The 2910-nm Fiber Laser Is Safe and Effective for Improving Acne Scarring

Area of Science:

• Dermatology
• Laser Technology
• Aesthetic Medicine

Background:

• Acne scarring results from inflammation altering dermal collagen, leading to depressed scars.
• Lasers are utilized for skin remodeling to enhance texture and appearance of acne scars.
• A new 2910 nm erbium-doped, fluoride glass, fiber laser offers a unique treatment modality with low-energy pulses.

Purpose of the Study:

• To investigate the efficacy and safety of a novel 2910 nm fiber laser for treating acne scars.
• To evaluate the improvement in acne scar appearance using objective and subjective measures.

Main Methods:

• Fourteen subjects with rolling and/or boxcar acne scars received three treatments with the 2910 nm fiber laser.
• Digital images were captured pre-treatment and at 1- and 3-month follow-ups for blinded evaluation.
• Subject and physician Global Aesthetic Improvement Scale (GAIS) assessments were used to evaluate treatment effect.

Main Results:

• Blinded image analysis showed a mean improvement of 47.3% in scar appearance 3 months post-treatment.
• Both subjects and the treating physician reported improvement via GAIS scores.
• Observed side effects included mild erythema, edema, and pinpoint bleeding.

Conclusions:

• The 2910 nm erbium-doped, fluoride glass, fiber laser is a safe and effective treatment for improving acne scar appearance.
• This novel laser technology presents a promising option for acne scar revision.
