A research team with LG Household & Health Care in Seoul, Korea, have developed and validated a novel facial glycation imaging system (FGIS) for assessing the skin glycation index (SGI) in facial skin.

They believe the device will be a valuable tool for studies on skin aging and anti-glycation cosmetic products.

The FGIS includes illumination (white light-emitting diode, ultraviolet light-emitting diode) and image acquisition modules to capture face images. An image analysis algorithm was then used to calculate advanced glycation end product (AGE)–related autofluo­rescence and total skin reflectance and obtain the SGI.

To validate the device, they performed a study that included 36 healthy Korean women, which was published in the Journal of Cosmetic Dermatology. The women were between 20-59 years (five subjects, aged 20-29 years; eight, 30-39 years; 13, 40-49 years; and 10, 50-59 years.)

The illumination module of the device features white light-emitting diode (LED) and UV LED light sources; a 365 nm short pass filter (Ruisen Optics, CN) was mounted in front of the UV LED light sources to specifically excite skin AGEs, such as pentosidine.
