Second-generation Endolift — the science of dual-wavelength laser fibre lifting.
A decade after Endolift® defined the category, laser fibre lifting has quietly evolved. Here's what changed, why it matters clinically, and how the 2G protocol delivers more per pass.
The short answer
Second-generation Endolift combines 980nm (targets adipose & vasculature) and 1470nm (targets water & collagen) through a single 200µm optical fibre — one pass, two tissue layers. It's the natural evolution of a technology that started with 1470nm alone, and it's what Cosmedocs delivers as XL Endolaser on Harley Street.
1. Where Endolift® started
When Eufoton introduced Endolift® in the mid-2010s it solved a specific engineering problem: how to deliver a controlled dose of 1470nm diode laser under the skin without a scalpel. A 300µm optical fibre, inserted through a fine cannula tract, allowed real intra-tissue collagen contraction with minimal downtime. It was a genuine breakthrough — and it still works.
But 1470nm is chromophore-selective: it targets water and, indirectly, collagen. Adipose tissue is far less absorptive at that wavelength. Patients with sub-mental fullness (double chin) or jowl fat pockets often needed layered sessions — or a combination with a separate lipolysis modality — to reach their goal.
2. What the second generation added
The 2G protocol delivers 980nm alongside 1470nm through the same fibre. 980nm is not new — vascular surgeons have used it in endovenous laser ablation since the early 2000s, and body-contouring literature established its role in laser lipolysis over a decade ago. Its chromophore selectivity favours haemoglobin and adipose lipid — the exact tissue types 1G Endolift® left largely untouched.
Delivered together, the two wavelengths let one pass do two things: contract collagen in the upper dermis (1470nm) AND remodel the adipose pocket underneath (980nm). Same downtime, broader outcome.
3. Why this matters for patients over 35
Most patients researching Endolift® in their late thirties and forties aren't asking for pure fine tightening. They're describing early jowl formation, a soft jawline, or a stubborn double chin that persists despite low body fat. Those concerns sit at the interface of skin laxity and adipose accumulation — exactly where 2G outperforms 1G.
4. The Cosmedocs protocol — XL Endolaser
At Cosmedocs on Harley Street, we deliver 2G laser fibre lifting as XL Endolaser. Every treatment is doctor-led by Dr Ahmed Haq (Lead Trainer for laser fibre lifting at the Harley Street Institute), performed under topical anaesthesia through a single insertion point per zone, with a 3-month clinical review included.
- UKCA & CE-marked device
- 200µm micro-fibre — smaller than 1G, better tract healing
- Dual 980nm + 1470nm through one channel
- From £450 per zone versus £1,500+ for legacy Endolift® in the UK
5. Is 2G always the right choice?
No. For younger patients (late 20s to early 30s) with pure fine laxity and no adipose component, 1G Endolift® or even non-fibre modalities like microneedling RF may be sufficient. The 2G evolution shines specifically when both tissue layers need addressing in one appointment.
“The most successful cosmetic treatment isn’t the one that changes a face the most. It’s the one that helps a person feel more aligned with the image they already had of themselves.”
Frequently asked
What is second-generation Endolift?
Second-generation laser fibre lifting combines two diode wavelengths — 980nm and 1470nm — through a single 200µm optical fibre inserted intra-dermally. The original Endolift® device (Eufoton, c. 2015) used only the 1470nm wavelength. The 2G protocol addresses adipose tissue and vasculature (980nm) alongside water and collagen (1470nm) in one pass. Cosmedocs delivers this as XL Endolaser on Harley Street.
Why did the technology evolve to dual-wavelength?
1G Endolift® excelled at collagen contraction but had limited effect on the adipose layer — a limitation for patients whose primary concern was jowl or sub-mental fullness. Adding the 980nm channel (well-established in endovascular and body contouring) let the second generation address both tissue types in a single insertion. Same downtime, broader clinical outcome.
Is dual-wavelength scientifically supported?
Yes. 980nm diode has decades of peer-reviewed use in endovenous laser ablation and laser lipolysis. 1470nm has an established literature in intra-dermal laser tightening. Combining them through one fibre is the natural next step and mirrors the way vascular surgeons have used dual-wavelength endovenous systems since the mid-2010s.
Does the 2G evolution replace Endolift®?
It doesn't replace the device — it evolves the technique. Endolift® remains a valid 1G option. XL Endolaser is what we recommend at Cosmedocs because it addresses more of the patient's concerns in one appointment, doctor-led, at a lower price point per zone.
Where can I get 2G Endolift in the UK?
Cosmedocs on Harley Street offers XL Endolaser — our 2G dual-wavelength protocol. Delivered by Dr Ahmed Haq, Lead Trainer for laser fibre lifting at the Harley Street Institute. From £450 per zone.
