Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Stria alba (aka white or atrophic stretch marks) is a very common dermatologic condition that causes major psychological distress to those afflicted. We study the effect of low level light therapy using infra red diode 808/915 nm laser in comparison to fractional CO2 alone and combined both therapies.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

All patients will be subjected to the following:

* Written informed consent.
* Detailed history and clinical evaluation.

The treated areas will be photographed (in standardized settings of light and position) and measured in order to allow comparison and assessment of striae improvement following treatment.

Patients will be allocated according to randomization into one of 3 arms:

Arm A will be treated by fractional CO2 laser. Arm B will be treated by low level light therapy (LLLT). Arm C will be treated with a combination of fractional CO2 laser and LLLT.

Digital photographs will be taken for each patient, at the baseline and 1 and 3 months after last session and the width of the widest striae in each patient will be measured at the same time. Patients will be assessed before and after treatment by one unblinded and 2 blinded investigators to measure the clinical improvement on a 4-point scale by comparing the photographs. The criteria for evaluation using a quartile grading scale will be as follows; 0=no improvement, 1=mild improvement (\<25%), 2=moderate improvement (26% - 50%), 3=good improvement (51% -75%), 4=excellent improvement (\>76%).

In addition, a patient satisfaction score will be rated using the following scale; 0=not satisfied, 1=slightly satisfied, 2= satisfied, 3=very satisfied, 4=extremely satisfied as well as patients' satisfaction questionnaire (Yang and Lee; 2011).

Low level light therapy (LLLT)

Low level light therapy using 808/915 nm infra red diode laser

Group Type ACTIVE_COMPARATOR

Low level light therapy

Intervention Type DEVICE

Patients will be offered 8 sessions of photobiomodulation using HPL Pagani Diode 808/915nm LLLT 3.2W (Fimad Elettromedicali SRL®, Catanzaro, Italy) with the parameters adjusted individually according to the surface area to be treated. Optimum dose is 10 joules/cubic centimeters. The patients will take 2 to3 sessions / week.

Fractional CO2

Fractional carbon dioxide laser 10600 nm

Group Type ACTIVE_COMPARATOR

Fractional CO2

Intervention Type DEVICE

Patients will be offered 2 sessions of fractional carbon dioxide laser on a 4 weeks interval. Topical anesthesia with pridocaine cream will be applied under occlusion for 30 - 60 minutes before the session.

* Please update to the proper apparatus and parameters DEXA SmartXide DOT Fractional CO2 laser system 10600 nm (DEKA®, Florence, Italy) will be used with the following parameters adjusted individually to patients': power of 15-20 W, dwell time of 500-800 μs, spacing of 200-500 μm, and stack 2.

Combined fractional CO2 and LLLT

Combined fractional CO2 laser and low level light therapy

Group Type ACTIVE_COMPARATOR

Combined fractional CO2 laser and low level light therapy

Intervention Type DEVICE

Combined treatment of both modalities (fractionational CO2 laser and low level light therapy). Please describe more....
