The science of skin cream


Desorption Electrospray Ionisation (DESI) is a new scientific technique being developed that could detect how small molecules are absorbed into the skin. It allows ambient mass spectrometry to be carried out for the first time on surfaces and could have important implications for transdermal drug delivery.

A new scientific technique being developed by the National Physical Laboratory (NPL) shows how quickly particles are absorbed into the skin. It promises to be a useful tool in developing more effective topical products.

The technique – ambient surface mass spectrometry – was invented in 2004 and provides real-time analysis of chemical samples.

The National Physical Laboratory (NPL), the UK’s National Measurement Institute, is developing the metrology to make it reliable for use in areas such as chemical testing for the skin cream industry.
