Dear Dr. Ricardo Baroudi,

Editor-in-chief of the Revista Brasileira de Cirurgia Plástica (Brazilian Journal of Plastic Surgery)

I would like to clarify the issue raised by Dr. Renata Oliveira regarding the manuscript "Laserlipolysis: skin tightening lipoplasty followed by safety parameters for use of diode laser with double wavelength of 924 nm and 975 nm,"¹ published in issue 26-2 of the Revista Brasileira de Cirurgia Plástica (Brazilian Journal of Plastic Surgery).

In the above-mentioned manuscript, the authors reported parameters for the application of accumulated energy at values known for different areas of the human body.

In order to clarify this, it was established that the accumulated energy for a 10 × 10 cm area of skin would be 5,000 J. In other words, we defined the energy for each 10 × 10 cm area of skin.

The only correct interpretation of the accumulated energy is that the accumulated energy is greater in larger areas. For instance, in an arm that is 20 cm long and 10 cm wide, the accumulated energy would be of 10,000 J, i.e., two times 5,000 J.

We believe we are referring to the same area, because only the interpretation described above is correct.

The safety parameters for the use of the Aspire-SlimLipo laser for the treatment of skin sagging were developed in the United States in 2010 by Craft, Lewis, Angobaldo, and Wolfenson – all pioneers of the use of this laser.

A new report on experience with this laser for the treatment of sagging skin will be published in the "Viewpoints" section of Plastic and Reconstructive Surgery in June 2012.

I thank you and Dr. Renata Oliveira for your attention and interest. I am available to answer any other questions directly at [e-mail].

Dr. Baroudi, I would like to express my great admiration for your work.

Very truly yours,

Moisés Wolfenson
