Mangos are rich in β-carotene and other carotenoids, along with several phenolic acids that may provide oxidant defense and photoprotection to the skin. The objectives of this study are to investigate the effects of Ataulfo mango intake on the development of facial wrinkles and erythema. A randomized two-group parallel-arm study was conducted to assess 16 weeks of either 85 g or 250 g of mango intake in healthy postmenopausal women with Fitzpatrick skin type II or III. Facial photographs were captured at weeks 0, 8, and 16, and wrinkles at the lateral canthi and erythema at the cheeks were quantified. Skin carotenoid values were measured with reflection spectroscopy. Deep wrinkle severity decreased significantly in the 85 g group after 8 ( = 0.007) and 16 ( = 0.03) weeks compared to baseline measures. In contrast, those in the 250 g group showed an increase after 16 weeks in average wrinkle severity ( = 0.049), average wrinkle length ( = 0.007), fine wrinkle severity ( = 0.02), and emerging wrinkle severity ( = 0.02). Erythema in the cheeks increased with 85 g of mango intake ( = 0.04). The intake of 85 g of mangos reduced wrinkles in fair-skinned postmenopausal women, while an intake of 250 g showed the opposite effect. Further studies feeding 85 g of mangos are warranted.
芒果富含β-胡萝卜素和其他类胡萝卜素,以及几种可能为皮肤提供抗氧化防御和光保护的酚酸。本研究的目的是研究摄入芒果对面部皱纹和红斑形成的影响。进行了一项随机两组成平行臂研究,评估了健康绝经后皮肤类型 II 或 III 的女性分别摄入 85 g 或 250 g 芒果 16 周的情况。在 0、8 和 16 周时拍摄面部照片,并定量测量外眦处的皱纹和脸颊处的红斑。使用反射光谱法测量皮肤类胡萝卜素值。与基线相比,85 g 组在 8 周(= 0.007)和 16 周(= 0.03)后,深皱纹严重程度显著降低。相比之下,250 g 组在 16 周时平均皱纹严重程度(= 0.049)、平均皱纹长度(= 0.007)、细皱纹严重程度(= 0.02)和新出现皱纹严重程度(= 0.02)均增加。摄入 85 g 芒果后脸颊处的红斑增加(= 0.04)。摄入 85 g 芒果可减少皮肤白皙的绝经后女性的皱纹,而摄入 250 g 则产生相反的效果。进一步的研究需要摄入 85 g 的芒果。
