Players obtained education to recognize post-inflammatory hyperpigmentation in advance of get the images (Text message S2). Skin heterogeneity and post-inflammatory hyperpigmentation images had been previewed before get, so you can familiarise players toward diversity and you can variability regarding pictures and you may demonstrated inside the a good randomised purchase.
