Skin photoprotection and consumption of coffee and polyphenols in healthy middle‐aged Japanese females

Abstract

Coffee and polyphenol consumption was associated with low facial pigmented spots in Japanese middle-aged females. We speculated that coffee helps protect human skin from photoaging, and polyphenols, including chlorogenic acids, may contribute to the decreased hyperpigmentation of pigmented spots.

Facial skin photo‐aging and development of hyperpigmented spots from children to middle‐aged Japanese woman

“…showed the pigmented spots increased by age and subjects living in southern area shows more hyperpigmented . VISIA ™ is a facial image analyzer, and we also observed a correlation of VISIA pigment spot scores and age in middle‐aged Japanese women with low coffee consumption. However, there has been no information of UV pigment spot status in younger generation and also onset age when pigmented spots appear.…”

“…Skin condition measurements were conducted as described at the previous report . Briefly, pigmented spot scores were measured by the facial image analysis system VISIA ™ Evolution (Canfield Inc., Fairfield, NJ, USA) using ultraviolet light (UV pigmented spots) (Figure ).…”

Ingestion of Coffee Polyphenols Improves a Scaly Skin Surface and the Recovery Rate of Skin Temperature after Cold Stress: A Randomized, Controlled Trial

“…Subjects with an initially low RR included 7 individuals in the CPP group and 8 individuals in the Placebo group (a total of 15 subjects). The results of RR analysis of those two subgroups revealed that the RR-increasing effects of CPPs were more pronounced than in the comparison of the final analysis set, and the difference between these two subgroups was significant (F (1,14)511.6, p,0.01) at 4 wk (Fig. 4B).…”

“…The subjects of this study included healthy Japanese women between 25 and 35 y of age. This study was approved by the Ethics Committee of the Kao Corporation in accordance with the principles of the Declaration of Helsinki (Approval number: [13][14][15][16][17][18][19][20][21][22][23][24]. In addition, subjects only participated after receiving a sufficient explanation of the purpose and content of the study and providing informed consent.…”

“…The daily ingestion of coffee containing approximately 300 mg coffee polyphenols (CPPs) continuously for 12 wk has been reported to improve blood pressure and vascular endothelial function and to reduce visceral fat (10)(11)(12)(13). In addition, CPPs have been reported to decrease the hyperpigmentation of pigmented spots on the skin (14). The intake of CPPs is thus thought to have pleiotropic functions, but the effects of CPPs on dry skin remain unclear.…”
