Dermal Fillers Risks and Safety

Below is information on the most commonly used dermal fillers, where they can be used and some associated side effects.

Hyaluronic Acid

The most popular dermal fillers consist of a material called hyaluronic acid. This material is found in all of our bodies — therefore, most people tolerate this dermal filler quite well, with no associated side effects. Hyaluronic acid can be processed in various ways, giving your injector the ability to manipulate the amount of volume, thickness, and the longevity of the effects on your skin.

Hyaluronic acid fillers come in several different forms including; Volbella, Juvederm, Restylane and much more… Your cosmetic injector will advise on using certain types of hyaluronic acid fillers dependent on the treatment area, experience, your preference and desired outcome.

Side Effects of HA

Swelling is the most common side effect. Most people experience swelling in the first 24 hours following their injections, followed by a significant reduction.

The following tips will help minimise swelling during the first day following facial injections:

  • Avoid touching the injected area
  • Cut back on your salt and alcohol intake
  • Apply a cold compress on the injection area
  • Ensure that your head is elevated while resting

If you experience any significant redness, itching or swelling at the injected areas, contact your cosmetic injector. The most prominent benefit to Hyaluronic Acid dermal fillers is that with another enzyme injection, they can be dissolved, which makes the filler reversible.

Other Types of Dermal Fillers

Hyaluronic acid fillers are the most commonly used; however, there are other fillers used for specific treatment areas:


Radiesse is a temporary thickener made of calcium hydroxyapatite. It is not dissolvable and lasts much longer than hyaluronic acid fillers. Your cosmetic injector may advise on using Radiesse for deeper injection in areas like the nasolabial folds and deep temple and cheek injections. One possible risk is injection into a blood vessel, which can cause severe complications. In some situations, injections with Radiesse that are made too close to the surface of the skin can lead to lumpiness underneath the skin. However, when utilised correctly, by skilled cosmetic injectors like at London Cosmetic Clinic who are specialised in cosmetic injectables, this dermal filler can be very beneficial for providing volume and decreasing deep folds.


Sculptra is a collagen-stimulator filler designed for individuals who need to add volume in larger areas gradually. Before the injection, the Sculptra solution is hydrated with water for two days. It’s then injected in tiny doses throughout the tissues underneath the skin in the desired area. Most people start to see the full results between three to six weeks. Benefits include a gradual increase in volume and a more natural-appearing result.

Which Dermal Filler is Right for You?

A skilled cosmetic injector with experience in treating the face can help you choose the best dermal filler treatment for you. The optimal dermal filler product to use depends on the depth of the tissue, the area and the thickness of the material.
