Skin Research and Technology | 2018

Visualization of viscoelastic behavior in skin equivalent using optical coherence tomography-based straingraphy

Yusuke Hara; Y. Ogura; Toyonobu Yamashita; Daisuke Furukawa; Souichi Saeki

The relationships between the skin components and these mechanical roles are still unclear. To clarify these relationships, we investigated spatial mapping of the mechanical behavior of cultured skin equivalents (SEs) using optical coherence tomography (OCT)‐based straingraphy.

Novel Skin Evaluation Methods Using Cutting-edge Optical Techniques

Toyonobu Yamashita; Mariko Egawa; Yusuke Hara

The acquisition of objective skin information by analytical techniques is essential for evaluation of the ef fects of cosmetics and pharmaceuticals to the skin. In addition, analytical approaches that target not only the skin surface, but also those that specifically evaluate skin layer features and skin constituents are long-awaited. The progress of non-invasive optical technologies in recent years enables us acquisition of the skin structural information at a molecular level as well as the evaluation of skin physical properties. In this ar ticle, we present our novel skin evaluation methods developed using optical techniques.
