Laser removal of keloid scars
Updated: Oct 11
A keloid is an overgrowth of scar tissue extending beyond the original skin injury. A hypertrophic scar remains within the wound boundaries. Laser treatment may help selected keloids as part of an individual plan, but examination comes first: a raised scar is not necessarily a keloid.
Relevance and impact on quality of life
Keloid scars are not just an aesthetic issue. They are often accompanied by itching, pain, a feeling of tightness, and reduced skin mobility. Such scars can cause psychological discomfort, lower self-confidence, and interfere with normal social interaction. Treating keloids is therefore not only a cosmetic matter but also a medical task that directly affects a patient’s quality of life.
Features of keloid scars
A clinician considers several features when assessing a possible keloid:
Scar tissue extends beyond the original injury.
The tissue contains excess collagen.
Color may be pink, reddish or darker and can change over time.
A family tendency may be present. Keloids occur in different skin types and are more common in people with darker skin.
Common sites include earlobes, the chest, shoulders and back, although other areas can be affected.
Color and elevation alone do not confirm the diagnosis. The history of the injury, scar boundaries, pattern of growth, symptoms and previous treatment also matter.
Why are keloids harder to treat?
Keloid tissue can keep growing or grow back after treatment. An improvement in appearance does not establish that recurrence risk has gone; follow-up is part of assessing the result.
Treatment options include silicone products, injections, pressure therapy, cryotherapy and selected laser approaches. Surgery may be considered for some scars with a plan to reduce recurrence. The appropriate combination depends on the scar and the patient; not everyone needs every method. The consultation also covers which options are available.
A 2022 Cochrane review included 15 trials with 604 participants. The evidence was insufficient to confidently support or refute laser treatment for keloid and hypertrophic scars. These findings cannot justify promising a particular result. Leszczynski et al., Cochrane, 2022
Laser treatment may aim to reduce redness, symptoms or scar prominence. These goals differ from a guaranteed cure: treatment does not remove the underlying tendency to form keloids.
Modern technologies and an individualized approach
Dr Alexander Uskov assesses scar type and activity, location, thickness, color, skin condition and previous treatment when planning care. Different laser technologies and other methods may be considered according to the findings.
Vascular and fractional lasers address different features. A protocol used for a hypertrophic scar cannot automatically be applied to an active keloid. Ablative laser removal as the sole treatment is not a general solution for keloids; the clinician decides whether a combination is appropriate.
Planning a course of treatment
Care may involve repeated procedures and follow-up. Dr Alexander Uskov selects a protocol for the individual scar; several lasers or additional methods may be combined when indicated rather than used as a fixed package for everyone.
Scar age is one factor in planning. It does not by itself determine the number of sessions or justify stronger settings. Scar activity, skin response and treatment tolerance guide adjustments.
Diagnostics before starting therapy
At an in-person assessment, the clinician reviews how the scar developed, whether it is growing, symptoms and previous treatment, then examines the scar and surrounding skin. Additional investigations are selected when indicated.
Whether dermatoscopy, a Wood's lamp examination, infrared imaging or ultrasound is relevant should be discussed for the individual case. A set of tests does not guarantee a precise outcome prediction. An unusual appearance or pattern of change may require further assessment before treatment.
Risks and recovery
Device choice, settings and protective measures help manage risk but do not make treatment risk-free. Depending on the method and skin condition, adverse effects can include pain, redness, swelling, skin injury, burns, pigment changes, infection and worsening scarring.
A keloid may enlarge again even after an initial response. Before a procedure, discuss aftercare, recovery and the signs that should prompt contact with the clinic.
Realistic expectations
Possible treatment goals include reducing scar prominence, itching, tenderness or movement restriction. The degree of improvement varies; complete disappearance and freedom from recurrence cannot be promised in advance.
The photographs illustrate individual clinical cases. They do not replace an examination or predict the same result for another patient. Long-term outcomes cannot be established without the case history and follow-up dates.
Consultation and additional resources
An in-person examination is needed to choose treatment. Photographs alone cannot reliably establish scar type and activity.
Dr Alexander Uskov discusses possible methods, expected benefit, limits, risks and follow-up. The plan may involve lasers, other approaches or observation without a procedure.
Frequently asked questions
Can a keloid be completely removed?
A scar can sometimes be reduced considerably, and surgery with additional treatment may be considered in selected cases. Complete, lasting disappearance cannot be guaranteed because a keloid can regrow. Laser treatment is not a universal way to remove every keloid.
How many sessions are needed?
There is no universal session count. An estimate of 4–10 sessions may not fit your case; the number, intervals and need to continue are assessed after examination and according to the response to treatment.
What are the risks of laser treatment?
Treatment has risks even under medical supervision. Possible problems include pain, burns, pigment changes, infection, worsening scarring and keloid regrowth. The likelihood and ways to reduce risk depend on the method and individual factors.
Does it hurt?
Sensation depends on the method, treatment area and the person's sensitivity. Local anesthesia may be used for the chosen procedure; its need and type are discussed beforehand. A painless procedure or equally comfortable recovery for everyone cannot be promised.
When should I seek treatment?
Seek assessment if a scar is growing, itchy, painful or restricting movement. An early examination helps guide the plan, but it does not mean laser treatment should start immediately or that earlier treatment always gives a more durable result.
