Striae distensae treatment: evaluating laser efficacy and safety.

BACKGROUND

Striae distensae (SD) are common skin lesions that are difficult to treat and affect quality of life. Laser and light are emerging non-invasive therapies that have proven successful in treating SD. Recently, hybrid laser devices offering simultaneous fractional ablative and non-ablative laser treatment have been reported to benefit various skin conditions.

OBJECTIVE

To evaluate the improvement of SD treated with a hybrid laser system and to analyze associations with patient characteristics.

METHODS

We performed a retrospective study in which 28 adults with SD were treated with a hybrid laser device. Efficacy was evaluated by the assessment of aesthetic improvement by the Global Aesthetic Improvement Scale (GAIS) of 1-10 and by patients' satisfaction using a scale of 0-10 satisfaction scale. Pain and adverse events were monitored. Statistical analysis was used to examine the potential impact of various factors on treatment outcomes.

RESULTS

The mean GAIS score was 7.36 ± 1.06 with a positive correlation with patient satisfaction (r = 0.685) and a weak negative correlation with patient age (r = -0.0057). Skin type and body area did not show significant associations with GAIS scores (P > 0.05 for both). No adverse events were observed.

CONCLUSION

This study demonstrates the potential of the hybrid laser system as a safe and effective method to achieve satisfactory aesthetic results with minimal downtime, making it a promising treatment approach for SD. Treatment outcomes were independent of patient characteristics, further supporting its widespread use.
