Best Westchester Doc
Board-Certified Dermatologist -- Chappaqua, NY
Lydia M. Evans, MD
Arnold C. Toback, MD

For 20 years, I have been working with patients to provide the best cosmetic and medical dermatologic care in the Chappaqua/Westchester area and beyond. I want all of my patients to be well informed, because informed patients can make better decisions about the health and appearance of their skin. That is why I have included extensive information covering a full array of topics in this website. These include the ever-expanding array of cosmetic procedures as well as medical dermatological problems, their diagnosis, and treatment.

We strive to make our office comfortable, convenient, and responsive to your needs. We want you to feel confident that, when you choose this practice for your dermatologic and/or cosmetic care, you are working with professionals who are qualified, experienced, and caring.

Practice Overview
My practice is dedicated to offering state-of-the-art cosmetic and medical dermatology. It is of paramount importance to me to stay abreast of the latest developments in aesthetic procedures and the diagnosis and treatment of dermatologic health conditions. I constantly evaluate new technologies dedicated to the health of your skin and the enhancement of your appearance. I like to work with patients to develop a plan that will work for them, whether addressing a medical condition or developing a cosmetic program. You will be treated as an individual with attention paid to your specific cares and needs.

During my 11 years as consulting dermatologist to L’Oréal Paris, leading the global beauty company’s consumer education efforts, we pioneered bringing accessible, dermatologist-inspired skincare to women in their drugstore.  Together we communicated age- and skin-specific solutions inspired by best practices in dermatology.  My practice is committed to continuing this work not only on the product front, but also in the cosmetic dermatology arena.  I hope you will look to this website for information and guidance on how to choose from the latest developments in anti-aging to achieve a fresher, more youthful appearance.

Gone are the days when the scalpel was the only answer:  Modern dermatology can address the same signs of aging that affect the skin -- such as wrinkles, sagging, and dyspigmentation -- through modern, in-office technology and techniques that can be far less costly and invasive.  I hope you will explore these options on my website, and I welcome your questions about how to achieve a fresher, natural-looking you without surgery.

I hope you find our website useful, and I invite you to contact our office for an appointment.


We are proud to bring you the latest, most advanced procedures available. We have a staff specially trained to meet your needs. Offering a variety of procedures, we can help you revitalize your skin's natural glow.
