Purpose: Acne scarring represents a common problem that negatively impacts patients’ quality of life. Different types of treatments are currently available for this dermatological condition. This study evaluates the efficacy of a new 675-nm laser source system on acne scars with the use of established parameters that guarantee minimum pain and the absence of side effects such as hyperpigmentation, hypopigmentation, and blistering. Methods: A total of 24 subjects (all women, aged 21–42 years), with Fitzpatrick skin types I–IV and facial acne scars, were treated with three sessions of a 675-nm laser system. Efficacy of treatment was evaluated using the Goodman and Baron’s quantitative grading scale before and 3 months after the last treatment. Results: All 24 patients treated with this new 675-nm laser had significant improvement of acne scars according to Goodman and Baron’s Quantitative Global Acne Scarring Grading System. No side effect has been observed except some minor erythematous reactions in three patients. Conclusion: The 675-nm laser system we used appears to be effective and well-tolerated in patients with acne scars, and it involves a simple post-treatment management.

Abstract

Purpose: Acne scarring represents a common problem that negatively impacts patients’ quality of life. Different types of treatments are currently available for this dermatological condition. This study evaluates the efficacy of a new 675-nm laser source system on acne scars with the use of established parameters that guarantee minimum pain and the absence of side effects such as hyperpigmentation, hypopigmentation, and blistering. Methods: A total of 24 subjects (all women, aged 21–42 years), with Fitzpatrick skin types I–IV and facial acne scars, were treated with three sessions of a 675-nm laser system. Efficacy of treatment was evaluated using the Goodman and Baron’s quantitative grading scale before and 3 months after the last treatment. Results: All 24 patients treated with this new 675-nm laser had significant improvement of acne scars according to Goodman and Baron’s Quantitative Global Acne Scarring Grading System. No side effect has been observed except some minor erythematous reactions in three patients. Conclusion: The 675-nm laser system we used appears to be effective and well-tolerated in patients with acne scars, and it involves a simple post-treatment management.
