Background: This study aimed to evaluate the efficacy and safety of a topical antioxidant cream containing tocotrienol after 1064-nm picosecond neodymium-doped yttrium aluminum garnet (Nd:YAG) laser treatment for environment-induced skin pigmentation.
Methods: A split-face study was conducted between December 2020 and March 2021 in 26 patients (25 women and one man) who were treated with a 1064-nm picosecond Nd:YAG laser. On the right side of the face, an antioxidant cream containing tocotrienol was applied after picosecond laser treatment, and on the left side, only picosecond laser treatment was performed. We compared the right and left sides of the face at 4 weeks after laser treatment using an automatic skin analysis device to investigate skin pigmentation. The melasma severity scores of the two sides were evaluated before and 4 weeks after picosecond laser treatment.
Results: The skin pigmentation score showed a significant difference between pretreatment and 4 weeks after picosecond laser treatment on both sides of the face (P<0.001), and there was a significant difference in skin pigmentation score improvement between the right and left sides (P<0.001). The melasma severity score showed a significant difference on the right side between pretreatment and 4 weeks after laser treatment (P<0.001), but there was no significant change on the left side (P>0.05).
Conclusions: Our results show that, for the treatment of environment-induced skin pigmentation, the application of a tocotrienol-containing antioxidant cream after 1064-nm picosecond laser treatment can provide good results without any complications.
