Soft Tissue Fillers
Soft tissue filler treatment refers to the use of injectable gel-like substances, most commonly hyaluronic acid-based products, to restore lost facial volume, enhance contours and improve the appearance of static wrinkles. These treatments are widely used to address age-related volume loss in areas such as the cheeks, lips, under-eyes and jawline.
Unlike neurotoxin, which works by relaxing muscle activity, soft tissue fillers work by replacing or augmenting volume beneath the skin, helping to support facial structures and restore smoother, more youthful contours.

Temporary and Permanent Options
Soft tissue fillers can be broadly divided into temporary, longer-lasting (semi-permanent) and permanent options, depending on the material used and how the body interacts with it.
Temporary fillers are the most commonly used in modern aesthetic practice. These are typically made from hyaluronic acid, a naturally occurring substance in the skin. They are gradually broken down by the body over time and can be adjusted or reversed if needed. Temporary fillers are preferred for most facial areas because they allow for flexibility, refinement and a lower long-term risk profile.
Longer-lasting or semi-permanent fillers are designed to persist for extended periods, often by stimulating collagen production or using more durable materials. While they may reduce the need for repeat treatments, they are used more selectively due to reduced reversibility and a higher requirement for precise placement and patient selection.
Permanent fillers are rarely used in contemporary facial aesthetic practice due to the difficulty in reversing results and the potential for long-term complications. In most cases, modern treatment strategies favour temporary fillers because they offer greater safety, adaptability and control over long-term outcomes.
Fat grafting (autologous fat transfer) is also considered a permanent volume restoration option. In this procedure, fat is harvested from another area of the patient’s body (such as the abdomen or thighs), processed, and then carefully injected into areas of facial volume loss. Once the transferred fat establishes a blood supply, a portion of it can survive long-term, making it a more durable and natural alternative to synthetic fillers. Fat grafting is often used for patients seeking longer-lasting or permanent facial volume restoration, particularly in the cheeks, temples, under-eye region and jawline.
Indications for Soft Tissue Fillers
As the face ages, natural fat pads shift and diminish, bone structure gradually resorbs and skin elasticity decreases. These changes can lead to hollowing, sagging and the development of deeper folds.
Soft tissue filler treatment may be considered for:
- Loss of cheek volume and midface flattening
- Tear trough hollowing under the eyes
- Nasolabial fold (lines from nose to mouth)
- Marionette lines and downturned mouth corners
- Lip volume loss or asymmetry
- Chin augmentation and projection
- Jawline definition and contouring
- Temples hollowing
- Hand rejuvenation in select cases
In many patients, multiple areas are treated together to restore overall facial balance and proportion.
Treatment Areas and Techniques
Soft tissue fillers are placed beneath the skin using fine needles or cannulas, depending on the treatment area and desired outcome. The choice of product, depth of injection and technique are tailored to each patient’s anatomy and aesthetic goals.
Common treatment regions include:
- Midface - restoration of cheek volume and support of lowe facial tissues
- Tea troughs - reduction of under eye hollowing and shadowing
- Lips and perioral region - enhancement of shape, hydration and symmetry
- Lower face - softening of marionette lines and improvement o jawline contour
- Chin and jawline - enhancement of projection and definition
- Temples - correction of hollowing for improved facial balance
Fat grafting techniques may be used in similar regions but typically involve deeper structural placement and are often selected for patients seeking longer-term or permanent volume restoration.
Precise placement is essential to achieve natural-looking results while avoiding overcorrection or distortion of facial proportions.
What Can Soft Tissue Fillers Achieve?
Soft tissue filler treatment can:
- Restore lost facial volume and youthful contours
- Soften static lines and deep facial folds
- Improve facial symmetry and balance
- Enhance lip shape, hydration and definition
- Strengthen jawline and chin projection
- Reduce the appearance of under-eye hollows
- Provide subtle lifting effects by supporting facial structures
Fat grafting can achieve similar goals with the added benefit of potentially long-term or permanent volume restoration, particularly in patients with more significant age-related volume loss or those seeking a more durable solution.
The goal is not to create exaggerated features, but to restore natural volume loss and enhance facial harmony while maintaining individual identity and expression.
Preparing for Treatment
Soft tissue filler treatment is suitable for most healthy adults seeking improvement in facial volume loss or contour irregularities. A detailed facial assessment is performed to evaluate anatomy, symmetry and treatment priorities.
Patients may be advised to avoid blood-thinning medications or supplements prior to treatment to reduce the risk of bruising. Alcohol consumption should also be minimized before injections when possible.
For fat grafting procedures, additional planning is required, including assessment of donor sites and discussion of a surgical procedure rather than a simple injectable treatment.
Recovery and Risks
Recovery after soft tissue filler treatment is typically minimal. Most patients resume normal activities immediately, although mild swelling, redness, tenderness or bruising at injection sites may occur temporarily.
Results are visible immediately, although final appearance may take several days once swelling settles. Depending on the product used, treatment effects typically last between 6 and 18 months, with variation based on area treated, metabolism and product type.
Fat grafting has a longer recovery period, as it involves both a donor site and treated facial areas. Swelling may take several weeks to fully settle, and final volume stabilisation can take several months as the transferred fat integrates.
Potential risks include bruising, swelling, asymmetry, lumpiness, overcorrection, undercorrection, vascular occlusion (rare but serious), infection and temporary changes in skin texture or sensation. Fat grafting carries additional considerations such as partial fat resorption, contour irregularities at donor or recipient sites, and variability in long-term fat survival.
Soft tissue filler treatment is ultimately focused on restoring youthful facial volume and structure by carefully replacing lost support, improving contour and enhancing facial harmony while maintaining a natural and balanced appearance.
