Acne Scar Laser Treatment: Options, Safety and Recovery

Acne scar laser treatment uses controlled light energy to remodel skin and soften the appearance of uneven scars.

Laser treatment delivers focused light energy to selected skin layers. Depending on the device and settings, it may create microscopic treatment zones, remove a thin surface layer, or heat deeper tissue to encourage remodelling. The aim is to make depressed or uneven acne scars less noticeable; it does not erase the history of acne or restore skin in a single visit.

People may feel heat, prickling, snapping, or stinging during treatment. A topical numbing product, cooling, or other comfort measures may be used depending on the laser. Skin can feel sunburned or tight afterward. Tell the clinician about low pain tolerance, cold sores, or medicines that affect healing.

Laser treatment can be appropriate when the device, energy level, and timing are matched to your skin and scar type. Temporary redness, swelling, peeling, or darkening can occur. Burns, infection, prolonged colour change, or worsening texture are less common but possible, especially if aftercare is poor or the settings are unsuitable.

Changes from collagen remodelling develop gradually and can remain while the treated scar tissue stays remodelled. New acne, ageing, sun exposure, and the original depth of the scar affect the visible result. Several sessions or combination treatment may be discussed, and improvement is not the same as complete removal.

The best approach depends on scar depth, edges, skin tone, active acne, and whether scars are depressed or raised. Fractional devices treat patterned microscopic areas, while a CO2 laser can deliver stronger resurfacing. Your clinician should explain why a specific device and setting fits your skin.

It may be considered for stable, depressed acne scars when texture remains a concern after active breakouts are controlled. People with [Acne Scars](/conditions/acne-scars/) or [Atrophic Scars](/conditions/atrophic-scars/) need an assessment because rolling, boxcar, and narrow deep scars may respond differently. Active infection, uncontrolled acne, recent tanning, or a history of difficult healing can change the plan.

The clinician maps the scar pattern, reviews medicines and healing history, cleanses the skin, and applies comfort measures when needed. Protective eyewear is used. The laser is passed over selected areas using planned settings. Afterward, the skin is cooled or dressed and you receive instructions for cleansing, moisturising, and sun protection.

Recovery varies with the laser intensity. Mild treatment may cause redness and roughness, while resurfacing can cause more peeling, tenderness, and visible healing. Keep the area clean, moisturised, and protected from sunlight as instructed. Do not pick peeling skin or restart irritating products before the skin has recovered.

Risks include prolonged redness, swelling, infection, burns, acne or cold-sore flare, darker or lighter patches, and changes in texture. Scars can heal unpredictably. Contact the treating clinic promptly for increasing pain, spreading redness, pus, blistering, or a delayed healing response.

Alternatives include microneedling, chemical reconstruction, fillers, or [Subcision](/treatments/surgical-dermatology/subcision/) for selected depressed scars. Treating active acne may involve [Isotretinoin Treatment](/treatments/medical-dermatology/isotretinoin-therapy/), although timing around procedures needs medical planning. Read about [CO2 Laser](/technology/co2-laser/) and [Fractional Laser](/technology/fractional-laser/) when comparing device approaches.

Look for a qualified clinician who diagnoses the scar type, checks for active acne and pigment-change risk, explains the selected device, and shows how recovery will be managed. Ask what preparation is needed, which symptoms require contact, and whether combination treatment is more suitable than laser alone.
