Our bodies change over the years, so it’s only natural to get loose skin under the chin, especially after losing weight and as we age. If that’s something you’ve been worried about and want to know whether there’s anything you can do to tighten that loose skin, keep reading!
This article will explain what exactly causes this and offer some methods on how to tighten skin under chin, from daily skincare habits to professional treatments.

Loose skin under the chin refers specifically to skin laxity: the skin has lost enough structural support that it no longer sits taut against the underlying tissue.
This is different from submental fat that is common after weight gain (the excess fat beneath the chin, often called a double chin). It’s also different from platysmal bands, the vertical bands of neck muscle that run from the jawline down the front of the neck and become more visible with age.
Skin laxity in the lower face and neck area is one of the most frequently discussed concerns in aesthetic medicine. It shows up early for many people.
From around the mid-20s, your skin loses its ability to produce as much collagen – it happens slowly but steadily. Collagen and elastin are the structural proteins that give your skin its firmness and elasticity. As collagen production slows and existing fibres degrade, your skin gradually loses the ability to spring back into place. The neck is particularly vulnerable because the skin there is thinner than facial skin. It also has fewer sebaceous glands and is subject to constant movement.
Gravity adds to this over time. The platysma (the broad, thin muscle that covers the front of the neck) becomes less taut with age, and the supporting ligaments of the lower face loosen. The result is skin that begins to drape rather than sit flat, a condition sometimes called turkey neck.
Significant weight loss, especially rapid weight loss, can leave the neck area with extra skin that the body does not easily reabsorb. When body fat accumulates under the chin over a long period, the skin stretches to accommodate it. After the fat is lost, whether through lifestyle changes or a medical procedure, that stretched skin does not automatically retract. How much it retracts depends on age, skin quality, and genetics.
Some people are simply predisposed to earlier or more pronounced skin laxity in this area. If a parent had noticeable neck bands or a double chin from their forties, there is a reasonable chance their children will too, independent of overall body fat.
Sun exposure is one of the most significant accelerants of the skin’s aging process. UV radiation breaks down collagen and elastin directly. It also generates free radicals that damage skin cells. The neck and dĂ©colletage are often among the least protected areas. People apply SPF to their face and stop at the jaw. So, sun damage, accumulated over decades, shows up as sagging skin, crepey texture, and uneven skin tone.
Smoking is also an important factor. It restricts blood flow to the skin and depletes vitamin C, which is essential for collagen synthesis.
Then, there is what is often called tech neck: the sustained forward flexion of the neck that comes from looking down at phones and screens. Holding that position for hours each day, over the years, creates repeated creasing in the neck area. It also weakens the postural muscles that keep the neck upright.
The short answer: yes, you can tighten mild to moderate laxity under the chin without surgery.
Non-surgical methods work primarily by stimulating collagen production and improving the structural quality of the skin over time. They do not remove excess skin. They do not replicate what a neck lift can achieve surgically. For people with early-stage laxity, mild sagging skin, or good skin quality after modest weight loss, non-surgical treatments can produce dramatic results: gradual, cumulative, and maintained with periodic sessions. Most non-surgical skin tightening procedures require multiple sessions, patience, and ongoing maintenance. We’ll discuss them in detail below.
Where non-surgical approaches typically fall short is in cases of significant excess skin, pronounced vertical bands, or severe sagging after major weight loss. These usually require surgical procedures for a noticeable correction.
If you’ve just noticed a bit of lax skin under your chin, you can try some at-home methods first. But keep in mind that firstly, they don’t produce immediate results, so you’ll have to be consistent, and secondly, they won’t physically remove any excess skin. These methods can only help you support your skin’s health. Some of them can also stimulate and support collagen production.
The most evidence-supported ingredients for improving skin texture and encouraging collagen production in aging skin are retinoids, peptides, antioxidants, niacinamide, and hyaluronic acid:
None of these ingredients will reverse significant laxity on their own. But used consistently, they can slow the rate of degradation and keep your skin in better condition to respond to clinical treatments.
You’d be surprised how many people apply SPF on their faces every two hours and almost never apply it to the neck area as well! So, whatever you use on your face (moisturizers, serums, masks), apply it down the neck and under the chin too. This includes SPF, which is non-negotiable given what sun exposure does to collagen over time.
Apply the products in upward strokes on the neck, not downward ones. This is a very important detail because applying products downward can actually make skin laxity worse.
Sun exposure and smoking have been covered above. Beyond those, try to avoid rapid weight changes. Yo-yo dieting repeatedly stretches and loosens the neck skin, which is not favorable for it. On that account, maintaining a healthy weight can help reduce and prevent skin laxity on the neck.
Also, sagging skin on the neck can be caused or worsened by long hours looking down at screens, dehydration, chronic poor sleep, stress, and diets that are low in protein (which is needed for collagen synthesis). Therefore, try to eat a healthy diet with adequate protein and antioxidants and maintain a healthy lifestyle. This supports your skin from the inside.
Neck and chin exercises may help tighten loose skin… a little. They can help strengthen and tone neck muscles, but they won’t remove excess skin or address the loss of elasticity.
Popular neck exercises include:
These exercises can improve muscle tone in the neck muscles. Better muscle tone does contribute to a slightly firmer appearance. Strengthening the postural muscles also reduces tech neck positioning, which has indirect benefits for how the neck looks and feels. Regular massages of the chin area can also help improve blood circulation and reduce fluid buildup, potentially firming the skin over time.
What these exercises cannot do is remove loose skin and reduce submental fat cells. They also cannot address the structural collagen changes that cause significant laxity. Toning the underlying neck muscles can slightly lift the tissue. But if there is meaningful excess skin, no amount of chin lifts will eliminate it. So, neck exercises may be worth doing for posture, for muscle tone, for overall neck health.
All non-surgical treatments that can help tighten the skin under your chin have different mechanisms of action. The right choice depends on your anatomy, skin quality, and the specific nature of your concern.
Radiofrequency is a non-invasive procedure. RF devices deliver controlled heat energy into the deeper layers of the skin. There, it stimulates collagen and elastin remodelling. The heat causes existing collagen fibres to contract. This triggers the production of new structural proteins over the following weeks and months.
RF treatments are well established for the jaw and neck area, with a good safety profile across skin tones. Results are gradual, typically requiring multiple sessions, and maintenance treatments help sustain them. Downtime is generally minimal.
Focused ultrasound devices target the deeper structural layers beneath the skin, including the SMAS (superficial musculoaponeurotic system). This is the same layer addressed during surgical neck lift procedures. By delivering precise thermal energy to these deeper layers, ultrasound treatments aim to produce a lifting effect. They are best suited to mild to moderate laxity and work slowly, with results continuing to improve over three to six months post-treatment. Downtime is low, though some people experience temporary discomfort or swelling.
Nitrogen plasma technology delivers controlled thermal energy to the skin. This triggers resurfacing and collagen remodelling simultaneously. Unlike many other energy-based treatments, plasma devices address both the texture of the skin and the bigger structural changes that contribute to laxity. For the neck area, this means it can help improve crepey texture and mild to moderate skin laxity in staged treatments.
Neogen, for example, uses nitrogen plasma specifically, delivering a different thermal profile and tissue response. There is downtime involved, though, particularly with more aggressive settings, and results develop progressively. But still, the treatment is less aggressive than ablative lasers, and the downtime is less significant.

Fractional laser treatments and non-ablative laser or light technologies can help stimulate collagen production and improve skin texture across the lower face and neck. Ablative lasers produce more significant results but come with more downtime (a few weeks). Non-ablative options are gentler and have less recovery time. The appropriate choice depends on skin type, laxity severity, and how much downtime is acceptable.
Standard microneedling creates controlled micro-injuries that trigger the skin’s repair response, including increased collagen synthesis. RF microneedling combines this with radiofrequency energy delivered via the needles into the deeper dermis. This amplifies the collagen-stimulating effect. Both can be used for laxity, skin texture, and skin tone in the lower face and jawline area. Multiple sessions are standard. Downtime is typically a few days of redness.
Products like poly-L-lactic acid (Sculptra) and calcium hydroxylapatite (Radiesse) are collagen-stimulating injectables. They work over months to rebuild structural support in the lower face and jawline. They do not fill volume like dermal fillers do, though. Instead, they encourage the skin to produce more of its own collagen. Results appear gradually and can last one to two years.
Dermal fillers aren’t usually used to address skin laxity directly, but they can still be of help. Hyaluronic acid fillers placed along the jawline and chin area can improve the definition of the jaw’s edge. This can make the lower face look sharper and reduce the visual impact of early jowling. Fillers basically reshape the structural frame beneath the skin. They’re often combined with other tightening treatments for a more complete result.
Dissolvable threads (PDO or PCL) inserted under the skin can physically lift soft tissue. Over the following months, they can stimulate localised collagen production as the threads dissolve. They are best suited to mild to moderate sagging and early jowling rather than significant laxity. Results last one to two years typically. Thread lifts are a minimally invasive treatment, with some bruising and swelling expected post-procedure.
Many clinics now use platforms that combine multiple technologies in a single device or protocol, targeting the neck and chin from several angles at once.
T-Shape 2 is an RF-based platform that combines radiofrequency energy with low-level laser, vacuum massage, and mesospheric activation. This unique combination can help address skin laxity, enhance blood circulation, improve tone, and support lymphatic drainage. This non-invasive treatment may also be recommended for overall neck and facial rejuvenation, and it can support neck fat loss as well. It requires minimal downtime, and the procedure feels like a warm massage.

In some cases, non-surgical options aren’t helpful enough. Significant skin laxity, pronounced neck bands, major post-weight-loss excess skin, or a combination of these typically requires cosmetic surgery.
A neck lift surgery, for example, (platysmaplasty or cervicoplasty, depending on what is being addressed) can directly remove excess skin, tighten the platysma muscle, and reshape the neck contour. Neck liposuction might be recommended if you’re dealing with neck fat.
Results vary depending on the treatment type, the individual’s skin, and whether maintenance is kept up.
Non-surgical tightening treatments like RF, ultrasound, and plasma work by stimulating the body’s own collagen production. That collagen takes time to build and time to degrade. Most people see visible results 3-6 months after a treatment course. The results last roughly 1-2 years before a maintenance session is needed. Skin cell turnover and ongoing collagen production are continuous biological processes, and periodic treatments help sustain the response.
Surgical results last longer. A neck lift performed in the mid-forties may provide a decade or more of sustained improvement before the effects of ongoing aging become visible again.
Start with the question of what you are actually trying to address. Is the main concern submental fat, a double chin, or fullness? Loose skin, sagging, or crepey texture? Neck bands? Or a combination?
Try a self-assessment test. If you pinch the skin under your chin and it snaps back readily, skin elasticity is probably good, and fat reduction may be sufficient. If the skin feels thin, loose, or crinkled, skin tightening is the priority. If you can see or feel vertical bands running down the front of the neck, those are platysmal bands, which respond best to Botox injections.
When you’re consulting a practitioner, ask specifically about their experience treating the neck and jawline area. Ask to see before-and-after photographs from clients with similar concerns and skin type to yours. Ask which technologies they use and why those are appropriate for your anatomy. Be wary of any provider who gives a definitive treatment recommendation before properly assessing your neck in person and your medical history.
Because of the anatomical complexity of the neck area, generalist treatment protocols aren’t recommended. Any assessment and any treatments should be performed by a qualified medical professional with relevant training and experience.

The right approach depends on whether you’re dealing with fat, loose skin, or both. Submental fat responds well to injectable fat-dissolving treatments or non-surgical fat reduction, while loose skin needs collagen-stimulating treatments like radiofrequency or plasma resurfacing. For a combination of the two, most practitioners recommend pairing a fat reduction method with a skin-tightening treatment.
No household item will noticeably tighten crepey skin. Most DIY remedies that are popular online produce no lasting structural change. What you can do at home is apply a retinol or peptide moisturiser consistently to the neck area and use SPF daily, both of which support collagen production and slow further deterioration over time.
Mild to moderate saggy skin can improve significantly with the right clinical treatments: radiofrequency, ultrasound, and plasma resurfacing, for example. Significant sagging, particularly after major weight loss or in older skin, may require a surgical approach.
