Dr. Nakatsui was recently featured as a leading expert in a major international publication on a breakthrough laser technology that is turning heads across the dermatology world.

If you’ve ever wished for a skin resurfacing treatment that actually delivers without the extensive downtime, the intense discomfort, or the risks that have long made patients hesitate, you’re going to want to read this.

Our Medical Director, Dr. Nakatsui, was recently quoted as a featured expert in Le Journal de Mon Corps, one of France’s most respected independent digital magazines covering aesthetic medicine and surgery. The article, titled “Laser Coring: The New ‘Cold’ Laser Technology to Rejuvenate the Skin,” dives deep into a next-generation laser treatment that Dr. Nakatsui has been working with for several months–and his clinical insights take centre stage.

What Is “Laser Coring”?

The concept behind laser coring is elegantly simple: instead of ablating the entire surface of the skin uniformly, the laser removes microscopic columns of skin tissue — called “cores” — separated by zones of healthy, intact tissue. This healthy tissue then acts as a scaffold, driving faster, safer, and more effective skin regeneration.

What makes the UltraClear laser different from conventional fractional lasers is its unique “cold” wavelength of 2,910 nm and its ultra-rapid pulse delivery. Rather than generating intense heat that spreads to surrounding tissue, which is what causes burns, scarring, and prolonged redness, UltraClear keeps tissue temperature within a safer range. This makes it significantly safer for all skin types, including darker and more pigmentation-prone complexions.

Even more innovative is its spiral coring pattern: instead of penetrating tissue in a continuous, uniform column, the laser leaves micro-zones of healthy skin intact within each core. The result? Less thermal damage, less pain, shorter recovery, and because the impacts can be placed more closely together, a larger treatment surface and more dramatic skin tightening than traditional fractional lasers.

What Dr. Nakatsui Is Seeing in Practice

Dr. Nakatsui, one of only a handful of Canadian dermatologists with extensive hands-on experience with this technology, shared his clinical perspective in the article — and his enthusiasm is grounded in real results.

He uses UltraClear’s deep “coring” mode to treat:

• Mild skin laxity along the jawline and under the chin
• Deep wrinkles around the eyes and mouth
• Acne scars

And his take on why this matters so much right now?

“Until now, the gold standard remained the CO₂ laser, which resurfaces the skin uniformly but comes with quite heavy downtime. Patients no longer want that. Fractional lasers, while gentler, can fall short on efficacy. For a while, I had no solution that was both powerful and comfortable to offer. Laser coring brings both together — and it works on all skin types. That’s a real step forward.” — Dr. Thomas Nakatsui

That says it all. For years, patients have faced an uncomfortable trade-off: accept significant downtime with aggressive treatments, or settle for milder options that may not deliver the results they’re hoping for. UltraClear is designed to close that gap.

A Versatile Technology

UltraClear isn’t a one-trick device. Its multiple treatment modes allow it to address the skin at different depths — from the deepest dermis (up to 4 mm) all the way to the outermost surface layer. This versatility means your provider can customize a treatment plan targeting your specific concerns, whether that’s volume loss and sagging, texture, tone, or overall radiance.

Why This Is Exciting for Our Patients

At Nakatsui DermaSurgery, we are always evaluating emerging technologies against the highest clinical standards before offering them to our patients. The fact that Dr. Nakatsui has already been applying this technology in practice reflects our ongoing commitment to being at the forefront of safe, effective skin care.

If you’re curious about whether UltraClear laser coring could be right for you, we’d love to talk.
