Changes in acne lesion assessments from baseline to week 24

	Trifarotene 50 µg/g N = 121	Vehicle N = 121	P value*
Mean total lesion counts per half face	− 70.0%	− 44.9%	< 0.05
Mean inflammatory lesion counts per half face	− 76.3%	− 48.3%	< 0.05
Mean non-inflammatory lesion counts per half face	− 61.4%	− 32.1%	< 0.05
IGA success rates**	63.6%	31.3%	< 0.05

*Percent change analysis was not adjusted for multiplicity; thus, analysis P values are nominally significant

**IGA success = clear/almost clear and ≥ 2-grade improvement
