Our trusted and clinically proven treatments aim to enhance the health and appearance of your skin, hair, and nails.



Our beauty treatments are designed to enhance your natural beauty and restore a youthful appearance.

Our range of fillers includes the full lines of Restylane and Juvederm and other fillers upon request, each designed to address your specific concerns. If you are looking to restore your lips or volume in the cheek or the midface,  we offer specific fillers created for each location. 


Hair and nail health are often overlooked aspects of dermatology. We offer treatments for a variety of hair and nail conditions, including hair loss known as alopecia, fungal infections of the nails, and all other hair and nail conditions. Our hair restoration treatments include PRP and PRFM  (platelet-rich plasma and platelet-rich fibrin matrix) therapy offered in clinic,  as well as oral and topical medications. We also provide advice on proper supplements and hair and nail care to prevent future problems.

Rashes can be a sign of various underlying conditions. At Defining Dermatology, we offer comprehensive diagnostic and treatment services for a wide range of skin eruptions. Our approach includes daily care management, dietary management when needed,  topical treatments, oral medications, and in some cases, advanced therapies like phototherapy or advanced targeted biologic medications. We also provide education on how to prevent rashes when possible how and maintain healthy skin.


Moles are common and very often simply known "beauty marks"  as we like to call them. In some cases, however, they can transform due to genetic risks and sun damage. We offer mole examinations, biopsies, and excisions for both medical and cosmetic purposes. We also provide education on how to monitor your moles for changes that could indicate an underlying medical concern. 


Skin cancer is a serious concern, but with early detection and treatment, it can often be cured. We offer skin cancer screenings, biopsies, and a variety of treatment options, including surgical removal, cryotherapy, and topical chemotherapy. We also provide education on sun safety and the importance of sunscreen and regular in home self-examinations.
