摘要

Objectives: The Authors located in the 2 Portygal´s major cities (Lisbon and Oporto) using this new tecnhique - 1470 nm Diode Sub-dermal laser, compareted their experiences in Face and neck Laxity, in terms of skin quality, thightening, non-surgical lifting effect. Introduction: Skin Laxity occurs naturally with age progression, causing in many cases, disconfort , social impairment, and is a major cause of patient concern. It has many causes and tend to worsen in age. There are many medical approches to skin laxidy, from surgical Lifting in most severe cases, to non surgical medical treatment in litgh and mild cases. One of the most recent treatments is minical invasive sub-dermal laser specially 1470nm Diode Laser whitch cause skin retraction and stimualtion of new colagen fibers. Materials / method: The authors used several scales to measure skin laxity in face and neck. Excluding severe laxity cases, whitch were referenced to plastic surgery face lifting. The light and mild cases were submited to 1 or 2 session of minimal invasive Diode 1470 nm Sub-Dermal Laser, for skin thightening and redensification, followed by lymphatic drainage massage. The authors applied a local anesthesia, and a fiber using a fanning technique for aplying the laser treatments. Results: Both in face and neck, skin laxidy improved most significantly in ligth and mild cases. The results wore more notable after 3/4 months after the last treatment and lasted for at least one year (depending on the previous laxidity status). There were mininal side effects and general improvement of skin quality and thightening were notable in all patients. Conclusion: The Diode 1470nm Laser permited a significant improvement with minimal/no downtime in skin quality, redensification and thightening, allowing a minimal invasive non-surgical aproach to skin laxidy both in face and neck.
