PHILOSOPHY - the way we think


Our Credo

We are dedicated to providing the best dermatology care, the latest advanced technology, and most importantly – honest, solid advice.

All too often, we are bombarded with mass media, internet information and consumer advertising regarding our skin care and treatment options This is confusing and keeps us wondering, “What really is the best treatment out there for me?” Whether you have been diagnosed with melanoma, have cystic acne, or you have dark circles under your eyes - we are dedicated to guiding you through your options and directing you to the most proven methods for cure and improvement. Our goal is to bring you an educated, research-backed approach so that our knowledge and expertise will translate into the right option for you.

Our doctors and staff stay abreast of the latest research and academic protocols that result in the most effective treatments and best outcomes. We do not recommend procedures that don’t work. Frequently, we are encouraged to buy the newest, “greatest” procedure…but that treatment may produce little results. It is our intention to sift through the hype for you and help you make an educated decision with the best outcome in mind. We also believe that everyone is human and fragile. With that in mind, we take every step to assure you are taken care of from the minute you step foot into our office until your journey is complete to your satisfaction.

DR ZENA'S PYRAMID

Dr. Zena Gabriel designed a treatment pyramid to help simplify the range of aesthetic procedures available today.

There are so many types of aesthetic treatments on the market that patients get confused. It’s hard to know the right path to take and to figure out what procedure is best for you. The Treatment Pyramid is a paradigm that helps our patients understand the full range of aesthetic treatments and services available. The base of the pyramid begins with sunblock. This is the least invasive yet most important and relevant intervention we all must do. The pyramid peaks with a facelift which is considered an invasive surgical procedure and not relevant to all people.

Within the pyramid, Dr. Zena has stratified the treatments between MAINTENANCE and CORRECTION. Once we achieve radiant skin, we must “maintain” our healthy glow using some basic annual and daily treatments. We will recommend these maintenance therapies and customize a protocol for you to help you look radiant through all your skin's stages of life. However, if there is an aesthetic area that one wishes to CORRECT, then you move up the pyramid into the level of procedures that correct those flaws and imperfections. With this approach, Dr. Zena educates her patients and guides them toward the protocols that are individualized and relevant. This analysis is unique, customizable and very understandable so that each patient leaves with a meaningful, tangible and guiding tool. We will recommend these maintenance therapies and customize a protocol for you to help you look radiant through all your skin’s stages of life.

DR ZENA'S SIGNATURE FOUR

Dr. Zena has created a methodology for analyzing someone’s skin with a systematic approach. t times, we look at ourselves and see someone tired-looking or older than we feel.

A We’re not sure where the specific problem lies.“Is my skin is dull?” “Are the circles under my eyes the main problem?” “Are my cheeks drooping?” These questions are common and can be misdirected.

Dr. Zena believes perfect skin has four features: Even COLOR, Smooth TEXTURE, ample VOLUME, and taut ELASTICITY. She uses this tool to analyze these four features independently so that her patients can target the specific areas of need.

No one wants to waste time and money on procedures that aren’t going to correct the problem. This methodology helps patients steer clear of those missteps and invest in options that make sense and show results.

Dr. Zena’s Signature Four is her unique analysis system. With it, she has helped thousands of patients achieve more radiant skin through personalized education and analysis.
