Skin wrinkles are associated with changes in the rheological properties of skin tissue. In this paper, we use Optical Coherence Tomography (OCT) to visualize skin tissue at micr-scale, and Optical Coherence Straingraphy (OCSA) to visualize skin tissue rheology. In order to investigate the validity of this method, suction tests were conducted on the forearm. The OCSA method was applied to the creep recovery time after the suction was released. The epidermis was more elastic than the dermis layer with a shorter creep recovery time by time series of strain velocity distribution. Therefor rheological properties of the skin can be visualized on a micro scale and that skin mechanics can be evaluated.
