In choosing whether to consult with a plastic surgeon or a dermatologist for this treatment, I think the decision should be based on experience. Although most of the innovations and leaders in laser medicine may be dermatologists, plastic surgeons have been quick to grasp the benefits of these medical devices, so at this point, I do not see major differences between the two specialties.
I agree with Dr. Aldea, one must be careful to interpret the moniker of a laser center. Merely being able to afford a few lasers and taking a Saturday morning laser course, does not qualify one as a laser expert. There are many of these type of physicians embarking on this road to what they perceive as "riches". With the hot breath of health care "reform" bearing down on our profession, I can only anticipate even more of these centers springing up.
Getting back to names. Some can sound quite august, so do not pay attention to this to the exclusion of other factors. For instance the Laser Institute of New England sounds impressive and maybe the gynecologist running it is excellent. However, if it were my face I would trust someone whose sole practice is limited to skin care. It is difficult enough to keep abreast of advances and maintain knowledge in one's own specialty without having to learn another's from scratch and without the benefits and guidance of residency training.
So, in sum, look beyond the name.
