Skin aging is influenced by internal and external factors, such as changes in estrogen production and exposure to free radicals. During and after menopause, falling estrogen levels cause a decrease in general skin tone, wrinkles and sagging. Aging skin tissue typically stiffens and loses elasticity. The responsible process for this is called collagen protein glycation, and occurs because glucose forms cross-links between collagen molecules, making collagen protein less flexible.
Hormone replacement therapy (HRT) is known to preserve collagen content, elastic properties and thickness of the skin. Isoflavones are thought to have similar anti-aging effects on the skin.
It has been shown that SoyLife isoflavones have a possible anti-aging effect on skin tissue by reducing the glycation of collagen protein. As a result, it may slow the loss of skin’s elasticity.
