Caesarean Scar Revision With the UltraPulse

Ten (10) adult female subjects that had a caesarean surgery performed.Study will be conducted in 1 site.

Each subject will receive three treatments on one area that was randomly chosen. The other area will be left untreated and will serve as a control.

The objective is to Evaluate the clinical impact of UltraPulse fractional carbon dioxide laser treatment on the appearance of a Caesarean Scar (CS) as compared to a similar untreated scar side.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Scar Evaluation	VSS , POSAS, Appearance assessment-Evaluation of the scar by blinded investigator.	3 month following the 3rd treatment.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Scar Evaluation.	VSS assessment -Evaluation of the scar by blinded investigator.	At base line , at the 3rd treatment and at the 1, 3 and 6 months follow-up
POSAS assessment	POSAS assessment by blinded Investigator and subject	At base line , at the 3rd treatment and at the 1, 3 and 6 months follow-up
Scar Thickness and Uniformity	A High Definition Ultrasound (US) device will be used to generate a high resolution image of the skin layers of the treated and non-treated scar in order to measure and compare changes in scar thickness and uniformity.	At base line, at the 3rd treatment and at the 1, 3 and 6 months follow-up
Scar color	Colorimeter will be used for color measurement.	At base line, at the 3rd treatment and at the 1, 3 and 6 months follow-up.
Histochemical Changes in scar tissue	Histochemical analysis of scar tissue with different staining for analysis of changes following treatment: H&E staining and histology for collagen arrangement, epidermal rete ridges and measurement of scar depth; Collagen type I and III staining; Elastin staining; Immunohistochemistry for TGF-beta 1, 2, 3 and MMPs	Immediately before the 2nd, and 3rd treatment
Subject's satisfaction	Subject's satisfaction of the treatment using a Satisfaction Scale as follows: None; Slight; Moderate; Good; Very Good.	At the 3rd treatment and at the 1, 3 and 6 month follow-up
