Endolift® Laser Skin Tightening in London
Performed by Dr Arun Karwal.
What is Endolift?
Endolift is a minimally invasive laser treatment that uses an ultra-fine optical fibre to deliver controlled laser energy beneath the surface of the skin. Its primary purpose is skin tightening: the laser causes existing collagen fibres to contract and stimulates the production of new collagen and elastin over the months that follow, firming and lifting areas of mild to moderate laxity.
Where a small, stubborn pocket of localised fat is contributing to the problem, such as fullness under the chin, the same laser energy can be used to gently reduce it at the same time. This is a secondary, targeted effect rather than the main goal of treatment. Endolift is not a fat removal or weight loss procedure, and Dr Karwal will always be honest at consultation about whether your concern is one that Endolift can genuinely improve.
Who is Endolift for?
Endolift gives its best results where skin laxity is mild to moderate. Typically that means early jowling, a softening jawline, looseness under the chin or crepey skin on the neck, in patients who want a meaningful improvement non-surgically. Where there is significant excess skin, surgery gives a better result. Suitability for the treatment will be determined at your consultation.
How does Endolift work?
The fine 1470nm laser fibre is guided into the deeper layers of the skin, where structural change has the most impact. The heat causes an immediate contraction of existing collagen fibres, then activates fibroblasts, the cells that build collagen. Over the following three to six months these cells lay down new collagen and elastin, forming a denser support network within the skin. This is why results continue to improve for months after treatment rather than peaking on the day.
Where fat is treated, the body clears the disrupted fat cells naturally through the lymphatic system over the following weeks. Because the skin is tightening at the same time, it contracts to fit the refined contour beneath it.
Treatment areas
Endolift can treat a single area or several zones in one appointment. On the face, it is most often used for the lower face and jowls, the jawline, under the chin to treat a double chin, and for malar bags on the upper cheek. It also treats laxity on the neck and down to the décolletage. For more widespread laxity, combined areas such as the full face and neck or the lower face and under chin can be treated in a single session. Endolift can also be used on the body for the upper arms, abdomen and inner thighs. You can read more on our dedicated Endolift Body page.
Ultrasound guided Endolift
Endolift works beneath the skin, so traditionally the fibre is guided by feel and anatomical knowledge alone. Dr Karwal uses ultrasound imaging to see the layers of the skin in real time, before and during treatment. This allows him to assess your individual anatomy, confirm the depth of the fibre and deliver energy precisely to the layer that needs it, whether the aim is tightening, melting a small pocket of fat, or both.
This precision matters most where the anatomy is fine and unforgiving, such as the malar region, the neck and the jawline. Rather than estimating what sits beneath the surface, ultrasound shows all the layers underneath, allowing Dr Karwal to measure the thickness of your submental fat layer and alter the settings of the treatment for optimal results.
Results and how long they last
For most patients a single session is enough. Some tightening is visible straight away as the tissue contracts, and the full result develops over three to six months as new collagen forms. Results typically last two to three years, and in some people longer. A second session is only occasionally recommended, usually where laxity is more advanced, and it is never assumed.

FAQs

Endolift is a safe procedure with a low risk profile when performed by an experienced doctor, and Dr Karwal will talk you through all possible risks, side effects and complications at your consultation, with a detailed list provided in your consent form. The most common effects are temporary swelling, bruising and tenderness in the treated area, which settle as part of normal healing. A rare but important complication is bruising of the marginal mandibular nerve, which sits in the lower face on either side of the angles of the mouth. In a very small number of cases this nerve can become irritated by laser heat, causing temporary lip asymmetry on the affected side. Where this occurs, some patients are given a short course of oral steroids and vitamin B tablets to help speed up recovery, and it usually resolves fully within 8 to 10 weeks. To minimise this risk, treatment close to the angles of the mouth is avoided, and Dr Karwal's use of ultrasound guidance allows the depth and position of the fibre to be monitored with far greater precision than treating by feel alone.

Avoid any other facial laser treatments for at least four weeks beforehand, and stop peel-based or active skincare such as retinol one week before, as these leave the skin more sensitive to heat. On the day, arrive with clean skin free of make-up if possible, and remove earrings. Mention any regular medications or recent treatments elsewhere at your consultation so Dr Karwal can confirm you are ready to go ahead. You can eat and drink normally beforehand, as the procedure is performed under local anaesthetic, and most patients can drive themselves home afterwards.

Swelling and bruising are a normal part of healing. Most patients have mild to moderate swelling in the first three days, which then gradually reduces, with most visible signs of treatment resolved by day 14. Some patients have more pronounced swelling or temporary lumps that take longer to settle, and this is normal rather than a cause for concern. A compression garment is worn continuously for the first three days, then as much as possible for up to a month, and you will be shown a daily massage technique that supports drainage and helps the result settle smoothly. Many patients return to desk-based work within the first week, but if your role is public facing, plan around the garment and the two-week settling period. The full aftercare protocol is on our post care information page and is provided in writing on the day. Follow-up appointments are included, and Dr Karwal remains directly contactable throughout your recovery.

A facelift remains the most powerful option for significant excess skin, but it involves surgery, general anaesthetic, scarring and weeks of recovery. Endolift sits between skin boosters and surgery. It produces genuine structural tightening, with most visible recovery settling within two weeks. For mild to moderate laxity it achieves a meaningful improvement, but it will not replicate a surgical result, and Dr Karwal will tell you honestly if surgery would serve you better.

The simplest way to think about it is depth. Endolift works beneath the skin on the deep structural layer, tightening the tissue, melting small pockets of fat and stimulating fresh collagen, which firms areas like the jawline, jowls and neck. Our fractional ablative CO2 laser, the Lumenis AcuPulse, works on the surface, resurfacing the outer layers to improve texture, tone, pores, fine lines and sun damage. If your main concern is laxity, Endolift is usually the priority. If it is surface quality on otherwise well supported skin, CO2 may be enough on its own. Many people from their mid thirties onwards have both concerns at once, which is why the two are often planned together, though not always on the same day. Dr Karwal will plan the right sequence for your skin at consultation. You can read more on our CO2 laser page.

Yes, and combinations are often where the best results come from. Endolift addresses laxity in the deeper tissue, so it pairs well with treatments that improve the skin surface and quality, such as CO2 laser resurfacing, Sunekos or Profhilo. Where volume loss is part of the picture, dermal filler can be added once healing is complete. Dr Karwal will sequence any combination safely and will only recommend what genuinely adds to your result.

Malar bags are the soft, puffy areas that sit on the upper cheek over the cheekbone, just below the lower eyelid. They are not the same as ordinary under-eye bags. They are usually a combination of lax skin that has lost support, small pockets of fat, and fluid that pools because natural drainage in that part of the face is poor. Endolift treats exactly the layer where the problem sits. It tightens the lax tissue so the area is better supported, melts the small fat pockets that add to the fullness, and as the tissue firms over the following weeks, drainage tends to improve, which helps settle the puffiness.
-
Adding filler to a poorly draining area can make a malar bag look worse rather than better, because the extra volume tends to hold more fluid. This is why careful assessment matters, and why a treatment that supports and tightens the area is often more appropriate than one that adds volume. Dr Karwal will assess which approach genuinely suits your anatomy rather than defaulting to filler.
