Abstract
It is intended to provide a method whereby the skin conditions (for example, loss in the skin elasticity, wrinkle formation possibility, insufficient tightness in dermal collagen fiber bundles, or the like) can be exactly and conveniently assessed. It is also intended to provide a method whereby the wrinkle-improvement effect of a test substance can be exactly and conveniently evaluated. The skin conditions are assessed by using the expression amount of an adhesion factor in skin cells as an indication. The wrinkle reducing effect of a test substance is evaluated by using the expression amount of an adhesion factor in skin cells in the presence of the test substance as an indication.
