Not all fillers are equal!

Patients often ask how much is 1ml of filler?

Hyaluronic Acid

Most of the fillers are HA (hyaluronic acid). This is a naturally occurring substance which is present as a kind of padding within the body. The purchase cost of fillers varies significantly. This is because fillers from the top manufacturers have been heavily researched so we understand their behaviour and are made to exacting standards. Cheap fillers may contain substances that are not sterile or cheaper such as hair gel. This makes reaction to fillers more likely.

Different Characterisitics

Fillers have different  characteristics and it is for this reason that we stock a wide range of fillers in our clinics. The key elements are elasticity, viscosity and cohesiveness.

Elastic fillers bounce back and maintain projection. Viscosity allows a filler to remain where it is placed and not spread. Cohesiveness allows a filler to stay together potentially creating a smoother result. Highly elastic and viscous fillers tend to be easier to feel and last longer so are placed deeper.

If you are trying to project a chin for instance a highly viscous and elastic filler would be best. This because it stays where it is and pushes the tissue upwards. For a fine wrinkle you require the opposite something that spreads, is easily mouldable and does not project. Cohesiveness makes it smoother when placed close to the surface. . For lips you might want something similar with perhaps a little more projection. For volume replacement in the lower face you require moderate viscosity and elasticity so it spreads enough and you cannot feel it.

There are other factors such as cross linking which affect how a filler behaves.

Cost comparisons not straightforward

This is why extensive experience and scientific understanding of different fillers is essential. Cost comparisons of 1ml of filler are as relevant as comparing red cars i.e they are all red but there is a vast difference between a red Ferrari, Range Rover and Mini.
