Pomegranate is a dual-purpose resource using as both medicine and food. Pomegranate contains a variety of nutrients and physiological active ingredients with high nutrition.
Pomegranate husk is rich in polyphenols, which are about 10.4% to 21.3% of its dry weight, Including punicalagin, antipomegranate, pomegranate kiosk A, pomegranate kiosk B and so on, among which punicalagin accounts for 80%- 85% of the total polyphenols. The content of flavonoids in pomegranate husk was about 6.65% of its dry weight, including a variety of flavonol phytoestrogens.
Pomegranate fruit contains various biologically active compounds such as polyphenols, flavonoids and phytoestrogens. Also, it has shown antioxidant, free radical-scavenging, cardio and cerebral blood vessel-protecitng and menopause-delaying properties. The skin-beautifying effects and the action mechanisms of punicosides include skin-moisturing, ultra violet-resisting, wrinkle-preventing, acne-removing and skin-whitening activities. As one kind of natural, safe and effective skin-protective substance, punicosides are hopeful to get wider applicaitons in cosmetics in the future.
The skin-beautifying effects of punicosides are as follows:
The appearance of healthy skin depends on the moisture content of the cuticle. Lack of moisture will not dry the skin, affect beauty, but also can seriously affect the physiological metabolism of the skin. Chronic dehydration leads to rough skin and wrinkles. The moisturizing function of pomegranate polyphenols stems from its moisturizing and inhibiting effect on skin water-retaining enzymes. Pomegranate polyphenol molecular structure contains a large number of phenolic hydroxyl groups. It can achieve deep moisturizing effect by inhibiting the activity of hyaluronidase.
Studies have shown that pomegranate polyphenols and their extracts protect the skin from uv damage and reduce pigmentation and tumor cells proliferation caused by UVA.
