Dermal Fillers

What are Dermal Fillers?

Dermal fillers (injectable fillers) are used to refine and improve the appearance of the skin and treat volume loss.  They can smooth lines and wrinkles or be used to add volume and ‘plump up’ the skin by filling contours. Dermal fillers are especially popular to add volume to the middle face and create a fuller appearance.


What is Hyaluronic Acid?

Hyaluronic acid is a substance that occurs naturally in the human body and it works by acting as a cushion and lubricant in the joints and other tissues. Hyaluronic acid binds water in the skin, thereby increasing hydration and volume – hence its use as a dermal filler.

Natural hyaluronic acid is broken down by the body in one or two days so is constantly replaced. As we age this replacement mechanism diminishes so the moisturising and plumping effects of hyaluronic acid decrease.

The hyaluronic acid used in aesthetic medicine is produced in a laboratory, in most cases using bacterial fermentation rather than being animal-derived.


What areas can be treated with dermal fillers?

 Dermal fillers are commonly used to treat various cosmetic concerns, including:

  • Smoothing out lines and wrinkles, such as nasolabial folds (nose to mouth lines), marionette lines, and vertical lip lines.

  • Enhancing and restoring volume to the cheeks or temples.

  • Plumping and enhancing the lips.

  • Filling in under-eye hollows or tear troughs.

  • Correcting chin or jawline contours.

  • Softening acne scars or other facial depressions.


How do dermal fillers work?

Dermal fillers are injected into the skin to replenish lost volume and stimulate collagen production. The filler material fills in wrinkles, lines, or hollow areas, giving a smoother and more youthful appearance. Hyaluronic acid fillers also attract and retain water, providing hydration and improving skin elasticity.


How soon will I see results?

Results are immediately visible, although the treated area will swell and can often bruise - this is completely normal and will settle within 3-7 days. It typically takes up to 14 days to fully appreciate the effects. Dermal fillers stimulate the production of collagen, meaning results may continue to gradually improve for several weeks following treatment.


 How long do Dermal Fillers last?

The longevity of dermal fillers depends on the type of filler used and individual factors. On average, hyaluronic acid fillers can last from six months to two years. Over time, the body gradually breaks down and absorbs the filler material. To maintain the desired results, repeat treatments are needed. 


 Is the procedure painful?

Most dermal fillers contain a local anesthetic called lidocaine, which helps minimize discomfort during the procedure. Additionally, a topical numbing cream may be applied before the injections. Some patients may still experience mild discomfort or a pinching sensation during the injections, but it is generally well-tolerated.


What should I do after treatment with dermal fillers?


After treatment, please avoid alcohol consumption and applying make up for 24 hours. Please avoid extreme sun exposure, UV light, temperatures below 0°C, saunas and steam rooms for 2 weeks after treatment. It is advisable to avoid strenuous activity or exercise for up to 24 hours and to avoid massaging the treated area. Try to sleep with the head elevated and avoid sleeping on the injected areas for one or two days.



Bleeding, bruising, lumps, bumps or nodules may appear at the injection site. Very rarely, cases of discolouration or lightening at the injection area have been reported.


Are dermal fillers safe?

Dermal fillers are generally considered safe when administered by a qualified and experienced professional. However, there are risks associated with any medical procedure. Common side effects may include bruising, redness, swelling, lumps or nodules or tenderness at the injection site. Serious complications are rare but can occur if the filler is injected incorrectly or if there is an allergic reaction. Rare cases of necrosis (cell death), abscesses (collection of pus), granulomas (foreign body reaction) and immediate or delayed hypersensitivity (allergic reactions) have also been reported after dermal filler injections.


 I am a suitable candidate for dermal filler treatment?

Dermal fillers are generally safe for many people, but there are certain contraindications and precautions. Individuals who are pregnant, breastfeeding, have active infections or inflammation at the treatment site, or have a history of severe allergies should avoid dermal filler treatment. It’s important to seek professional advice from a qualified healthcare professional to assess your individual needs and determine the most appropriate treatment option for you.
