Lycopene presence in facial skin corneocytes and sebum and its association with circulating lycopene isomer profile: Effects of age and dietary supplementation
Lycopene is a dietary antioxidant known to prevent skin photodamage. This study aimed to examine age‐dependent presence of this carotenoid on the surface of the facial skin and in the serum as well as to measure the same parameters during supplementation with lycopene.

Summary: | Lycopene is a dietary antioxidant known to prevent skin photodamage. This study aimed to examine age‐dependent presence of this carotenoid on the surface of the facial skin and in the serum as well as to measure the same parameters during supplementation with lycopene. Serum samples and samples from facial skin surface were obtained from 60 young (under 25 years old) and 60 middle‐aged (over 50 years old) volunteers. Similar samples were taken from 15 middle‐aged subjects during 4‐week supplementation with lycopene (7 mg/day). Serum lycopene levels and isomer profiles were analyzed by HPLC. Lycopene in desquamated corneocytes and the sebum from facial skin surface was determined using lycopene‐specific fluorescent monoclonal antibodies. The results demonstrated that there was no age‐related difference in serum lycopene levels, but a higher proportion of (all‐E)‐lycopene was detected in the “young” group (37.5% vs 26.2% in the “middle‐aged” group; p |
