Kiwis contain large amounts of the water-soluble vitamin C, which is needed to produce collagen. Collagen is a connective protein that helps to firm your skin. Production of collagen decreases with aging, causing skin to lose elasticity. Collagen-stimulating ingredients, like kiwi extract, may be added to skin care products to slow the appearance of aging.
Vitamin C not only firms skin, it repairs it. Kiwis have more vitamin C than a comparable amount of oranges. Vitamin C helps cuts and abrasions to heal and it also works to prevent rough, dry skin. In addition to skin care products that contain kiwi extract, go for the internal vitamin C boost with a fresh salad of kiwi, strawberries and citrus slices to help protect skin from the inside out.
Kiwis are a good source of vitamin E. Topical vitamin E may decrease facial lines and the depth of wrinkles. Studies of vitamin E as an external application are inconclusive but ongoing. Vitamin E has been shown to reduce UV-induced skin cancer in animal testing. Sunblock does offer you protection from harmful ultraviolet (UV) rays. Wrinkle cream may or may not erase those frown lines.
You can’t turn the clock back but you may be able to slow it down. Kiwis are a major source of antioxidants that can delay the effects of aging throughout the body. Antioxidants neutralize the free radicals that can damage healthy cells and hasten the process of degeneration, including changes in skin thickness, elasticity and firmness.
