CO₂ laser resurfacing is an advanced procedure that uses controlled fractional carbon dioxide laser energy to remove and renew damaged skin layers to stimulate regeneration from within. It is considered one of the most effective laser treatments for comprehensive skin renewal.
Unlike settings where laser treatments are delegated, Dr. Dusan Sajic performs the procedure himself and oversees every stage— from consultation and treatment planning to healing and follow-up. This level of physician involvement allows for greater precision, safer outcomes, and results that respect both the appearance and health of your skin.
As the skin heals, new, healthier skin replaces the treated tissue—resulting in smoother texture, improved tone, reduced wrinkles, and stronger skin structure. CO₂ lasers penetrate deeper than non-ablative lasers, allowing for more significant collagen stimulation and structural skin renewal.
CO₂ laser is commonly used to address:
✅ Fine lines and deeper wrinkles
✅ Sun damage and uneven texture
✅ Acne and surgical scars
✅ Skin laxity and dullness
CO₂ laser can significantly improve sun-damaged skin and texture, and is particularly effective for patients with moderate to advanced skin aging.
Because CO₂ laser resurfacing works at both the surface and deeper dermal levels, it delivers more comprehensive and longer-lasting improvement than superficial treatments.
Downtime varies depending on treatment depth, but most patients experience:
- 7-10 days of active healing
- Redness that gradually fades over several weeks
- Progressive improvement in skin quality over 3–6 months as collagen remodels
CO₂ laser resurfacing is a medical procedure that demands expertise, precision, and clinical judgment. At our clinic, every treatment is performed personally by Dr. Dusan Sajic, a board-certified dermatologist with extensive experience in laser medicine and skin cancer care.
Dr. Sajic’s background in medical and aesthetic dermatology means your treatment is not approached as a one-size-fits-all cosmetic service, but as a carefully planned medical procedure. Skin type, degree of sun damage, scarring, and long-term skin health are all considered before energy settings are selected.
Our team brings 20 years of experience to performing laser treatments— so we know how to get great results, avoid common pitfalls, and innovate to stay ahead of the curve when it comes to aesthetics.

Dr. Sajic developed deRMA Skin Institute to provide medical and cosmetic dermatology patients access to state-of-the-art technology and treatments. As a Fellow of the Royal College of Physicians and Surgeons of Canada and the American Academy of Dermatology, Dr. Sajic’s accomplishments as a researcher, educator, and dermatology innovator have made him one of Ontario’s leading dermatologists.
