For more than two decades, carbon dioxide (CO₂) lasers have been regarded as the gold standard for treating wrinkles, acne scars and sun-damaged skin. Er lasers later offered a less aggressive alternative with faster recovery, while fractional laser technology transformed resurfacing by reducing downtime without sacrificing effectiveness.
Now another contender is taking the stage. UltraClear, a 2910 nm cold fibre laser, is being promoted as the next generation of skin resurfacing.
London’s 111 Harley Street Clinic, which offers the treatment, describe it as ‘the future of skin remodelling,’ highlighting its ability to stimulate collagen while significantly reducing downtime compared with conventional ablative lasers.
But is UltraClear genuinely a technological breakthrough, or simply another addition to the laser market?
Here’s what we found out:
The success of CO₂ laser resurfacing has always been based on controlled injury. Operating at a wavelength of 10,600 nm, CO₂ lasers target water within skin tissue. As water absorbs the laser energy, microscopic columns of damaged tissue are vaporised. This controlled injury stimulates wound healing, encouraging fibroblasts to produce new collagen and elastin over the following months.
The results can be dramatic. Deep wrinkles soften, acne scars become shallower and photoaged skin appears smoother and firmer.
However, there is a downside to the treatment. This is heat. Traditional CO₂ lasers generate substantial thermal damage around each treatment column. While this contributes to collagen contraction and skin tightening, it also produces redness, swelling and a recovery period that can extend to two weeks or longer. Patients with darker skin tones may also face a higher risk of post-inflammatory hyperpigmentation.
Er lasers reduced some of these concerns by producing less thermal injury, but many clinicians found that they also generated less tissue tightening. The challenge has therefore been to preserve efficacy while minimising collateral damage.
UltraClear seems to address this challenge. It employs a fibre-based laser operating at a wavelength of 2910 nm. Like other ablative lasers, it targets water within the skin. However, the shorter wavelength and fibre delivery system allow energy to be delivered in extremely precise micro-pulses with reduced heat diffusion into surrounding tissue.
This approach is often described as ‘cold ablation.’ The term does not mean the laser is physically cold. Rather, it refers to the reduction in unwanted thermal injury compared with conventional ablative systems.
This is a noteworthy benefit as patients often seek treatments which fit around work and social commitments, with minimal downtime.
UltraClear has also generated considerable interest due to its flexibility. Rather than offering a single treatment intensity, clinicians can select different treatment modes depending on the patient’s skin concerns.
Lighter protocols, including UltraClear 3DMIRACL, focus primarily on superficial rejuvenation. They improve dullness, pigmentation, uneven tone and early fine lines with minimal downtime, allowing many patients to resume normal activities almost immediately.
More intensive settings penetrate deeper into the dermis, stimulating collagen remodelling for acne scars, wrinkles and skin laxity.
UltraClear does not necessarily replace CO₂ in every clinical situation. Instead, many experts see it occupying the space between lighter fractional lasers and traditional high-energy ablative resurfacing. For severe photoageing and deeply etched wrinkles, experienced laser surgeons still regard fractional CO₂ as one of the most powerful resurfacing tools available.
Patients who previously declined CO₂ because of extended downtime may now consider UltraClear as a more acceptable option.
Historically, laser resurfacing has been approached cautiously in patients with darker complexions because excessive inflammation increases the risk of post-inflammatory hyperpigmentation. UltraClear’s reduced thermal profile has attracted attention because it may broaden treatment options for more diverse skin tones.
The Rise Of Combination Therapy
Perhaps the most significant development surrounding UltraClear is not the laser itself but how it is being integrated into broader regenerative treatment plans.
Plastic surgeon Dr. Yannis Alexandrides from 111 Harley Street Clinic predicts that tailored treatment protocols will define aesthetic medicine in 2026. These protocols will involve combining technologies rather than relying on individual procedures alone. At 111 Harley Street, UltraClear is already being incorporated into both surgical and non-surgical treatment pathways, alongside regenerative procedures such as nanografting and advanced recovery protocols.
This reflects a wider movement throughout aesthetic medicine. Instead of viewing resurfacing as a standalone treatment, practitioners increasingly combine laser procedures with collagen stimulators, regenerative injectables, photobiomodulation and personalised skincare to maximise long-term outcomes.
The laser initiates tissue renewal, while regenerative therapies aim to optimise healing and collagen maturation.
Professionals predict that the future of skin resurfacing is unlikely to be defined by a single laser. However, there are certain factors which they believe will differentiate the champions of the future from the rest. Treatments which allow for greater precision, reduced downtime and increasingly personalised care will more than likely stand heads and shoulders above the rest.
Considering these defining points for future success, UltraClear definitely holds a unique position in the future of beauty and aesthetics.
