Revealed: The 'miracle' ingredient in wrinkle cream that DOUBLES the production of skin-plumping collagen
- A chemical called MatrixylT used in some anti-wrinkle creams may double the amount of collagen in skin
- Collagen is needed to keep skin elastic and give it a plump, youthful feel - but production declines with age
- Scientists say MatrixylT can help the skin produce more
But a nagging question always remains over whether anti-wrinkle creams make any difference at all.
Now researchers at the University of Reading say a chemical used in some of these creams really can work - by doubling the amount of collagen produced by the skin.
Collagen is a protein that gives skin its strength and elasticity. With the amount we make falling as we age, the protein has become a key ingredient of many creams that claim to rejuvenate the skin and smooth away wrinkles.
Many anti-ageing products claim to stimulate the production of it to make skin look younger, plumper and firmer. Others contain collagen in the cream itself.
But with competition in the skincare market so fierce, there is scant published research on the effectiveness of various ingredients - particularly the 'miracle' ones that claim to turn back time.
Previous research has also indicated that expensive collagen-containing creams are a waste of money.

Two years ago, scientists at the University of Bath said the collagen molecules in the enticing-sounding lotions and potions are so large that very few make it through the skin.
As a result, they sit on the surface of the face until they are rubbed off or washed away.
In the new research, the Reading researchers decided to test the effectiveness of a particular product on collagen - a peptide called MatrixylT.
This is said to encourage the skin to produce more collagen.
The researchers found that provided the concentrations are high enough, the product can almost double the amount of collagen that the cells in the body produce.
Ian Hamley, a chemistry professor at the university, said the study showed that products containing Matrixyl would have skin-care benefits.
He said: 'Studies like this are very important for the consumer as cosmetic companies rarely publish their work so rivals can't copy their products.'
MatrixylT was tested on skin cells in a lab, but products known to contain the chemical include some L'Oreal and Skindoctor creams.
Professor Hamley added that as well as skincare products, collagen-based materials could be used to treat wounds and enhance stem cell research.
'Collagen-based materials have immense potential in tissue engineering,' he added.
The research was independently funded by the University and the Engineering and Physical Sciences Research Council and published in the journal Molecular Pharmaceutics.
