Are non-ablative fractional lasers safe & effective on acne scars?

Posted by Kikki Walther on Nov 6, 2018 9:23:37 AM

Many methods have been proposed for the treatment of acne scars, including fractional and non-ablative fractional laser treatments. 


A literature search1 conducted in 2016 concludes fractional lasers as a favorable treatment option for treating acne,  acne scars, scars, striae and skin rejuvenation*.


New Case Study: Non-Ablative Fractional Laser Treatment on East-Asian Skin

A new retrospective case study2 published at EADV in Paris, September 2018 by Dr. Rebecca WY Wong and Dr. Sai Siong Wong provides new results on the safety and efficacy of Frax 1550 on East-Asian skin.


Study on fractional non-ablative treatment of atrophic acne scars


20 of 21 East-Asian patients experienced improvements of their facial atropic acne scars after 3 full-face treatments with the non-ablative fractional laser Frax 1550.


The non-ablative fractional 1550nm laser is safe and provides clinical efficacy in the treatment of facial atrophic acne scars in East-Asian patients with minimal side effects and downtime. Complications are
predictable and thus avoidable with the appropriate laser parameters for treatment.


Positive "Side Effects"   

As a positive "side effect" to their laser treatment, the patients also noted pore reduction, textural improvement, diminished acne erythema and overall a more uniform pigmentation.

"The Frax 1550 is a good choice for treating acne scars in Asian skin. There is minimal downtime and post-inflammatory hyperpigmentation compared to ablative lasers for atropic acne scars"
Dr. Rebecca WY Wong and Dr. Sai Siong Wong
