Background and Objectives: Essential oils are a complementary treatment and can play an important role in scar care. The aim of this study was to evaluate and compare the efficacy of a new essential oil (regeneration oil) with a control group on scar quality in healed split-thickness skin graft donor sites. Materials and Methods: A single-center blinded randomized controlled study was performed on 30 patients with healed split-thickness skin graft donor site. The patients were randomly allocated into blended regeneration oil (n= 14) and pure almond oil (n= 16) groups. Application of the assigned oil occurred twice a day for 6 months. Scarring (Patient and Observer Scar Assessment Scale), itching (ITCH Assessment Scale) and scar discoloration (colorimetry) of the donor sites were assessed after 1, 3 and 6 months. Results: We found no statistically significant differences between the groups in any applied parameter. We observed comparable outcomes (scar quality, itchiness, colorit) in healed split-thickness skin graft donor sites for both oils. Conclusions: Regeneration oil and control oil presented comparable results regarding scar quality, itchiness and colorit in healed split-thickness skin graft donor sites after 6 months of application. Both oils are suitable for skin/scar care in split-thickness skin graft donor sites.
