We, the Editors and Publisher of the Journal of Cosmetic and Laser Therapy, have retracted the following article:
Kyu Young Seo, Dong Hyun Kim, Sang Eun Lee, Moon Soo Yoon & Hee Jung Lee (2013) Skin rejuvenation by microneedle fractional radiofrequency and a human stem cell conditioned medium in Asian skin: a randomized controlled investigator blinded split-face study, Journal of Cosmetic and Laser Therapy, 15:1, 25-33, https://doi.org/10.3109/14764172.2012.748201
Since publication, concerns have been raised about the originality of the text and data presented in the article as compared to a previous article published by the same authors in Lasers in Surgery and Medicine:
Seo, K.Y., Yoon, M.S., Kim, D.H. and Lee, H.J. (2012), Skin rejuvenation by microneedle fractional radiofrequency treatment in Asian skin; Clinical and histological analysis. Lasers Surg. Med., 44: 631-636. doi:10.1002/lsm.22071.
Taylor & Francis requested an explanation from the authors regarding the similarities between the two papers, but we received no response.
We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions.
The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as ‘Retracted’.
