This prospective study aims to evaluate the responsiveness of the validated investigator global assessment (IGA) and composite area index score for keratosis pilaris by data collection through treatment and scoring sessions held at a private practice and relevant statistical analysis.

This study aims to explore the reliability and validity of newly developed Investigator Global Assessments (IGAs) in scoring the severity of pemphigus. IGAs are simple 5-point scales ranging from clear - severe and are preferred by the FDA as endpoints in clinical trials.

This validation study aims to develop a standardised investigator global assessment (IGA) score for keratosis pilaris and test the validity and reliability of the score through a one-day scoring exercise held at a private practice and compare it to a standard 0-4 IGA score specifically defined for keratosis pilaris.
