Here at the Z Skin Center we utilize a combination of ground breaking medications, therapies and technologies to assist in correcting unsightly skin disorders and the effects of aging.
We believe in not only treating our patients for specific skin conditions, but educating on the causes of specific skin conditions and how to prevent them from re-occuring if possible.
We take pride in providing our patients with results that help them look and feel the way they deserve.
Dr. Zanelli is regarded as one of the nation’s experts in facial restoration after fat loss from HIV disease and treatment. He has been performing corrective treatments for facial lipoatrophy for more than 12 years, and he is the only physician in Northern California who performs microdroplet silicone injections for permanent correction of HIV lipoatrophy.
Loss of fat (lipoatrophy) in the face contributes to an aged appearance, and if severe can make a patient look ill when in fact they may feel very well. Mild facial fat loss may be due to normal aging and severe fat loss may be secondary to HIV and treatment regimens. Facial fillers such as Sculptra are now available for correction of lipoatrophy. For permanent correction Dr. Zanelli uses an FDA-approved medical-grade silicone, which is approved for intraocular injection; Its use for lipoatrophy thus is considered off-label. The superior result that hundreds of patients have received with microdroplet silicone treatments for lipoatrophy has changed their lives.
Dr. Zanelli also works closely with Dr. John Meyer, the world-renowned director of the Department of Radiation Oncology at St. Francis Medical Center. Dr. Meyer utilizes a specialized low-dose radiation therapy to reduce enlarged parotid (cheek salivary) glands associated with HIV disease.
