increased pigment linked with cumulative ultraviolet exposure. Before using a laser, the clinician examines the mark and the surrounding skin. A spot that is changing, bleeding, crusting, or diagnostically uncertain may need assessment before cosmetic treatment.

Picosecond laser energy is delivered in very short pulses to affect pigment while limiting heat spread. You may notice warmth, tingling, or quick snapping sensations. The area can become red, swollen, or temporarily darker; a fine crust or peeling surface may develop as it heals.

Tell the clinic about recent sun exposure or tanning, medicines, previous reactions, and any history of slow healing or raised scars. Follow instructions about arriving without irritating products on the treatment area.

Keep the area clean and moisturised as directed. Avoid picking, scratching, scrubs, and heat exposure while the surface is sensitive. Use broad-spectrum sun protection and protective clothing because ultraviolet exposure can deepen pigment and make the result harder to judge. Let the clinician guide the timing of further sessions.

Ask for clinical advice if pain, swelling, redness, or tenderness is increasing, if blisters or spreading warmth appear, or if the area produces discharge. Arrange review for a spot that changes in shape or colour, repeatedly bleeds, or fails to heal.

Ask how the spot was assessed, what changes are expected during healing, which sunscreen and products are suitable, and how long to wait before reassessment. Check how a changing or recurrent mark will be evaluated.
