Introduction: Pityriasis Versicolor (PV) is an infection caused by Malassezia, especially Malassezia furfur, most commonly seen in adolescents and young adults. In the skin, sebum lipid is an essential ingredient in supporting the growth of Malassezia because of its lipophilic properties. Higher sebum levels are detected in some body regions, such as the face, scalp, chest, and back. Therefore, in these areas, a higher amount of Malassezia is found. Thus, sebum levels may affect the occurrence of PV. This study aims to determine the correlation between sebum levels and PV. Methods: This research studies the correlation between sebum levels and PV with a cross-sectional design on 31 subjects with PV and 31 non-PV subjects. They were treated at the Dermatology and Venereology Polyclinic, Haji Adam Malik General Hospital, Medan. The assessment was based on examining sebum levels on the chest and back of the PV and non-PV groups. Research subjects who met the inclusion and exclusion criteria underwent anamnesis, physical examination, and dermatological examination and examination with 10% KOH solution on subjects with PV. Then, all PV and non-PV subjects recorded primary data, including age, gender, education level, and sebum levels. The data collected were tabulated and presented in a frequency distribution table and analyzed statistically. Results: The age with the most suffering from PV was <20-40 years, as many as 24 people (77.4%). The most affected sex was male as much as 87.1%, and the highest level of education affected was high school as many as 25 people (80, 6%). The mean level of sebum in the chest of the PV group was 20.97 mg/cm2, while in the non-PV group, it was 16.29 mg/cm2. The average sebum level in the back of the PV group was 24.13 mg/cm2, while in the non-PV group, it was 21.71 mg/cm2. There was no significant difference in the sebum levels on the chest and back between PV and non-PV groups. Conclusion: There was no significant difference in sebum levels between PV and non-PV. Indicating other factors are influencing the onset of the disease.
