Dr. Fei-Shiuann (Clarissa) Yang, MD

Dr. Fei-Shiuann (Clarissa) Yang is a physician practicing in Boston, Massachusetts. Her areas of care include medical dermatology, skin cancer treatment, atypical mole evaluation and treatment, laser procedures, and cosmetic dermatology, such as VI Peels. Dr. Yang emphasizes an evidence-based approach to patient care and education. She notes that while some peptides are FDA-approved medications supported by years of clinical research, many others discussed on social media still lack evidence from human trials. She clarifies that FDA review for compounding pharmacy use differs from full FDA approval, which demands extensive testing for safety and effectiveness. Dr. Yang informs patients that compounded peptides can be helpful when no approved option exists, but they carry unknowns regarding their efficacy, long-term safety, and consistent quality across makers.
