Radiesse Hyper Dilute

Got wrinkles, fine lines, skin laxity, thinning skin, or neck lines?  Then you may be a candidate for skin rejuvenation treatment with Hyperdilute Radiesse!

What is Radiesse?

Radiesse was approved by the FDA as a facial filler at the end of 2006 and has been used as a volumizing filler since.  Radiesse consists of calcium hydroxyapatite (CaHA) microspheres suspended in an aqueous polysaccharide gel carrier.  Once it is injected, the gel is absorbed over time.  The body then metabolizes the CaHA microspheres, which stimulate the body to produce collagen.

In recent years, the use of Radiesse in a hyperdiluted form has increased.  In this form, it is a biostimulatory agent, rather than a volumizing filler, and it improves skin quality, texture, tone and firmness.  It can be used in the face, neck, décolletage and other areas of the body.  This technique was first used in Europe, yet it’s now being used more and more in the U.S.

What is Hyperdiluted Radiesse?

Hyperdiluted Radiesse is simply Radiesse that has been diluted / thinned out, with a mixture of sterile saline solution and lidocaine.  This makes it an easily spreadable biostimulator capable of remodeling skin over a larger area.

When this diluted mixture is injected into areas of collagen loss, it triggers the body to produce new collagen and elastin. The result is a skin rejuvenating treatment with pronounced and visible smoother, firmer, younger-looking skin.

The benefits of this treatment are skin tightening and thickening, reducing the appearance of fine lines, wrinkles, and crepiness.  Treatment of the décolletage will also reduce the pigment from sun damage. Overall, skin tone, texture and elasticity are markedly improved.

Where can it be used?

  • Mid and lower face
  • Neck lines and/or neck in patients with mild to moderate laxity
  • Décolletage
  • Buttocks with cellulitic dimples (in patients with moderate to severe cellulite) to reduce the appearance of dimpling
  • Above knees to address the knee lines from lax skin with aging

How much diluted Radiesse is needed?

Radiesse is available by the syringe, and, according to the current practice guidelines, treatment typically requires one syringe per area. The face and neck each usually require a single 1.5cc syringe per session, while the chest requires a half to a full syringe.

What is the downtime?

As with any filler injection, there can be some bruising, swelling and mild discomfort after the treatment.  Most clients tolerated this treatment well and are very satisfied with their results.

There can be a variable amount of bruising and swelling, which normally lasts up to a week.

How many treatments are needed?

One to three treatment sessions are usually required to achieve the desired aesthetic effects.  Two treatments are typical, though severe sun damage or severe skin laxity may require more.

These treatments are spaced out one month apart.  Though preliminary research shows that results with hyperdiluted Radiesse may last up to two years.  one will likely want to have one hyperdilute Radiesse treatment every 12 to 18 months for maintenance.

Combination Therapy

Hyperdiluted Radiesse can be used alone.  Yet when addressing areas with harder to treat concerns, such as the neck or chest, it is best to treat in combination with other tightening and resurfacing procedures, such as microneedling, because they work together to improve dermal collagen.

How Radiesse Works



  • How long does a treatment take? Is there any downtime? 

In experienced hands, the treatment takes about 20-30 minutes, depending on the areas treated. You will experience some swelling of the treated areas for a few days. There is no downtime and you can return to normal activity right away, although it is recommended not to do any facial massages for 1-2 weeks until the product has settled into the skin

  • Is the treatment painful?

This treatment is not painful, only mildly uncomfortable from the injection. A topical local anaesthetic will be applied prior to treatment. In addition, Radiesse PLUS contains 0.3% of lidocaine, a local anaesthetic.

  • Who should not go for this treatment?

This treatment is not recommended for women who are pregnant or breastfeeding, or those with open wounds on the skin. 

  • How is this treatment different from fillers such as Juvederm/Restylane? 

Most fillers on the market are made from hyaluronic acid- they act by volumeizing the treated areas. The results typically last for 9-12 months and annual treatments are recommended. 

For patients who are receiving fillers for the first time- it is better to start with a hyaluronic acid filler, which can be reversed. For those who have received fillers before and liked the result, and are seeking a longer lasting (and more value for money!) treatment, then Radiesse would be ideal.

  • How is Radiesse different from Sculptra or Ellanse?

These 3 injectable fillers are similar in many ways- they are long lasting (>1 year) filler treatments that provide volume restoration as well as collagen stimulation. There are slight differences- the active compound is different- Radiesse contains CaHa (Calcium Hydroxyapatite) in a CMC (CarboxyMethylCellullose) gel, Ellanse contains PCL (Polycaprolactone) in a CMC (CarboxyMethylCellullose) gel and Sculptra contains PLLA (Poly-L-Lactic Acid). Radiesse is unique as it is the FDA approved for hand rejuvenation, and can also be hyperdiluted to use for skin rejuvenation.
