Detailed Description

The study involves the application of ascorbic acid, hyaluronic acid, and sodium DNA in preparation for their use following the administration of a fractional CO2 laser treatment. Participants will attend a total of four sessions. During the initial session, participants will complete and sign a consent form, baseline photographs will be captured for documentation purposes, and an initial assessment will be conducted using the SASSQ. At the second session, the fractional CO2 laser will be applied, followed by the application of the topical medication to the facial area. During the third and fourth sessions, scheduled one week and four weeks post-treatment, respectively, the facial dermal effects will be objectively evaluated using the SASSQ scale, and any adverse effects will be assessed and documented through photographs.

To facilitate the analysis and comparison of variables, an analysis of variance will be conducted utilizing the ANOVA test for repeated measures. The IBM SPSS Statistics software, version 29.0, will be employed for this purpose. A p-value of less than 0.05 will be regarded as statistically significant.
