Development and evaluation of a Global Acne Severity Scale (GEA Scale) suitable for France and Europe

Background and objective  Many acne grading methods exist; however, there is no agreed‐upon standard. Our objective was to create and validate a reproducible acne assessment scale for rating the severity of juvenile facial acne suitable for use in France and Europe.
