Who Is Dr. Dusan Sajic?

Dr. Dusan Sajic (MD, PhD, FRCPC, FAAD, ABAARM) is a dermatologist and the founder of deRMA Skin Institute in Guelph, Ontario. He earned a PhD at McMaster University in 2007, his MD at Western University in 2010, and completed a five-year dermatology residency at the University of Toronto in 2015.

His training in order:

• Honours BSc in Biology, McMaster University
• PhD, McMaster University (2007), in molecular immunology, virology and inflammation
• MD, Schulich School of Medicine & Dentistry, Western University (2010)
• Dermatology residency, University of Toronto (2010 to 2015)
• FRCPC (Dermatology), Royal College of Physicians and Surgeons of Canada (2015)
• Fellow of the American Academy of Dermatology (FAAD) (2016)
• Charter member, Canadian Laser and Aesthetic Specialists Society (2021)

He’s also a published researcher. He co-authored “Neutrophilic dermatoses: an update,” a review in the American Journal of Clinical Dermatology in 2014 (PubMed 25154386). His Guelph practice has also been a study site for registered clinical trials in psoriasis, alopecia areata and atopic dermatitis (ClinicalTrials.gov).

Why Does a Research Background Matter in a Skin Clinic?

Inflammation sits underneath many of the conditions dermatologists treat every day, including acne, rosacea and eczema. A PhD spent studying immunology and inflammation shapes how Dr. Sajic approaches those conditions: understand the mechanism first, then choose the treatment.

That habit carries into cosmetic care too. Skin, fat, collagen and bone all change with age, and they don’t change at the same rate. So a single treatment rarely addresses everything a patient notices in the mirror. Isn’t it better to know which layer is actually driving the change before deciding what to do about it?

What Is the 5-Dimension Skin Plan™?

The 5-Dimension Skin Plan™ is the framework Dr. Sajic developed to assess facial aging in five layers before recommending any treatment: bone, fat pads, collagen and elastin, the skin’s surface, and muscle movement. It’s the approach the OK! Magazine feature mentions by name.

In practice, it means a consultation starts with assessment rather than a menu. Treatments are then sequenced and combined to address the layers that matter for that person, instead of applying one device or one product to everything. You can read how the five dimensions work and the anatomy behind them in our detailed guide to the 5-Dimension Skin Plan™.

What Does This Mean for Patients in Guelph?

Nothing changes about how you see Dr. Sajic. He practises at deRMA Skin Institute, 33 Farley Drive, Unit #8, in Guelph. The clinic offers both medical and cosmetic dermatology.

• Medical dermatology (OHIP-covered conditions such as acne, rosacea or a changing mole) needs a referral, for example from your family doctor or a walk-in clinic. Do I need a referral? explains how it works.
• Cosmetic care doesn’t need a referral. It starts with a consultation.
