Ageing is a natural process. Wrinkles and grey hair are the most visible signs of aging. The market is flooded with anti-wrinkle products. But there is always scope for better products.

A team of scientists led by Procter & Gamble studied the link of genes with wrinkled skin so that better products to stop aging of skin were developed.

Research team led by Dr. Jay Tiesman, principal scientist at P&G Beauty, Procter & Gamble's cosmetic division identified 1,500 separate genes that determine the amount of time a person takes to stay wrinkle free. These genes could be the possible reason why some people age "faster" than others.

Researchers used data generated by the human genome project. Researchers also found 8 major ways through which the skin ages and these ways are managed by a specific group of genes. Researchers also indicate that lifestyle also contributes in aging process.

Dr. Jay Tiesman said: "The human genome project has made it possible for us to analyse ageing right down to the hundreds of genetic changes that happen in our skin as we get older."

One of the most important processes is hydration. With the passage of years the genes that control this process loses their ability to retain water diminishes which leads to wrinkles.
