There is provided a screening method which can select a photoaging-preventing or improving agent or a wrinkle-preventing or improving agent with efficiency and reliability. The screening method for a photoaging- or wrinkle-preventing or improving agent selects, as a candidate, a substance inhibiting the expression of keratin 6 and/or keratin 16 genes or keratin 6 and/or keratin 16 proteins in a skin tissue or cell.

Method for screening an agent for preventing or ameliorating wrinkles

Cosmetics containing the following components (A) and (B): (A) an oil-absorbing powder having a squalane-absorbing ability of 1 ml/g or more; and (B) a compound having an affinity for component (A) lower than that of sebum, and having an ability to absorb the sebum and release component (B) in exchange for the sebum when the cosmetic is applied onto the skin. These cosmetics can adequately absorb the sebum and thus exhibit excellent effects of relieving or preventing oiliness of the skin and worsening in makeup. By selecting an appropriate compound to be released in exchange for the absorbed sebum, a substance capable of improving the skin qualities such as moistness, tightness, and tension can be allowed to penetrate into the skin. Moreover, a bodily feeling of the removal of the sebum can be imparted to users thereby.
