Medical dermatology
Expert diagnosis and relief for contact, seborrheic, and nummular dermatitis — itchy, inflamed skin treated with personalized care at Miami Skin Center.
Contact Dermatitis — triggered by direct contact with allergens (nickel, latex, fragrances) or irritants (soaps, detergents, chemicals). Patch testing helps identify the exact cause.
Seborrheic Dermatitis — a chronic condition causing red, scaly, greasy patches on the scalp, eyebrows, sides of the nose, and chest. Linked to Malassezia yeast and oily skin.
Nummular Dermatitis — coin-shaped, intensely itchy plaques, often on the arms, legs, and trunk. Common in dry skin conditions and adults.
Identifying and avoiding triggers is the cornerstone of long-term management. Our dermatologists create individualized plans to help you achieve clear, comfortable skin.
