Effectiveness of non-ablative three dimensional (3D) skin rejuvenation: a retrospective study involving 46 patients

Photomed Laser Surg. 2010 Oct;28(5):685-92. doi: 10.1089/pho.2009.2532. Epub 2010 Oct 9.


Background: Three dimensional (3D) skin rejuvenation is proposed to be effective for all skin layers. The aim of this concept is to treat sun spots with broad-band pulse light; large pores, fine lines and vascular lesions with a long-pulsed 1064 nm neodymium-yttrium-aluminum-garnet (Nd:YAG) laser system and skin ptosis and laxity with a 1100-1800 nm infrared light source.

Objective: In this study, 46 patients treated with the 3D skin rejuvenation procedure were retrospectively evaluated to assess the effectiveness of the 3D procedure according to both patient and doctor satisfaction.

Methods: The 3D procedure was carried out over the course of five sessions with 15 day intervals between sessions. Results were judged by an experienced laser dermatologist both by direct patient examination and by comparison of "before" and "after" photographs. Results were ranked into five categories ranging from 0 to 4. At the final control, the patients were also asked to rate their satisfaction with the procedure in five categories, ranging from 0 to 4.

Results: All of our patients showed improvement, with an overall patient satisfaction score of 2.65. Female patients were more satisfied than male patients. Patient and doctor satisfaction scores were generally correlated.

Conclusions: Our clinical results indicate that the 3D procedure is an effective nonsurgical skin rejuvenation method.
