Understanding Your Options
Skin laxity is a natural part of ageing, shaped by genetics, cumulative sun exposure, and time. As these changes become noticeable on the face and body, many people begin exploring ways to address changes in skin firmness without committing to surgery.
Two commonly considered non-surgical options are laser skin tightening and thread lifts. While both aim to address loose skin, they work through fundamentally different mechanisms. Laser treatments such as the 4D Skin laser use controlled heat energy to stimulate collagen production beneath the skin’s surface. Thread lifts, by contrast, use dissolvable sutures inserted beneath the skin to mechanically lift tissue and initiate the body’s natural healing response.
Understanding how each method works can help you approach your consultation with more considered questions.
How Laser Skin Tightening Works
Laser skin tightening uses focused light energy to warm the deeper layers of skin, specifically the dermis. When sufficient heat is delivered to this layer, two things may occur:
- Existing collagen fibres may contract in response to the heat.
- The body may receive a signal to begin producing new collagen over the following weeks.
The technology is designed to target deeper skin layers while preserving the surface, which is why downtime is often minimal — though individual recovery varies. Most people are able to resume daily activities within a period of time that varies by individual.
Because results depend on new collagen formation, changes develop gradually over several weeks to months rather than appearing immediately.
How Thread Lifts Work
Thread lifts involve the insertion of dissolvable medical threads beneath the skin using thin needles. When correctly positioned, the small barbs or cones on each thread grip surrounding tissue and lift it into a repositioned position.
The threads serve a dual function:
- They mechanically reposition sagging tissue by anchoring it to more stable areas.
- They stimulate the body’s healing response, prompting collagen production around the thread insertion sites.
The procedure is performed while the patient is awake, with a topical or local numbing agent applied beforehand. It is completed in a single session and involves smaller entry points than surgical alternatives.
Thread lift results are typically temporary, lasting approximately one to three years depending on individual factors. As the threads dissolve and are absorbed by the body, the lifting effect gradually diminishes.
Comparison Overview
Factor | Laser Skin Tightening | Thread Lift |
Treatment Approach | Uses controlled heat energy to stimulate collagen activity in deeper skin layers | Uses dissolvable medical threads placed beneath the skin to reposition tissue and stimulate collagen response |
Invasiveness | Non-invasive (no insertion beneath the skin) | Minimally invasive (involves insertion of threads beneath the skin) |
Sessions | Usually performed over multiple sessions | Commonly performed in a single session |
Onset of Results | Changes develop gradually over several weeks as collagen activity increases | A structural lifting effect may be observed earlier, with ongoing collagen response over time |
Recovery | Temporary redness or mild swelling may occur | Temporary bruising, swelling, or mild discomfort may occur |
Duration of Effect | Varies depending on individual collagen response and maintenance | Threads dissolve over time; effects gradually reduce as threads are absorbed |
Maintenance | Periodic sessions may be recommended | Repeat procedure may be considered after threads dissolve |
Suitability | Often considered for mild to moderate skin laxity | May be considered for mild to moderate sagging requiring structural support |
What to Expect from Each Procedure
What to Expect from Each Procedure
Laser treatments are typically delivered across multiple sessions spaced several weeks apart to stimulate collagen production over time. Each session generally lasts between 30 and 60 minutes, depending on the area being treated.
During treatment, patients may experience a sensation of warmth or mild heat. Most people are able to tolerate this without strong pain relief. Post-treatment effects are usually mild and may include:
- Temporary redness
- Minor swelling
These effects typically resolve within a short period.
What to Expect from Each Procedure
Thread lifts are performed in a single session lasting approximately one hour, though the duration may vary depending on the number of threads used and the areas being treated. A numbing agent is applied prior to the procedure.
Common post-procedure effects include:
- Bruising
- Swelling
- Mild discomfort
- Small dimples or slight surface irregularities (typically temporary)
These effects are generally short-lived and improve as healing occurs.
Things to Consider Before Deciding
Several factors may influence which approach is more appropriate for your situation:
- Degree of skin laxity: Mild to moderate laxity responds differently to each treatment compared to more pronounced sagging.
- Skin type: Certain skin types may respond differently to heat-based treatments than others.
- Medical history: Conditions affecting bleeding or wound healing may make thread procedures less suitable.
- Recovery time: The duration of recovery may differ between the two procedures, and varies between individuals.
- Longevity of results: Laser outcomes depend on ongoing collagen activity. Thread lift effects gradually reduce as threads dissolve, with repeat procedures typically considered after one to three years.
- Cost structure: Laser treatments require multiple sessions, while thread lifts are performed in one sitting but may need to be repeated every few years.
Doctor’s Perspective “Having realistic expectations about what these procedures can and cannot achieve is an important part of the decision-making process. Begin with a consultation in which you can openly discuss your concerns, review expected outcomes, and examine relevant educational materials. Keep in mind that results depend on appropriate patient selection and the experience of the practitioner — seek a professional who takes the time to understand your individual goals.” |
Choosing Wisely
Laser skin tightening and thread lifts are both non-surgical approaches to addressing changes in skin firmness and contour. Neither is permanent, and neither replicates the degree of change achievable through surgery.
The appropriate option depends on your skin type, the extent of laxity, your available recovery time, and your personal circumstances. A qualified medical professional can assess your specific situation and outline what either procedure may or may not achieve for you.
Understanding the differences between these two options can help you ask more considered questions during your consultation and determine whether the potential outcomes align with your goals.

Choosing Wisely
Are these procedures painful?
Most patients are able to tolerate laser treatments without strong pain relief. The sensation is often described as warmth or a mild snapping feeling. Thread lifts are performed with local anesthetic, so sharp pain is not expected, though a sensation of pressure or pulling during the procedure is normal.
How long will it take to see results?
Thread lift patients may notice a structural lifting effect within a period that varies by individual. Visible changes may become more apparent once initial swelling subsides — typically within one to two weeks. Laser treatment results develop gradually, as new collagen forms over a period of two to six months.
Can both procedures be performed together?
Yes. Some patients opt for a combined approach to address both structural lifting and collagen stimulation. A qualified practitioner can advise whether this combination is appropriate for your skin type and goals.
Will the results look natural?
Both procedures aim to produce changes in appearance that are proportionate to the degree of laxity being addressed. The extent and appearance of results vary by individual and depend on a range of factors, including skin condition and the areas treated.
How do I decide between the two?
Begin with a consultation with a qualified professional who can assess your skin and discuss your concerns in detail. Based on your skin type, lifestyle, and goals, they can outline which option — or combination — may be worth considering.
