A review of homemade cosmetics based on a study of 150 blogs and their authors.

Do-it-yourself methods have been used in many fields (cooking, home improvement, decoration, gardening, etc.) for a long time, but their application to the cosmetics sector is relatively recent and seems to be linked to a number of health scandals. The objective of this work is to analyse homemade cosmetics based on a study of blogs and their authors.
