A device for collecting sebum which is secreted from the sebaceous glands of a subject includes a microporous, hydrophobic polymeric film which is opaque to light when the pores are filled with gaseous material and which is substantially translucent when the film pores are filled with sebum. The film is mounted to a substrate which includes a light absorbing area for enhancing visualization of the film pores when filled with sebum.
