“…On the contrary, Koetsier et al found a small, non-signi cant gender difference in certain sub-populations within current smokers with women having a higher SAF [12]. Furthermore, the mean value of SAF for the healthy group in our study was 2.56, that in comparison to the results published by Yue et al had better outcomes in the reference values given for the Chinese population [30].…”

Background: Type-2 diabetes (T2D) has been associated with increased endogenous formation of advanced glycation end products (AGEs). Their accumulation in different tissues including articular collagen, skeletal and smooth vascular muscles, or glomerular basement membranes in T2D patients have been implicated. Objective: To assess the potential association of T2D in skin ageing associated with AGEs in Chinese population.Methods: A multicentre study was conducted in Chinese population of 560 subjects aged between 50 and 70 years who were evenly assigned in two groups of 280 each, paired by health status (healthy/diabetic), gender, and age group well balanced for hormonal replacement therapy/menopausal status, body mass index (BMI), smoking status and skin characteristics. Skin conditions were examined by a dermatologist and skin autofluorescence (SAF) a marker of AGEs measured by a validated non-invasive in vivo measurement technique.Results: The results from this study confirmed the association of diabetes and skin ageing as increased AGEs accumulation were measured using SAF and contributed evidence on gender and ethnic origin on AGEs variations. This study opens the path of further investigation into the identification of significant effects of diabetes on major facial skin complexion parameters.

“…Gender and ethnic factors may have an in uence on SAF. However, their impact has not been as consistently determined as that of ageing [29,30]. In this study SAF was reported higher in men than in women (Table 4).…”

“…These dermoscopic features include large amounts of keratin ( 6 ). Porphyrins present in keratin are the most likely candidate for nUVD detection, since 400-nm wavelength reactivity is typical of the Soret band of porphyrins ( 7 ). On the other hand, pseudo-networks were most frequently non-identifiable by nUVD.…”

“…The skin is the largest organ of the human body and exhibits significant variation according to anatomical site. There are limited systematic studies of normal human skin fluorescence, particularly as a function of skin topography . Before applying fluorescence EEM for skin cancer or other disorders, it is important to characterize how cutaneous autofluorescence varies according to regional factors.…”

Background and Purpose:Although cutaneous autofluorescence has been utilized for evaluation of skin conditions, there is a paucity of data on normal human skin autofluorescence and its dependence on anatomical site. The objective of this study is to use excitation-emission matrix spectroscopy to quantify and characterize skin autofluorescence at different body sites. Methods: Ten anatomical sites from 30 healthy volunteers were measured with a double-grating excitation-emission matrix spectrofluorometer. Results: For the 10 body sites evaluated, there were four overall patterns of autofluorescence: skin from the head and neck exhibits high superficial and low bilayer fluorescence; the dorsal forearm and dorsal hand have both low superficial and bilayer fluorescence; the upper inner arm and back have high superficial and intermediate bilayer fluorescence; while the palm and thumbnail have both high superficial and bilayer fluorescence. The corresponding fluorescence excitation-emission peaks for these patterns were as follows: head and neck, 3 peaks at 290-300/330-350, 360-380/460-485, and 380-420/610-630 nm; dorsal forearm and dorsal hand, 2 peaks around 295-300/345-360 and 385-395/460-485 nm; upper inner arm and back, 3 peaks around 295-300/335-355, 335-340/390-410, and 375-390/455-480 nm; palm and thumbnail, 3 peaks around 285-300/345-355, 335-345/390-410, and 365-390/450-480 nm. Conclusion: Cutaneous fluorescence varies in distinct patterns according to anatomical site, due to the component fluorophores present, skin thickness, and the degree of melanization and long term sun exposure. These EEM patterns for normal skin should be accounted for when interpreting fluorescence signals from disease states and can also be used to guide the selection of optimal wavebands when applying this optical modality.
