Her practice serves the full spectrum of skin health needs for adults in New York City and the surrounding metropolitan area, from routine annual skin exams and common inflammatory skin conditions through complex chronic dermatological disease management and surgical skin cancer care.

Medical dermatology is the broad clinical foundation of Dr. Lefkowicz’s practice. She provides expert evaluation and ongoing management of a wide range of skin conditions — including psoriasis, eczema, contact dermatitis, acne, rosacea, skin infections, and inflammatory rashes — approaching each condition with thorough diagnostic evaluation and individualized treatment planning. Her particular expertise in psoriasis — a chronic, immune-mediated skin condition that significantly impacts quality of life and often requires sophisticated systemic or biologic therapy — reflects her deep engagement with one of dermatology’s most clinically complex and rapidly evolving treatment landscapes. For patients with chronic or recurrent skin conditions, she provides structured long-term management with regular monitoring and therapy adjustments, ensuring that treatment remains effective and well-tolerated over time.
