Dr. Nnedimma Ozoani

Dr. Nnedimma Ozoani is a medical professional based out of the Castleknock, Ranelagh, South Anne Street, and Terenure clinics in Dublin, as well as the Naas clinic.

Afterward, she went on to further her career by embarking on a Masters in Surgery at the Royal College of Surgeons in Ireland in Dublin, as well as a degree in dermatology from University College Dublin. Dr. Nnedimma believes that aesthetics should fit into a larger self-care routine, complete with a healthy diet, regular skincare, and lots and lots of SPF. Her favorite treatment (for both her patients and herself) is Profhilo, as she finds that not only does skin tone, texture and moisture content improve but makeup sits better on the skin after treatment. When it comes to practicing aesthetic medicine, Dr. Nnedimma loves the ways in which it gives her the opportunity to both make features more pleasing to the eye and help her patients feel like the best versions of themselves. It’s amazing how a small tweak can have such a profound impact on someone’s life. She loves her role in helping people discover their confidence and put their best face forward.

Dr. Tunde is of the firm belief that aesthetic medicine–especially injectables and fillers–should only be performed by licensed medical professionals. The fact that Sisu Clinic is doctor-led is what originally appealed to her and led her to practice here. Dr. Tunde’s approach to aesthetic medicine is to consider it as part of a larger self-care system. It is not about just getting one treatment. Patients should think of their skin as a complex structure, focusing on the whole instead of just certain areas. She believes that home care is very important as well (such as regular application of SPF, Vitamin C, and Retinol) to maintain results. Dr. Tunde’s favorite part of working in aesthetic medicine: seeing her patients smile after seeing their results. She loves that she can help them achieve stunning results in such a short period of time, strengthening their confidence with the perfect treatment.
