Abstract

The objective of the study was to investigate the influence of a food supplement rich in antioxidants on the antioxidant status of the skin. For this reason, the blue-green algae Spirulina platensis powder was used for oral application during eight weeks. The effect of oral application of the antioxidant-containing Spirulina platensis on characteristic skin aging parameters, e.g., concentration of cutaneous carotenoids and the collagen/elastin index (SAAID), was investigated in vivo. A significant average increase from 2.67 ± 0.86 arb. units to 3.25 ± 0.93 arb. units (p < 0.001) in the cutaneous carotenoid concentration was detected subsequent to oral application of the carotenoid-containing Spirulina platensis powder, showing a significant improvement of the antioxidant status of the skin. A slight but not significant increase (p = 0.33) in the dermal SAAID mean values was measured from −0.54 ± 0.11 to −0.51 ± 0.11 subsequent to oral intake of Spirulina platensis powder. View Full-Text
