    A new grading system for acne severity, using a 0-8 scale with photographic standards, has been developed. This system is reliable for tracking acne progression in clinical trials.

    Area of Science:

    • Dermatology
    • Clinical Research
    • Medical Imaging

    Background:

    • Acne vulgaris is a common skin condition requiring objective assessment.
    • Standardized methods are needed for evaluating acne severity and treatment response.
    • Existing grading systems may lack sufficient detail or reproducibility.

    Purpose of the Study:

    • To develop and validate a reliable grading system for assessing acne severity.
    • To establish a standardized scale for tracking the clinical course of acne.
    • To utilize photographic standards for objective acne evaluation.

    Main Methods:

    • A grading scale from 0 to 8 was devised for overall acne severity.
    • Photographic standards illustrating specific grades (0, 2, 4, 6, 8) were created.

    Related Experiment Videos

  • The system was implemented and evaluated in large-scale clinical trials.

    • Main Results:

    • The developed grading system demonstrated usefulness and reliability in clinical trials.
    • Photographic standards provided clear benchmarks for severity assessment.
    • The system facilitated consistent evaluation of acne status over time.

    Conclusions:

    • The new acne grading system, anchored by photographic standards, offers a reliable method for clinical assessment.
    • This system provides a permanent and regradable record of patient progress.
    • It is suitable for use in large-scale clinical trials for acne management.
