With high standards of professional care and advanced resources for skin cancer diagnosis and treatment, ERderm is a top-choice dermatology practice in the Newport Beach, California, area. Dermatologists Edward Rohaly, MD, and Samuel Peterson, MD, FACMS, FAAD, and their team have over 100 years of combined experience improving skin health and aesthetics. 

At ERderm, the team relies on state-of-the-art laser technology and photodynamic therapy for common skin concerns like wrinkles and pigmentation issues. They also use light-based treatments for conditions like rosacea, acne, and acne scars. Also, in the realm of cosmetic dermatology, ERderm offers Botox┬« injections for wrinkles and hyperhidrosis. 

A key specialty at ERderm is skin cancer diagnosis and treatment. Using the latest available procedures, the team evaluates and treats basal cell carcinoma, squamous cell carcinoma, and melanoma. They rely on surgeries and topical therapies for skin cancer treatment and use Mohs surgery, an advanced technique that preserves healthy skin surrounding basal and squamous cell cancers. 

ERderm is also a leading provider of ALVAC-MART-1 for melanoma in Orange County. Few practices offer this advanced vaccine that targets a specific protein within melanoma cells. 

The ERderm team provides screenings and other preventive strategies to help patients avoid the need for skin cancer treatments in the first place and can help patients perfect their skin care routine for overall skin health and beauty. 

Spending lots of time in the sun can cause sun damage and skin cancer, but fortunately, modern dermatology can keep skin healthy at any age. Schedule an appointment over the phone or online at ERderm for excellent dermatological care today.
