Method and apparatus for the determination of abnormal skin dryness

摘要

A method for the determination of abnormal skin dryness includes providing a reaction support ( 2 ), in particular of textile, which is impregnated with a 3.15- to 25-weight percent cobalt(II) chloride solution and then dried until the cobalt(II) chloride has a blue color. The reaction support ( 2 ) is applied onto one side of a planar base element ( 1 ) made of a flexible material. The reaction support ( 2 ) is covered with a protective material ( 3 ) that is impermeable to air and moisture. The protective material ( 3 ) is removed immediately before the determination of skin dryness. The reaction support ( 2 ) is placed onto a skin area and secured, and is removed from the skin again after a defined time interval, with a color shift of the reaction support to red indicating a normal skin dryness.
