At evaluation timepoints, the Goodman and Baron grading scale demonstrated significant improvement, with statistically significant differences ( P < 0.05).

Common side effects included pain (93%), mild swelling (41%) and erythema (34%), all of which were transient.

The baseline severity of scars (Goodman and Baron) and the presence of rolling scars significantly influenced treatment efficacy ( P < 0.05).
