Background The three‐grade acne classification (mild, moderate, severe) is widely used to define the licensed indications of acne treatments, and for therapeutic decision‐making in clinical practice, but its reproducibility has never been assessed. Methods Ten photographs of facial acne were scored independently by eight experts using the three‐grade acne classification. We conducted a descriptive analysis of the results, based on graphical representation of the scores for each photograph. Results Inter‐observer agreement on acne severity based on the three‐grade acne classification was very poor. Conclusion The classical three‐grade acne classification is poorly reproducible. A new rating tool accompanied by a clinical description of each severity level would be extremely useful.
