Treating Acne Scars in Fitzpatrick Skin Types I-VI Using a Novel 1550 nm Non-Ablative Resurfacing Laser With Focal Point Technology.

BACKGROUND

Acne scars have traditionally been treated with non-ablative fractional resurfacing lasers. Traditional 1550 nm lasers can be limited in energy delivery, skin cooling, and safety across all skin types. A new-generation 1550 nm non-ablative resurfacing laser was recently developed, employing conical beams for high energy delivery through Focal Point Technology.

OBJECTIVE

To evaluate the utility of a 1550 nm non-ablative resurfacing laser using Focal Point Technology to improve acne scars in Fitzpatrick skin types I-VI.

METHODS AND MATERIALS: A prospective, multi-center clinical study investigated this novel resurfacing laser using 1-6 treatments.

RESULTS

Forty-seven subjects with Fitzpatrick skin types I-VI were enrolled and treated. Mean age was 40.2 years, and 59.6% were women. Based on GAIS, 78.0% were rated as improved, with none worsening. Two of three blinded reviewers correctly identified photographs for 92.7% of subjects. Significant improvement in blinded ECCA score was observed (85.6 vs. 55.3; p < 0.0001), with 90.2% achieving at least a 15-point improvement. Treatments were well tolerated.

CONCLUSION

This new-generation 1550 nm non-ablative laser using Focal Point Technology with high energy delivery is safe and effective for acne scar treatment in all Fitzpatrick skin types. Its conical beams and cooling system significantly reduce hyperpigmentation risk in darker skin types.
