Abstract

Effect of rubbing application on the skin permeation of a hydrophilic drug caffeine (CAF) and lipophilic drug rhododendrol (RD) from lotion and cream were investigated. Skin permeation of CAF was markedly increased by rubbing action independent of the formulation type. In addition, the skin penetration-enhancement effect was affected by the rubbing direction: rubbing application against the direction of hair growth showed the highest permeation compared with rubbing applications along the direction of hair growth and in a circular pattern on the skin. On the other hand, no enhancement effect was observed by the rubbing actions on the skin permeation of RD, regardless of formulation type. Change in the infundibula orifice size of hair follicles by the rubbing and following skin stretching may be related to the higher skin permeation for CAF. In contrast, high RD distribution into the stratum corneum may be a reason why no enhancement effect was observed by the rubbing action. These results can be helpful to predict safety and effectiveness of topically applied formulations.
