Trial Summary

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. However, if you are using certain topical or systemic retinoids, corticosteroids, or other prescription topical medications on the area of interest, you may need to stop as these are part of the exclusion criteria.

What data supports the effectiveness of the DFG Laser vs CO2 Laser treatment for pain and wound healing?

Fractional CO2 lasers have been shown to effectively treat skin issues like scars and photoaging with fewer side effects and quicker recovery compared to traditional methods. This suggests that similar laser treatments, like the DFG Laser, might also be effective for pain and wound healing.12345

How does the DFG Laser treatment differ from other treatments for pain and wound healing?

The DFG Laser treatment, which includes fractional CO2 lasers, is unique because it combines fractional photothermolysis (a method that targets small areas of skin) with an ablative wavelength, allowing for effective treatment of scars and skin damage with shorter recovery times and fewer side effects compared to traditional CO2 laser treatments.12356

What is the purpose of this trial?

This research study aims assess whether the Difference Frequency Generation (DFG) laser could be a better alternative to the CO2 laser in terms of reduced side effects and patient downtime.

Findings from Research

Fractionated CO(2) lasers are effective for skin resurfacing, particularly in treating facial photoaging and scars.
These lasers offer a better safety and recovery profile compared to traditional CO(2) laser treatments, making them a preferable option for patients.
Fractional CO(2) laser resurfacing.Carniol, PJ., Harirchian, S., Kelly, E.[2017]
A retrospective study of 490 fractional CO2 laser treatments in 374 patients showed that this method has a low incidence of adverse events (13.6%), making it a safe option for treating skin issues like wrinkles and scars.
The most common side effects included acneiform eruptions and herpes simplex outbreaks, but there were no reports of scarring or hypopigmentation, indicating a favorable safety profile compared to traditional laser treatments.

Ablative carbon dioxide fractional laser treatment applied 2 to 3 weeks after thyroid surgery significantly improved the appearance of scars, as indicated by lower Vancouver Scar Scale scores in 23 women.
The treatment was found to be both effective and safe, with 12 out of 23 participants showing over 51% clinical improvement in scar appearance three months post-treatment.
