OBJECTIVE: The Sebumeter is widely used in both cosmetic and medical research, for measuring changes in sebum levels on skin.
It is commonly reported that the units correlated to a mass of sebum on the skin in lg cm 2; however, validation for this has not been published. Also, its use for assessing the presence of other oily materials which are widely utilized in topical skincare products on skin has not been widely discussed. Determining a calibration scale and whether the response of the device is linear with the level of oils present enables quantification of the output of the device, and would validate the device for claims substantiation.
