Abstract
A sampling device and method for collection of sebum secreted by a person for determination of the person's skin oil characteristics includes a sampling element having a backing member of liquid impervious material. An absorbent material is disposed upon the backing member for absorbing sebum secreted by a person's skin, the absorbent material defining an absorption surface. A device is provided for disposing the absorption surface in contact with a region of the person's skin during the predetermined sampling period. The element is sealed within a liquid impervious pouch formed at least in part of the backing member during transport of the collected sebum to a site for measurement. A method for collection of sebum for selection of facial cosmetics of complementary formula is also described, including the step of providing a line of facial cosmetics formulated with oil and the like present at stepped levels preselected to complement a range of sebum production.
