A skin cream which heals sun damage as it happens and blocks a process which causes wrinkles has been created by scientists, according to Daily Mail.

Researchers say it is a next-generation sun cream, which not only protects against sunburn but rapidly repairs low-level damage done to skin by the sun in real time.

The cream contains an artificial version of melanin, a natural molecule in the skin which most people know produces a sun tan, but which also heals the skin after it is hit by the sun's rays.

Scientists have now created a 'super-melanin' which works even better.

Used in a skin cream, it captures and neutralises harmful 'free radicals' – molecules in the body triggered by ultraviolet light from the sun which can destroy the collagen needed for plump, springy, youthful skin.

Used for a long time, the cream could potentially prevent the sagging, fine lines and wrinkles which appear on people's faces after years of sun exposure.

Dr Kurt Lu, a member of the scientific team behind the breakthrough, and a dermatologist and skin biologist from Northwestern University in the US, said: 'Many people try remedies after being sunburnt to soothe the soreness, or a cream to reduce the inflammation, but there was really nothing before this to actually repair the damage done to skin by the sun.

'This repair is needed continuously because if you walk bare-faced every day in the sun, you suffer a low-grade, constant bombardment of ultraviolet light.'

Professor Nathan Gianneschi, the bioengineer and chemist at Northwestern University who helped to make the super-melanin, said: 'We set out to find a scientific solution to a problem with no existing solution - the damage the sun does to the skin.

'When it comes to face creams claiming to tackle the ageing effects of the sun, there is a lot of hype and hope.

'But we have a cream with science behind it which can continuously repair the skin as it is exposed to the sun, and we hope it might be available for daily use within 18 months.'

Researchers tested the super-melanin mixed with water, which they applied to skin donated by 10 people who had undergone plastic surgery.

The skin was treated with a drug designed to cause blistering, like that seen from extreme sun damage which causes a sun burn.

When the super-melanin skin cream was applied to the 10 skin samples, half did not develop blisters.

This was compared to skin samples not treated with the cream, which all showed damage.

This is evidence that the artificial melanin can prevent and repair skin damage, although more research is needed using the cream applied directly to people's faces and bodies.

Further evidence that the cream could help the skin heal faster from sun damage in real time came from its use on the skin of mice exposed to ultraviolet radiation like the sun's rays.
