    Area of Science:

    • Dermatology
    • Biomedical Engineering
    • Analytical Chemistry

    Background:

    • Accurate sebum excretion measurement is crucial for evaluating dermatological drugs, including anti-androgens and retinoic acid derivatives.
    • Current methods for measuring sebum excretion have limitations, such as inaccuracy at high sebum levels and being time-consuming for technicians.

    Purpose of the Study:

    • To re-examine existing sebum excretion methodologies.
    • To develop a modified, accurate, and efficient photometric technique for measuring sebum excretion.

    Main Methods:

    • Development of a modified photometric technique.
    • Utilization of a robust and portable machine for data acquisition.
    • Validation of the technique across all sebum production levels.
