Biological changes in our skin occur around the age of 55, a few years after the menopause. With the reduction of oestrogen levels, our skin changes and, for some of us, gazing lovingly into the mirror may become a thing of the past. Our skin becomes thinner, less plump and drier. Mentally we may be raring to go, but our faces become tired, pale and no longer in sync with our youthful state of mind. Even if we've resigned ourselves to our skin's ageing process ; such as wrinkles, loss of volume or liver spots ; we don't want to lose our natural glow. Even with a good dose of blusher, it's hard to hide our tired features. This is all down to slowing circulation and impaired dermal vascularisation. The colour component of our skin decreases and the skin dulls. Throw in some wrinkles and our skin's surface appears uneven, as light becomes poorly reflected. Here's how to keep a bright, rosy-cheeked complexion.
