The answer to your question regarding Fraxel laser use on the neck and chest is a definite yes. Fraxel laser is a fractionated laser. This means that rather than the treating the entire outer surface of the skin at one sitting the laser treats microscopically in a tiny dot-like fashion, which leaves untreated skin, at a microscopic level, between the laser treated skin areas. This allows for much quicker healing and also allows the procedure to be safely performed on areas of the body which did not have the same characteristics as the face. Ablative therapies such as chemical peel and laser which can be used on the face cannot be used safely on the neck and chest. Fraxel laser however definitely can. We would be happy to see you in consultation to provide you with more specific information to your concerns. There is also additional information on our site regarding Fraxel laser as well as other treatment options.
