In a bid to help reduce the levels of skin cancer, scientists have developed a suncream that reduces the impact of UV rays and a wearable that lets you know if you’ve been in the sun for too long.
The Skin Cancer Foundation in the US says that more than 3.5m skin cancers, in more than 2m people, are diagnosed each year.
It is such a major risk to people’s health that figures from the Foundation show that over the past 30 years more people have had skin cancer than all of the other cancers combined.
Needless to say scientists and those working with technology have been working to develop preventative measures and ways to try and stop the cancer from taking lives.
One scientist from Mexico has incorporated nanotechnology into a suncream that can reduce the effects of UV rays. While another group, from Scotland, have created a wearable that helps to show the person with it on if they have been out in the sun for too long.
The scientists from Scotland have created a waterproof wristband that changes colour according to the amount of exposures the wearer has to UV radiation.
It starts yellow but turns pink as exposures increases. The colour change is caused by an acid-release agent that detects the light and a dye which responds to the pH levels in the indicator.
The wristband’s sensitivity to ultraviolet light allows it to alert the wearer to danger before it is visible on the skin.
This could be of particular benefit to those from the UK who seem to easily get sun burned while on holiday – as well as reducing the chances of skin cancer.
The wristband was developed at the University of Strathclyde in Scotland.
Scientist Joel Antonio Gutierrez from Mexico has developed a suncream that helps to reduce the effects of UV rays.
The cream, which is trying to infiltrate the highly competitive cosmetic industry, incorporates nanoparticles of titanium dioxide.
The key for the titanium dioxide product was to develop a technique to disperse the particles and avoid them collecting together.
The advantage in the formula is that using titanium dioxide nanoparticles increases the photo protective efficacy.
Since then it has been proved that the lower the particle size the better the protective UV efficiency.
