Quick blog, as I take these all with a grain of salt. But the interesting conclusion of this study was that RHA fillers work better on people of color (which they define by the Fitzpatrick skin color score).
I think RHA is a good dermal filler. It is the newest US HA filler on the market but has been in Europe for a while and is reportedly the #2 filler brand there. The HA fillers all vary from person to person in how long they last. So one filler may be better for you, another for a friend.
This study was “Effectiveness and Safety of RHA Dermal fillers for the Correction of Moderate to Severe Nasolabial Folds in People of Color: Post Hoc Subgroup Analyses of US Pivotal Clinical Data. “ in the April 2024 issue of Aesthetic Surgery Journal.
The premise of the study is to look at people of color- too many studies are done on white patients, who have different skin thicknesses and pigmentation issues.
Study:
- 217 patients, men and women, average age 56
- treated with RHA2, RHA3, RHA4
- Fitzpatrick skin types were recorded
- Moderate to severe nasolabial folds
- Evaluation at baseline, 6, 9 , 12 and 15 months
Findings?
- POC showed greater improvement than nonPOC at statistical levels and multiple evaluation points.
- Treatments satisfaction were similar for POC and nonPOC
- No keloids
My thoughts?
I think it was interesting they thought that people of color had better improvement than non- people of color.
I am sure this study was to show RHA is a viable filler in the American market. I studied the article in depth to try to find out how many syringes of filler were used on each patient. If people get more filler, they may see better correction, last longer, and be more satisfied.
So I don’t know that I take much stock in this study. But I am glad they are trying to broaden studies- men vs women, age issues, and differences in skin tone and color.
