Wichtige Hinweise

What’s already known about this topic?

• Keloid scars have a higher predilection for younger, ethnic skin.
• Keloid scars can be caused by a multitude of mechanisms, including injury, acne, surgical trauma, piercings and burns.
• Existing treatments for keloid scars include corticosteroid injections, silicone sheeting, cryotherapy, surgical excision, 5-fluorouracil and interferon alfa-2b injections, radiotherapy.

What does this study add?

• We have comprehensively reviewed and summarised contemporary literature relating to the use of light-, laser- and energy-based devices for treatment of keloid scars and quantified the evidence according to the strength of recommendation taxonomy criteria.
• Although initial findings are promising for multiple subcategories of lasers, lights and fractional radiofrequency, current evidence comprises multiple small studies and with few randomised trials
• The use of lasers in keloids is a relatively new concept, as either monotherapy or an adjunct to medical therapies. Future use of laser-assisted delivery to treat keloid scars has potential.


Keloid scars are common and have a predilection for young, ethnic skin often with a family history. Keloids can be painful and pruritic and cause significant emotional distress when particularly visible or prominent. In this article, we review the evidence underlying the use of laser- and energy-based devices for treatment of keloid scars, either as monotherapy or in conjunction with other therapies such as corticosteroids, surgery and silicone gel in the treatment of keloid scars.
