Why is Radiesse diluted for skin quality?

Hearing that Radiesse is diluted for skin quality raises a fair question about why. If you are weighing it in Mamaroneck, Larchmont or elsewhere in Westchester, here is what the published research says.

What the research reports

A paper indexed in PubMed Central says that "diluting CaHA-R into a range of lower G ′ values may closely emulate the rheology and feel of subcutaneous fat."

CaHA is short for calcium hydroxylapatite, the Radiesse ingredient. The paper's point is how the diluted product feels, and the word it uses is "may".

More reading on the ingredient

Several papers look at calcium hydroxylapatite in other settings. A systematic review of calcium hydroxylapatite and aesthetic outcomes in controlled clinical trials collects the trial evidence. A study of volumization and global biostimulation with calcium hydroxyapatite filler for hand rejuvenation describes a dual approach, and an expert consensus on calcium hydroxylapatite for buttock augmentation sets out best practices. A report on radiographic manifestation of cosmetic hand rejuvenation with calcium hydroxyapatite looks at the ingredient on imaging.

Questions to put to your injector

Dilution is a decision made for a specific person and area. Ask which product they plan to use, whether they will dilute it, and why. Have them note the product name and treatment date for you.

What to leave alone

Do not try to dilute, mix or adjust any product yourself, and do not judge a result from a description in a paper. If the treated area looks or feels wrong afterward, phone the clinic that treated you.

The follow-up people ask

Many readers next ask how it differs from Sculptra, so bring that question to your consultation.
