Before and after:
look at conditions and sources.

Twenty-six original figures from peer-reviewed papers are shown unmodified. Figures whose original papers identify women or Korean or Chinese research institutions are listed first; nationality or ethnicity is not inferred from appearance.

How to review

Are lighting and angles the same?
How many days and sessions later?
Were other treatments combined?
Are you confusing this with your own result?
