AIM: After oral intake, an extract from the bark of the French maritime pine reduces melasma and improves skin elasticity. Pomegranate extract inhibits tyrosinase and has an UV-protectory effect. It could be expected that the combination of both extracts in a nutricosmetic would have a beneficial effect on skin. Objective of the study was the evaluation of the effect of the nutricosmetic on the complexion of Caucasian and Asian women as well as on the anti-blotching or skin whitening effect.
METHODS: Twenty Caucasian and 10 Asian women were included into the study. Complexion, cutaneous color and color intensity of blotches were evaluated 28 and 56 days after oral intake of the nutricosmetic. The formulation contained French maritime pine bark extract, Pomegranate extract and vitamins C and E. Complexion was rated by a trained jury. Skin color was measured by spectrocolorimeter, intensity of brown spots (blotches) by VISIA systems.
RESULTS: In the Caucasian population, the aspects of “blooming and velvety skin” and of “fineness of skin texture” were improved. Spectrocolorimetric measurements revealed a significant decrease of the yellow color of the skin. In the Asian population the “greasy aspect of skin” decreased Spectrocolorimetric measurements showed a lightening effect after 56 days; a tendency to an anti-blotching effect was also seen.
CONCLUSION: These results advocate the intake of the inner-cosmetic to ameliorate the complexion radiance in both Caucasian and Asian women.
