Dermatology Providers Serving the Napa Valley
Medical Dermatology in St. Helena
Our providers bring decades of experience to the full range of skin, hair, and nail conditions — from acne, rosacea, eczema, psoriasis, vitiligo, hives, rashes, and moles to complex disease like cutaneous lupus, bullous pemphigoid, and cutaneous vasculitis, plus pediatric concerns such as atopic dermatitis, warts, and molluscum. Skin cancer surveillance is central to our practice: total body skin examinations help us find actinic keratoses, basal cell carcinoma, squamous cell carcinoma, and melanoma at their earliest and most treatable stages, and we work to prevent them with photodynamic therapy for widespread precancers along with sunscreen and antioxidant guidance. Dr. Duncan is a member of the St. Helena Hereditary Cancer Consortium, so patients at elevated hereditary risk can access genetic counseling, testing, and close monitoring.
Cosmetic Dermatology & Injectables
Carlos Wolf, M.D., a board-certified head and neck and facial plastic surgeon, and Catherine Lenz, PA-C are expert injectors offering botulinum toxin (Botox® and Dysport®) for forehead lines, frown lines, and crow’s feet, hyaluronic acid fillers including Restylane® and the Juvéderm® Collection, and collagen-stimulating Sculptra® — with Dr. Wolf holding VIP membership in the Liquid Facelift Association. For resurfacing and tightening, we offer AQUAGOLD® fine touch™ microchanneling, medical microneedling, radiofrequency microneedling with Agnes RF and Scarlet SRF to shrink jowls and tighten the neck and face, the Aerolase® Neo laser for rejuvenation, acne, rosacea, and unwanted blood vessels across all skin tones, and Clear + Brilliant® for texture, pores, and hyperpigmentation. We also provide sclerotherapy for leg spider veins and Latisse® for fuller eyelashes.
Skin Lab Napa Valley: Medical-Grade Skin Care
At our Skin Lab on Adams Street, expert Skin Therapists start with a consultation and build a personalized regimen — and because they partner directly with our medical providers when appropriate, the team can reach for prescription-strength treatments to maximize your results. Services include medical-grade chemical peels for acne, discoloration, and enlarged pores; dermaplaning for instant exfoliation; a personalized Acne Facial with manual extractions; HydraFacial MD®, the only hydrodermabrasion procedure combining cleansing, exfoliation, extraction, hydration, and antioxidant protection with no downtime; the Intraceuticals Oxygen Facial for sensitive and acne-prone skin; a Rosacea Facial that calms redness in even the most sensitive skin; and NeurotriS™ PicoWave MicroCurrent to tone the facial muscles. Open Monday through Saturday.
