Abstract
Background:
Proper evidence-based classification and grading of a disease such as acne are important in guiding medical practitioners to properly diagnose diseases and treat patients.
Objective:
This is a review of the present classification of acne in order to delineate modified approaches of acne treatment.
Methods:
The available literature was reviewed, including searches from 7 databases based on the terms “classification of acne vulgaris and pathophysiology”, according to evidence-based medicine using the Cochrane risk of bias tool.
Results:
From a total of 10,121 studies on acne classification, 51 full-text articles were assessed and 13 studies were included after screening for acne classification.
Conclusion:
The European-evidence-based guideline (EDF) classification fits best. We propose a modified classification in 4 categories to improve the management of each stage of acne.
