They will be filling out two OSSAS surveys (one for each side of the face) at the second and third sessions. The OSSAS survey includes subjective assessment of four components of oily skin: visual, blotting, tactile, and sensation.

High-resolution digital photographs of the facial skin with the use of photography and facial analysis instrumentation will be taken at baseline and at each visit to document facial appearance and for image analysis of shine level. Sebum of the left and right cheeks will be measured by a sebumeter to correlate to the oily appearance noted on the high resolution facial photographs.
