Q: What do you like about Dermatology?

A: I like that there are many aspects to Dermatology. From Surgical treatment of Cancers to Treatment of Rashes like Psoriasis with Medications and everything in between. Skin is an organ that everyone sees and as such both the patient and I can see the work that is being done. I also enjoy that it is one of the few specialties where we can actively try to fight the aging process through scientifically proven methods.

Q: Why should patients ask to see a Dermatologist for their skin?

A: Dermatology is a medical specialty that takes 5 years after Medical School to master. Indeed at the end of the residency one needs to pass an exam to be officially certified to call themselves a Dermatologist. Think of it like Martial Arts. Becoming a specialist is like getting a black belt. I’m sure blue and brown belts know a lot, but I don’t think I would take my kids to a place where a black belt wasn’t the teacher. I think you should ask for no less for your skin.

Q: I see a lot of places offering Skin services – mostly cosmetic procedures like Botox, Fillers, Lasers without a Dermatologist. What are your thoughts on this?

A: Great question. First of all, I prefer to call it Aesthetic Medicine, because that is exactly what it is. There are many intricacies and nuances in assessing a patient’s needs and understanding how their unique anatomy plays into designing and executing a proper treatment. Furthermore, like any branch of medicine, there are numerous side-effects that can happen – particularly in the hands of a sub-optimally trained person! Most of the currently available aesthetic treatments were developed and advanced by Dermatologists for a reason. While there are weekend courses for non-specialists, I don’t think you can properly learn this stuff over a weekend. Moreover, due to their short nature, they are almost always cookie cutter type solutions designed to fit the average face.  Unless your face is a cookie, I would suggest that you stick to a board certified Dermatologist.
