Worried about wrinkles? Textile scientist Jeff Gabbay suggests you sleep on the problem.

Mr Gabbay is the founder of Israel-based medical-device company Cupron, which has developed a pillow case made with copper oxide that he claims can reduce the appearance of fine lines and crows' feet. Clinical trials claim to show that those who used the pillow for four weeks demonstrated a statistically significant reduction in numbers of wrinkles than those using conventional bedding.

Mr Gabbay, 60, who has a background in textile engineering and biochemistry, says the company used its expertise in making copper-based wound-healing medical dressings to develop the pillow. He tells People: "We had identified the ability to stimulate the body to create new tissue to close a wound, primarily beginning with the stimulation of collagen. So, we had some copper pillow cases made up and noticed that after a few days of lying on the pillow case, lines on the face started to fill out."

The theory is that the perspiration from the skin releases copper ions from the pillow cases, which stimulates the production of collagen underneath the skin. The pillow cases are already available to buy in Israel and the US, priced at around £17. They will soon be on sale in the UK. More than 10,000 have been sold in the past few months.

So is this the new Botox? "We are safer," he claims. "Botox works by relaxing muscles, not reducing wrinkles, but why would anyone want to inject themselves with one of the most toxic substances known to man?"

He adds: "I have been sleeping on the pillow for two-and-a-half years. I am 60 and have no crows' feet any more."
