There were no previously published experiences of surface irregularity by the use of three-dimensionally reconstructed digital grids in wrinkles. Therefore, we presented a simple setup that uses objective measurement of the surface irregularity of facial wrinkles and applies this to the comparison of surface irregularity between three different facial expressions. Limitations include the system's restricted field of view, which requires multiple image acquisition for areas of interest outside the field of view, and the lack of an automated region of interest definition and a calculation for surface irregularity. The presented approach incorporated the advantage of using a rapid and noncontact technique, and the resultant data contained all characteristics relevant for wrinkle assessment.

Viewpoints, pertaining to issues of general interest, are welcome, even if they are not related to items previously published. Viewpoints may present unique techniques, brief technology updates, technical notes, and so on. Viewpoints will be published on a space-available basis because they are typically less timesensitive than Letters and other types of articles. Please note the following criteria:
* Text—maximum of 500 words (not including references)
* References—maximum of five
* Authors—no more than five
* Figures/Tables—no more than two figures and/or one table
Authors will be listed in the order in which they appear in the submission. Viewpoints should be submitted electronically via PRS' enkwell, at www.editorialmanager.com/prs/. We strongly encourage authors to submit figures in color.
We reserve the right to edit Viewpoints to meet requirements of space and format. Any financial interests relevant to the content must be disclosed. Submission of a Viewpoint constitutes permission for the American Society of Plastic Surgeons and its licensees and assignees to publish it in the Journal and in any other form or medium.
The views, opinions, and conclusions expressed in the Viewpoints represent the personal opinions of the individual writers and not those of the publisher, the Editorial Board, or the sponsors of the Journal. Any stated views, opinions, and conclusions do not reflect the policy of any of the sponsoring organizations or of the institutions with which the writer is affiliated, and the publisher, the Editorial Board, and the sponsoring organizations assume no responsibility for the content of such correspondence.
