The Derm-Scientist Advantage
Scientific evidence and personalization are cornerstones of modern dermatology. Dermatologist-scientists with dual expertise like Dr. Lewinson not only are skilled practitioners, but also directly create new knowledge and innovative solutions where none previously existed. This rare combination of skillsets provides Dr. Lewinson's patients with state-of-the-art, evidence-based approaches tailored uniquely to each patient, matching the right treatments to the right person.
​
Dr. Lewinson's engineering background facilitates deep analytical skills, along with technical precision in utilizing complex surgical repair techniques, laser and energy-based devices, biological targeted therapies, and advanced understanding of facial structure, muscle and skin biomechanics to optimize aesthetic outcomes.
Clinic
Dr. Lewinson primarily practices out of Rejuvenation Dermatology, Calgary South. This one of Canada's largest and premier facilities for medical, surgical and cosmetic dermatology with state-of-the-art equipment and resources to ensure optimal treatment plans can be tailored for each unique patient.

Science & Media
Dermatologists with significant experience in science and innovation is rare. While many dermatologists participate in clinical trials, few take leadership roles in the development of new dermatologic knowledge. Dr. Lewinson is a highly recognized scientist in addition to being an expert dermatologist, where he has developed AI and Machine Learning tools for personalized treatment matching, and has significant experience in biomedical device development, data analytics and clinical trials.
He has over 100 publications in peer-reviewed journals and conference proceedings and has presented internationally. Some of his work has been featured in media outlets such as TIME Magazine, Vogue, and the Wall Street Journal, and he has been awarded numerous national scientific awards.
