The purpose of this study is to investigate consumers' perception of natural toothpaste by age and examine natural toothpaste perception after the paraben incident. The survey was distributed through SNS as a self-administration method and conducted from March to April 2018. A total of 212 adults were surveyed, and 25 individuals were randomly selected for each age group. A total of 100 subjects were analyzed. All collected data were analyzed using the SPSS 20.0 software (IBM SPSS statistics 20, IBM Inc, Chicago, IL, USA) program. The questionnaire was analyzed using cross-tabs analysis.The use of natural toothpaste was higher in the female group (48.6%) than in the male group (21.4%). Regarding the reason for purchasing natural toothpaste, the female group showed the highest response rate for purchase by self (27.8%), while the male group showed the highest response rate for recommendation by an expert (50.0%). Regarding the reason to use natural toothpaste, the highest response rate was for recommendation by acquaintances (41.2%) in the female group, and greater efficacy than conventional toothpaste (28.6%) and recommendation by acquaintances (28.6%) in the male group. Of the males, 15 (53.6%) had heard of the paraben toothpaste case, while 13 (46.4%) had never heard of it; therefore, more males had not heard of the case. Of the females, 57 (79.2%) had heard of the paraben toothpaste case, while 15 (20.8%) had not. Since more females than not had heard of the case, they had higher awareness of the case than males. Regarding the change of toothpaste after the paraben case, there was no significant difference. Age, experience using natural toothpaste, efficacy of natural toothpaste, changes in toothpaste due to paraben's monthly income, and perception of parabens between men and women vary greatly.
