Water may act as a weapon against ageing, and help keep wrinkles at bay, according to a study. Scientists have recently identified 1,500 genes that determine how long people can keep their youthful looks, and found that there are eight ways in which skin ages, each controlled by different sets of genes.
However, one of the most important aspects is how well the skin gathers and retains water.
According to a study, up to 700 genes that help keep the skin hydrated become less active and less able to retain water as the cells get older, and thus lead to wrinkles.
Another factor is the levels of collagen, a molecule that gives the skin structure and strength. The genes that degrade it become overactive in older age, which also leads to wrinkles.
It has been found that there are about 40 genes that accelerate breakdown.
