A scientist at MIT in America is saying he hasn't showered in 12 years - he instead uses a spray that introduces 'good bacteria' to his skin.
Dave Whitlock, a chemical engineer, decided to eschew traditional bathing more than a decade ago and use the live bacteria spray, which was invented by a company called AOBiome which he co-founded.
The spray, called Mother Dirt, aimed at people who want to eradicate soap from their lives, has to be applied twice a day, reports The Telegraph.
The company claims we do not have enough bacteria on our skin, and we are obsessed by washing it all off with soap.
And Whitlock doesn't plan to start showering; he uses Mother Dirt every day and hopes the rest of the world will join him. "I would like a billion people a day to use this," he said.
Mother Dirt has won an award for being one of the most innovative products of 2015. The company says you can still shower and use the product - you just spray it on directly after you bathe.
The company website says: "In our modern world, with the rise of probiotics, DIY cosmetics, no-poo products, and other natural skin care solutions, it can be difficult to figure out exactly what it means to live healthy and have healthy skin.
"We seem to have overlooked the very important ecosystem of the skin microbiome. Much like our gut relies on active probiotics and other gut bacteria to restore health, the biome of the skin needs to maintain certain bacteria on the skin for health."
