Abstract
|
|
|
|
The objective of this study was to investigate the feasibility of applying the Intense Pulsed Light (IPL) as a tool to enhance the skin absorption of arbutin, a well-known skin-whitening agent. Arbutin solution or skin formulation was applied on the back of hairless mouse skin in vivo after IPL treatment, and then the skin deposition of arbutin was determined by HPLC. IPL treatment significantly increased the amount of arbutin in the skin after 6 hours when arbutin solution was applied 20 times. IPL also enhanced the skin deposition of arbutin when arbutin formulation was applied, although it was not significantly different. Significant increase of surface skin temperature was observed by IPL treatment, which might be a mechanism of the enhanced skin absorption of arbutin. These results suggest the feasibility of using IPL as a tool to increase the skin absorption of whitening agents, although further research needs to be conducted to understand its exact mechanism.
