摘要:
The invention provides a non-contact process for measuring amount of sebum or oil on skin or other substrate. Process is preferably done in vivo because of ability to measure formation of sebum/oil on skin in real time.
摘要:
The invention provides a non-contact (non-invasive) method for measuring quantity of sebum oil on skin or other substrate. The method includes applying fluorescent lipophilic dye to the substrate site of interest, illuminating the site at the excitation wavelength of the dye, and collecting fluorescent emission of desired wavelength of the dye. Because the measurements are truly non-contact, they can be made in real time on the same sites for any desired length of time.
