Dr. med. Riikka
Veltheim

Specialist in Aesthetic Plastic Surgery

Dr. Riikka Veltheim has 23 years of experience in aesthetic and reconstructive plastic surgery. Dr. Riikka Veltheim has been a licensed physician since 1998 and a specialist in plastic surgery since 2005, after completing her training at Karolinska Hospital. At the time, Dr. Veltheim was the youngest surgeon in Sweden ever to obtain her specialist title. She defended her doctoral thesis on acute respiratory distress syndrome in 1999 and wrote her dissertation during her medical studies. She then conducted research at the Karolinska Institutet on breast cancer, which can develop during pregnancy or immediately after birth, and on bone regeneration. Today, together with Professor Per Heden, she conducts research into facial ageing and the effects of plastic surgery on bodily functions and brain health.

During medical school, she served on the board of the student association and on the board of the Swedish Society for Aesthetic Plastic Surgery (SFEP). At Karolinska Hospital, Dr. Veltheim was responsible for the national registry for severe weight loss and was part of the reconstruction team for women after breast cancer.

From Karolinska Hospital, Dr. Veltheim was appointed as a young plastic surgeon at the Academic Clinics, where she worked as a partner and specialist in plastic surgery from 2005 to 2024. As a mother of three now grown-up children, she is passionate about everything that can give women a better quality of life after the effects and damage of pregnancy and childbirth on the female body. Dr. Riikka Veltheim is specialized in facial rejuvenation procedures, with a particular focus on advanced facelift techniques. She completed her extensive training in Sweden and further deepened her expertise through numerous international courses and fellowships in the fields of facelift surgery, mid-facelifting and forehead lifting procedures.

With many years of surgical experience and a refined aesthetic sensibility, Dr. Veltheim is regarded as one of the leading plastic and aesthetic surgeons in her field. Her approach combines precision, innovation, and a strong commitment to natural-looking, long-lasting results tailored to the individual needs of her patients.

She is now a part of the team at the successful Beethovenstrasse clinic as a specialist in plastic surgery.
