Author's reply to the comments on the article : Hemiface comparative study of two phenol peels (Baker-Gordon and Hetter formulas) for the correction of facial rhytids

To the Editors of Surgical & Cosmetic Dermatology

In response to the letter published about the article “Comments: Hemiface comparative study of two phenol peels (Baker-Gordon and Hetter formulas) for the correction of facial rhytids”, published on this Journal, Volume 9/Number 2, we would like to thank Prof. Wam-bier, Prof. Brody and Dr. Hetter for their comments.

In fact we have detected two inaccuracies in the original article, and request that an erratum be issued.

1) On page 42, under the section Application Method, third paragraph, a 100mg tramadol vial was applied as a post-operative measure. Post-discharge analgesia was performed with 30mg codeine.

2) On page 41, under the section Introduction, sixth paragraph, “In 1950” must be replaced by “In 1960”.

Regarding the comments, we would like to clarify that the authors have deemed the chosen methodology and the Hetter formula as the most appropriate for the study in question. Concerning the quoted dates, they are related to the articles’ publication year.

Last but not least, with respect to the conclusions presented by the authors in the article, it seems that they were not clearly perceived by Dr. Hetter, for at no time did we state that phenol was of primary importance.

The study was carried out at the Universidade Estadual de Ponta Grossa (UEPG) - Ponta Grossa (PR), Brazil.
