Homemade cosmetics - Health issues and risks

Out of 150 blogs offering homemade cosmetics recipes, the authors can be perfectly identified by surname and first name in 55% of cases. Just over 35% of the authors of these blogs hide behind a pseudonym, and less than 10% are completely anonymous. With just one exception, all the bloggers are women. As can be seen, blogging is mostly a solo activity, with only five of the 150 blogs studied being run by two people. Level of education, when mentioned, is representative of the French national average.
