The razor does not require expensive catridges replacements and little to no water usage. The laser razor is also environmentally friendly. 2bn razors are thrown away each year in the US and are left in land fills and gabage dumps. The razor works by using wavelengths of light which had already been discovered to be able to cut dark hair. The wavelength doesn’t emit UV.
The laser has a life of 50,000 hours and uses a single AAA battery which will last about a month depending on use. The laser is low power and eye safe. The Skarp Razor is the world’s first laser razor.
Update, 13/10/2015: Kickstarter has suspended the fundraising page for this project, due to the fact that Skarp broke the rules because a working prototype doesn’t exist.
