World-Class Skin Care for a World-Class City

“Invest in your skin. It’s going to represent you for a very long time.” – Linden Tyler

At All Dermis, we know what it’s like to live in New York City. The constant bustle, on the move, fast-paced way of life can be invigorating, but can also take a toll on one’s health. Our skin, the body’s largest organ, is no exception, as daily work hard / play hard routines and environmental stressors take their toll. Not to mention the hassle of finding time in one’s schedule to make an appointment for preventive or precautionary skincare.

That’s why we are trying a different approach from the standard dermatology office. With convenient appointments, quality care, and a central focus on the patient, we hope to make visiting the dermatologist an easy and healing experience. Whether you’re a lifelong skincare fanatic, or a first-time visitor looking to explore anti-aging treatments, we encourage you to book an appointment. We think you’ll be glad you did.

Our Mission & Vision

Our mission is simple: To be New York’s best dermatology office by offering high-quality care, friendly service, and uncompromising integrity. Our vision is a city in which all residents have access to the dermatologic care they need for healthy, vibrant skin.

Leading-Edge Treatments


Modern Anti-Aging and Boosts

Locally Owned & Operated

If you hadn’t noticed, many of NYC’s dermatologists have sold to private equity groups. Not here. We are physician-owned and operated. We’ll leave the bankers to Wall Street, not your skin health.

Highly Trained

Beyond Dr. Chan’s academic training, he completed his internship in medicine at Case Western Reserve University and his residency in dermatology at Ohio State University.

Values Driven

Our values, as a team, are the foundation of everything we do. These include a commitment to exceptional service, transparent communication, and quality care. 

Skin Care

Why ignore that spot of concern any longer? Why hide your face with makeup? Let us help you achieve clear, glowing skin. From acne treatments to Botox, Dysport, and fillers, we provide the skincare you’re looking for.

Hair Rejuvenation

Hair loss can be difficult to handle, especially when over-the-counter products only go so far. From prescription medications to platelet rich plasma (PRP) and advanced topicals, we’ll design a custom plan to boost your follicles.

Nail Health

Nail disorders are often some of the toughest to treat, which is why so many doctors avoid handling them altogether. Bring us your most challenging nail concerns, and we promise we’ll do our best to get them healthy and strong.

Our Best Credential? Happy Patients.
