Why we chose fibre-laser technology over the original Endolift® device.
A doctor-led account of the technology-fit decision behind Cosmedocs' second-generation laser-fibre lifting programme — and why, in 2026, we still stand behind it.
The short answer
We didn't reject Endolift®. We looked at it carefully, then chose a dual-wavelength (980nm + 1470nm) fibre-laser platform because it addressed both skin laxity and small pockets of stubborn adipose tissue in a single pass — which is what the majority of our patients actually present with. It's cheaper for them, and clinically it gives us more range per session. That's the whole decision, said plainly.
The moment the decision came up
Around 2022 we were rebuilding our energy-based device stack at Cosmedocs. Radiofrequency and microneedling RF were doing well for surface tightening, but a specific patient profile kept coming through the door — mid-thirties to mid-forties, low body fat, early jowl or sub-mental softening, and a very clear brief: "I don't want surgery, I don't want filler, I want the underlying structure tightened."
Intra-dermal laser fibre was the obvious category. The question was which platform. The name everyone knew was Endolift® — Eufoton's 1470nm diode fibre system, launched in the mid-2010s, well-marketed in Italy and increasingly visible in London. So we did what any clinic should do before committing to a six-figure device purchase: we audited it against the alternatives.
What we actually evaluated
Three things drove the technology-fit review:
- Chromophore selectivity vs the patient's real anatomy. 1470nm is water-selective and produces excellent collagen contraction — but it is not the wavelength you would choose if you were designing a device to remodel adipose tissue. For a patient whose jawline is being obscured by a soft sub-mental fat pocket, 1470nm alone leaves half the anatomical problem un-addressed.
- The evidence base beyond the brand. 980nm diode has a decade-plus of peer-reviewed use in endovenous laser ablation (Proebstle, Almeida, Kabnick et al.) and laser lipolysis (Katz & McBean, Dermatol Surg 2008). It's not experimental. Combining it with 1470nm through a single fibre isn't a leap — it's an engineering convergence of two mature, separately validated wavelengths.
- Delivery model and price transparency. The branded 1G route in the UK typically lands at £1,500–£3,500 per zone. When we mapped the true clinical cost — consumables, doctor time, review appointment — the honest number was closer to £450. A device choice that forced us to charge three times that would have compromised our transparent-pricing commitment.
Why "just buy the Endolift®" wasn't the safer answer
A reasonable challenge: if Endolift® is the established name, why take the harder route?Two reasons.
First, buying a branded 1G device would have meant delivering a treatment we knew was clinically narrower than what our audit patients needed. That is a subtle form of over-promise — telling a patient "yes, this will handle your jawline" when the platform can only really handle half the tissue in question. Under GMC Good Medical Practice, that kind of misalignment between claim and capability is exactly what we're meant to avoid.
Second, "safe" in aesthetic medicine isn't the same as "familiar". The safer route, clinically, is the one where the device does what the anatomy actually requires. Familiarity is a comfort for the clinic; anatomical fit is a benefit for the patient.
What the second-generation platform actually is
The platform we chose delivers 980nm and 1470nm through a single 200µm optical fibre, inserted through a fine cannula tract under topical and local anaesthesia. In practice that means:
- 1470nm handles collagen contraction and dermal tightening — the classical Endolift® effect.
- 980nm handles adipose remodelling and small-vessel coagulation in the same pass.
- One insertion point per zone. No layered sessions to reach the fat layer separately.
- UKCA and CE-marked device — regulatory posture identical to any other UK-legal aesthetic laser.
We deliver this protocol as XL Endolaser. The name is ours; the underlying physics is drawn from two well-established diode-laser literatures.
The audit — what changed after 12 months
After a full year on the 2G platform we reviewed outcomes across our first cohort:
- Single-session sufficiency. ~82% of jawline / sub-mental patients did not need a second treatment within the following 12 months. On the 1G literature, comparable cohorts typically report 60–70% single-session sufficiency for the same anatomical brief.
- Downtime. Essentially unchanged — 2–3 days of visible swelling, minor bruising in a minority of patients. No increase in complication rate.
- Patient-reported outcome (POSAS / self-rated). Higher satisfaction on the "jawline definition" domain specifically, which is where the adipose channel does its work.
- Price point delivered. £450 per zone, stable, with no upward drift.
None of that says the 1G device is bad. It says the 2G platform mapped better onto the specific patient cohort we were treating.
What we won't claim
For clarity — and for trademark and ASA compliance — a short list of things we do not say:
- We do not say we perform Endolift®. We don't. Endolift® is a specific branded device by Eufoton s.r.l.
- We do not say XL Endolaser is "the same as" Endolift®. It's the next generation of the same underlying idea — that's a different claim.
- We do not say 1G Endolift® doesn't work. It does. Our position is about technology fit for our patient mix, not about denigrating a competitor's platform.
Who signs off on this decision
Every case at Cosmedocs is performed by a GMC-registered doctor. The laser-fibre lifting programme sits under my personal clinical accountability as Medical Director. I also serve as Lead Trainer for laser fibre lifting at the Harley Street Institute — the training body that credentials many of the doctors delivering this category of treatment across the UK. If the technology choice were wrong, I would be the first person accountable for it, both to my patients and to the profession.
The honest close
Choosing your platform is one of the least glamorous decisions a clinic makes. It happens years before the patient walks in, in a conference room with a spreadsheet, an audit and a shortlist. We chose fibre-laser over the branded 1G device because it fit our patient anatomy better, sat on a stronger combined evidence base, and let us deliver the treatment at a price that reflected its true clinical cost. Three years on, we'd make the same decision again.
"We chose the technology that fit the anatomy, not the brand name. That's the whole decision, said plainly."

Questions we've been asked
Why didn't Cosmedocs simply buy an Endolift® device?
We evaluated the original Eufoton Endolift® platform when we were building our laser-fibre programme. It's a well-engineered 1G device, but it's single-wavelength (1470nm) and its licensing model bundles a premium price into every treatment. Our clinical audit of 300+ jawline and sub-mental cases showed most patients presented with a combined skin-laxity and adipose concern — something a dual-wavelength (980nm + 1470nm) platform addresses in one pass. We chose the technology that fit the anatomy, not the brand name.
Is dual-wavelength fibre laser genuinely evidence-based?
Yes. 980nm has an extensive peer-reviewed literature in endovenous laser ablation (Proebstle et al., J Vasc Surg, 2005 onwards) and laser lipolysis (Katz & McBean, Dermatol Surg, 2008). 1470nm intra-dermal tightening is documented in aesthetic dermatology from 2013 onwards. The 2G approach combines two mature, individually validated wavelengths — it isn't experimental physics, it's an engineering convergence.
Doesn't Endolift® have more published data because it's older?
It has more branded case series, yes. But the underlying wavelength (1470nm) is the same physics we deliver. The additional 980nm channel we deliver has its own separate, deeper evidence base from vascular surgery. So the total published evidence supporting our 2G protocol is arguably larger — it just sits across two literatures rather than one branded one.
Are you saying Endolift® doesn't work?
No — Endolift® works. It's a valid 1G option and the clinics that deliver it well produce good results. Our position is narrower: for the patient mix we treat at Cosmedocs (mid-30s and up, combined laxity + adipose concerns), a dual-wavelength platform gives us more clinical range per session. That's a technology-fit decision, not a claim that 1G doesn't work.
How do we know the technology choice is doctor-driven, not commercial?
Two things. First, the 2G route is less expensive per zone (from £450 vs typical £1,500+ for London Endolift®), so the commercial incentive would have pointed the other way. Second, every case is performed by Dr Ahmed Haq, who is Lead Trainer for laser fibre lifting at the Harley Street Institute — the technology choice sits under his GMC-registered clinical accountability, not a marketing team.
What if a patient specifically wants Endolift®?
We say so, honestly. If a patient wants the branded Endolift® experience specifically, we'll refer them to a reputable London provider rather than misrepresent our platform as the same device. Trademark clarity matters — both for patient trust and for regulatory transparency under the ASA and GMC Good Medical Practice guidance on advertising.
