Radiesse (Mertz Co) has been used as a great filler for a very long time, I’ve been injecting it since 2006. Some like to call it “injectable implant” because you can get a filling effect similar to putting a small silicone implant in. Radiesse has 2 components in it – one is a liquid filler, which works immediately upon contact with tissues it is injected into, and the second one is microcrystals of Calcium Hydroxyapatite (CaHA – a substance similar to what bones are made of). These microcrystals work over time by stimulating the tissues to produce collagen and elastin. When Radiesse is diluted (1:1) or hyperdiluted (1:2 – 1:6), the filler does not create as much of volumizing effect, but the CaHA does the work on a larger scale. This is why it is used to significantly reduce wrinkles and skin irregularities.
Hyperdilute Radiesse can be injected pretty much everywhere in the body where skin laxity, wrinkles or cellulite are present – neck and decolletage, face, upper arms, knees, thighs, etc. It’s best to do two treatments about 4 months apart, to get great results 4-7 months later. Of course there would be some evening out immediately after the injections, but that’s not what you expect from the treatment – the CaHA didn’t even start working at that time yet, you are only seeing the filler effect, which obviously mild because of hyperdilution.
Studies have shown a significant increase in the amounts of collagen and elastin in the skin where hyperdilute Radiesse was injected. Most specialists use cannula to inject instead of a sharp needle, and that help reduce any undesirable side effects, such as bruising and bleeding. The use of cannula also helps distribute the medication to a larger surface area, especially on legs where varicose veins are often present, and can limit the reach when needles are used.
Overall the procedure is very safe and effective.
