The Publisher and Editor of International Journal of Nanomedicine wish to retract the published article. It came to the journals attention that several images shown in Figure 16 of the article appeared to be duplicated. Specifically,

• The three panels in the top row, Control group (without inducing acne), appears to show duplicated versions of the same image which have been frame shifted and had their size altered.
• The left and right panels of the row, Acne induced group 1, appear to show duplicated versions of the same image with the left panel being an enlarged version of the image on the right.
• The middle panel of the row, Acne induced group 1, and the three panels of the row, Acne induced group 2, appear to be duplicated versions of the same image which have been frame shifted and undergone size alterations.
• The left and middle panels of the row, Rabbit ear pinna after treatment with cream formulation for 14 days, appear to show duplicated regions of the same image which have been rotated.
• The left panel of the row, Rabbit ear pinna after treatment with cream formulation for 14 days, appears to be duplicated with the image shown in the right panel of the bottom row, Rabbit ear pinna after treatment with niosomal gel formulation for 14 days, but this image has been rotated.
• The left and middle panels of the bottom row, Rabbit ear pinna after treatment with niosomal gel formulation for 14 days, appear to show the same duplicated image with have been rotated and had their size altered.

The authors could not provide a satisfactory explanation for the alleged image manipulation nor could they provide copies of the original images.
