This study looked at the efficacy and safety of IPL and Erbium fractional laser for patients with striae gravidarum (SG).Patients and Methods: All 60 patients with SG were successfully enrolled in the study. IPL treatment was followed by Erbium fractional laser (wavelength 2940 nm) treatment at 4-week intervals for a total of three treatments. SG elasticity was assessed with a SEM575 custom instrument and patients were scored for SG span with an Antera 3D multifunctional skin imaging analyzer. A 3D skin impact system was used to assess patients’ epidermal thickness. A visual analog scale (VAS) was used to assess patients’ pain scores during the treatment period. Improvement in stretch marks was assessed with the Global Aesthetic Improvement Scale (GAIS). The occurrence of adverse events was recorded at a follow-up of 3 months. Patient satisfaction with the outcome of the treatment was also recorded.Results: Area of stretch marks decreased from 7.89 ± 0.49 cm2 pre-treatment to 4.94 ± 1.16 cm2 post-treatment (P < 0.001). The grayness values and atrophy of stretch marks were reduced after treatment. Furthermore, skin elasticity and thickness at the lesions of patients increased significantly after the treatment (P < 0.001), while the width of the stretch marks significantly decreased (P < 0.001). The VAS score was 5.45 ± 1.31, the incidence of adverse events was 25%, and patient satisfaction with the efficacy was 96.67%.Conclusion: IPL combined with Erbium fractional laser improves the area and atrophy of SG, lightens the color, and increases the elasticity and thickness of the skin, with high treatment safety and remarkable clinical results.Keywords: IPL, striae gravidarum, erbium fractional laser
