Following the publication of this article, the authors noted errors in the legend of Figure 3. Part a should read as “ZMPSTE24 transcript levels decrease after broadband light (BBL) treatment.” Part b should read as “ZMPSTE24 transcript expression is higher in untreated old skin compared with untreated young skin by quantitative reverse transcription-PCR (RT-qPCR).” The authors regret the error.
