Dermal Fillers

Injectable gels placed precisely into the skin or deeper tissue to restore lost volume, smooth lines and folds, enhance facial features, and improve the overall quality and structure of the face.

What Are Dermal Fillers?

Dermal fillers are injectable products used to add volume, smooth lines, enhance features, or improve skin quality in specific areas of the face. The vast majority of fillers used in aesthetic practice today are made from hyaluronic acid, a substance that occurs naturally in the body and plays a key role in keeping the skin hydrated and supported. When injected, hyaluronic acid gel attracts water and integrates with the surrounding tissue, adding volume and structure in a way that feels soft and natural.

Fillers are used across a wide range of facial areas and concerns. Common applications include restoring volume to the cheeks and temples as it diminishes with age; softening deep folds such as the nasolabial folds that run from the nose to the corners of the mouth; adding definition and projection to the jawline and chin; enhancing the lips; filling the hollow under the eyes; and improving the overall quality and hydration of the skin through skin booster injections. The specific product, technique, and amount used varies considerably depending on the area and the goal.

Hyaluronic acid fillers are temporary. The body gradually breaks them down over a period of months to a couple of years, depending on the product used and the area treated. A key advantage of hyaluronic acid fillers is that they can be dissolved relatively quickly using an enzyme called hyaluronidase if the result is not as expected, if a complication arises, or if the individual simply changes their mind. This reversibility makes them among the safest and most widely used injectable products in aesthetic medicine.

What to Expect

Dermal filler treatment begins with a consultation to discuss goals, assess facial anatomy, and determine the most appropriate approach. Most providers apply a topical numbing cream to the treatment area beforehand, and most filler products also contain a small amount of local anaesthetic that further reduces discomfort during injection.

The filler is injected using either a fine needle or a blunt-tipped cannula, which is a thin flexible tube used to deposit the product more broadly with fewer entry points and often less bruising. The choice of technique depends on the treatment area and the provider’s preference. The procedure typically takes between 15 and 45 minutes depending on the number of areas treated.

After treatment, some swelling and occasional bruising in the treated areas is normal and settles within a few days to a week. The lips tend to swell more than other areas and the initial result may look more pronounced than the final outcome. Most results are fully settled and representative at two weeks. There is no significant downtime, and most people return to their normal activities the same day, though strenuous exercise and significant heat are usually avoided for the first 24 hours.

Who It’s For and Results

Dermal fillers are suited to a wide range of people and goals. Those experiencing age-related volume loss in the face benefit from structural restoration that can lift and reposition tissue as well as add volume. Younger people seeking to enhance features they were born with, such as adding definition to the jawline or projection to the chin, are also appropriate candidates. Fillers are suitable from the mid-twenties onward and are relevant across a broad age range rather than being exclusively associated with older clients.

The most natural-looking results come from a conservative approach that enhances and restores rather than overfills. Working with a provider who understands facial anatomy and proportion and who takes a measured approach to the amount of product used is the most important factor in achieving an outcome that looks and feels right.

Results from hyaluronic acid fillers typically last from six months to two years depending on the product formulation, the area treated, and how the individual metabolises the product. Areas of high movement such as the lips tend to break down filler more quickly than structural areas such as the cheeks or jawline. Maintenance treatments before the filler has fully broken down help sustain a consistent result over time.

Frequently Asked Questions: Dermal Fillers

Hyaluronic acid dermal fillers have a strong safety profile when used by qualified and experienced providers. They are temporary, reversible, and made from a substance that occurs naturally in the body. Serious complications are rare but can occur, particularly if injections are placed in or near blood vessels. This is why choosing a qualified provider with a thorough understanding of facial anatomy is the most important safety measure. The ability to dissolve hyaluronic acid filler quickly with hyaluronidase is an important safety backstop that distinguishes it from permanent fillers, which carry significantly higher risk.

Unnatural-looking results are almost always the product of too much filler being used, product being placed in the wrong areas, or repeated treatments without adequate assessment of what has already been placed. With appropriate amounts, good technique, and a conservative approach, filler produces results that look like a more rested or refreshed version of the individual rather than obviously altered. The key is choosing a provider whose aesthetic judgement aligns with the individual’s goals and who is willing to use restraint.

Yes. Hyaluronic acid filler can be dissolved using an enzyme called hyaluronidase, which breaks down hyaluronic acid relatively quickly. The dissolving process typically produces results within 24 to 48 hours. This reversibility is one of the most significant advantages of hyaluronic acid fillers and is a meaningful safety net for both clients and providers. It does not apply to non-hyaluronic acid fillers such as calcium hydroxylapatite products, which cannot be dissolved and must be allowed to break down naturally over time.

Fillers and anti-wrinkle injections are both injectable treatments but they work in completely different ways. Anti-wrinkle injections contain botulinum toxin, which temporarily relaxes the muscles responsible for expression lines, reducing the appearance of dynamic wrinkles caused by movement. Dermal fillers add physical volume and structure to specific areas, addressing static lines, volume loss, and feature enhancement. The two treatments are often used together as part of a comprehensive approach, with each addressing aspects of facial ageing or aesthetics that the other cannot.
