After completing her dermatology training at the Academic Medical Center (AMC) in 2012, she specialized in both general and cosmetic dermatology, with particular expertise in dermatologic surgery, skin aging, injectables, laser treatments, and regenerative aesthetic medicine. In addition to running her own clinic, she works as a general dermatologist, treating patients with a wide range of skin conditions and skin cancer.

With this vision of integrated skin health, working both externally and internally to optimize skin quality and vitality, Dr. Brenninkmeijer has partnered with Niata Longevity. This collaboration aligns with her belief that skin aging and overall health are influenced not only externally, but also internally. By combining lifestyle, nutrition, and targeted supplementation with medical skin treatments, a more comprehensive approach to longevity and skin health can be achieved.
