Laser scar treatments employ specific lasers to target pigment, vascularity, or texture, stimulating collagen and reducing contrast between scar and normal skin. Multiple sessions and tailored approaches - often combined with other therapies - are typical. Risks include pigment changes and, rarely, scarring; outcomes depend on scar type and skin tone.
How laser scar treatment works
Laser scar treatment uses focused light to change scar pigment, remodel collagen, or reduce scar blood supply so scars become less visible. Different lasers target different components of a scar: pigment-focused lasers (Q-switched and picosecond) break up excess melanin; vascular lasers (pulsed dye) reduce redness; and ablative or fractional lasers (CO2, Er:YAG, fractional non-ablative devices) create controlled micro-injury that stimulates collagen remodeling and surface renewal.
Who benefits and what to expect
Lasers can improve many scar types - atrophic (pitted) acne scars, hypertrophic scars, and some surgical scars - but outcomes vary. Treatment aims to reduce contrast with surrounding skin and soften texture; complete removal is rare. Most patients need a series of treatments spaced weeks apart. Downtime ranges from minimal redness to several days of crusting and swelling depending on the device.
Skin tone matters. Darker skin (higher Fitzpatrick types) has a higher risk of pigment changes after treatment, so providers often choose gentler settings or alternative approaches for these patients.
Common lasers and their roles
- Fractional CO2 and Er:YAG: Ablative or fractional resurfacing for deep texture improvement and collagen stimulation.
- Non-ablative fractional lasers: Less downtime, gradual collagen remodeling for mild-to-moderate scars.
- Pulsed dye laser (PDL): Treats redness and reduces scar blood vessels, useful for hypertrophic scars and keloids in some cases.
- Q-switched and picosecond lasers: Target pigment in post-inflammatory hyperpigmentation or tattooed scars.
Risks and recovery
Expected short-term effects include redness, swelling, and peeling. Possible complications include prolonged pigment changes, infection, or new scarring - risks that increase with aggressive settings or inexperienced operators. Proper pre- and post-treatment care (sun protection, wound care, and following provider instructions) reduces complications.
Choosing a provider
Seek a board-certified dermatologist or plastic surgeon experienced in lasers and scar management. A safe plan includes an in-person evaluation, discussion of realistic goals, explanation of alternatives, and a treatment schedule tailored to your scar type and skin tone.
Bottom line
Laser scar treatments are established tools that can significantly reduce scar visibility for many people. They work best as part of a tailored plan that considers scar type, skin tone, and realistic expectations. Discuss benefits, risks, downtime, and costs with a qualified provider before proceeding.
