Re: Clarification of the SkinScan app

Dear Editor,

It has been brought to my attention that a rapid response has been posted to the original study by Deeks et al clarifying that the app named “SkinScan” in the Chadwick et al 2014 study is not related to the current “skinScan” app produced by TeleSkin ( as they infer in the paper, and as I reference in the editorial.

This rapid response is here:

The authors explain: “ It appears that there was more than one app using the name SkinScan at the point in time when the study was done. Chadwick et al indicate that the version of the “SkinScan” app they evaluated later became SkinVision. Thus we now believe that the data we described as relating to SkinScan would better be described as being for the an early version of the SkinVision app. We apologise to Teleskin for this error.”
