About the Practice

As a board-certified dermatologist and dermatologic surgeon, Kristen Aguirre, MD, is passionate about helping patients of all ages take care of their skin. At Advanced Skin Care Medical Center in Fullerton, California, she provides expert treatments to address skin issues ranging from psoriasis and rosacea to skin cancer and skin revitalization procedures — like intense pulsed light (IPL) therapy to improve the condition, texture, and appearance of her patients’ skin.

Dr. Aguirre is an Orange County native and was excited to return to the area when she completed her education. She graduated with high honors from the University of California (UC), Davis before moving to Columbus, Ohio, to earn her medical degree at Ohio State University. She found her passion for dermatology while helping run a local free clinic while she studied medicine. Dr. Aguirre expanded her training with experience at both the University of Texas Southwestern Medical Center in Dallas and back at UC Davis.

After completing her medical degree, Dr. Aguirre completed her internal medicine internship at Santa Barbara Cottage Hospital and her advanced dermatology residency at UC Irvine. During her residency, she served as the Resident Director of Surgical and Cosmetic training and received the Resident Teacher of the Year award. She’s continued to train with dermatology experts in subspecialty areas, including Mohs micrographic skin surgery, pediatric dermatology, laser science, and surgical reconstruction.

Outside of her practice, Dr. Aguirre enjoys spending time with her family. They play in their vegetable garden, cook together, and explore the parks and playgrounds in their neighborhood.

How Dermal Fillers Work to Fight Aging

As you age, your skin becomes thinner, dryer, and more lined -- often due to the decrease in production of natural compounds. Dermal fillers replace some of these compounds to restore a more youthful complexion.
