Hi, I'm Dr.
Rajani.
Thanks for joining me today.
I'm answering the question from a viewer.
How long do dermal fillers really last?
This was someone who had a little filler in the cheek and under the
eye, and four years later said that she hasn't had any other products in
there, but it looks a little baggy.
Now, is it just aging or could it indeed be dermal filler?
If you like these videos smash that like button subscribe, and please share
them with your friends, help us grow.
So absolutely it can be filler.
But the first thing to understand is whenever it
talks about biller, what is it?
There's a whole group of what we call fake fillers or fake substances, or even
Silicon that are repackaging syringes.
So I'm talking about.
We'll assume it's legitimate product.
We talked about filler there's many different ones in terms of what
they're made of what she's referring to is hyaluronic acid filler.
The most commonly use is dissolvable and.
It is used in many areas of the face, including the underride
the lip, the cheeks can Diller be placed anywhere pretty much.
Um, it can be done.
The question is, should it be done?
So that's high allergenic acid filler.
The ones we're not referring to in this video will be calcium hydroxylapatite,
like radius, um, Bellville or P M M a type billers, or Sculptra P L L a.
Poly L lactic acid.
So cross-linked hyaluronic acid fillers.
How could it be and why?
And the question becomes if it's approved or studied for one
year duration, like many of them are they're six month fillers.
One-year fillers, uh, and up to two years.
So, so Juvederm Voluma would be FDA approved for up to two years, very
expensive study, but why wouldn't they study it to three years?
Well, you want to get the product out there every year.
You don't get it to market and you've lost millions and millions of dollars.
But if, if a product is, let's just say it's approved for one year,
the one that was used in her cheek.
Why would it be there four or five years later?
What are the reasons?
The reason is the approval study is just what it is.
It's to get it approved and they do look at duration.
But when you think about it, what gets rid of fillers?
And there's a few factors.
Number one is migration of products.
You put a product in and it might sit there, but then all of a sudden you move.
There's a lot of musculature there and.
It flattens, it moves it migrates.
Of course, filler does migrates.
That's one thing that would make the result.
Not last, necessarily more than a year in the study.
Number two is.
There's about five high-alert Iran.
Uh daises so they break down hyaluronic acid in everyone's
body to varying degrees.
So we do metabolize it and break it down at different rates.
Number three would be college and loss.
So after about a year, you look at one of those studies.
Maybe 70 or 60% result is still there.
30 to 40% is gone.
That's not enough to get an approval beyond that.
So it still leaves 60% of the product there, but we lose collagen.
We lose bone, the musculature plays a role, but you're still
let's, let's call it 60% of the product's still there at a year.
So, of course it could be there four or five years.
I've seen product lasts up to 10 years.
People come in specifically with the underwriter and it's baggy after 10 years
and they swear they haven't done anything.
Assuming it's real product, not permanent.
And they thought they were getting something else.
It is hyaluronic acid.
How do I know?
Because you can put high out here on a days in there in, in hours.
That's how long it takes.
It goes.
Now there might be a little fluid in there.
There might be the product certainly needs to be eliminated from the
body, so it can take up to a week.
But within hours you see a result from the dissolving.
You know, that indeed was hyaluronic acid filler, and anyone
who's been injecting for a long time will tell you that they've.
Dissolve filler for many years ago, the longest I had was about 10.
Um, and of course it's still in there because what is hyaluronic acid do?
It draws water in.
So even though let's say there was 20% of product left in a
delicate area, like the under eye.
Where you're going to see my new details and all of a sudden it drew water in.
And often when hyaluronic acid attracts water, it holds it.
It doesn't let it go.
You have to dissolve it.
Uh, it goes away then we know what it was.
So it lasts a long time.
You don't need a study to tell people who practice that
you don't need anything else.
We know it lasts a long time there.
You now know I put a complete playlist up here in dermal fillers.
She can watch them being placed.
You can see a lot more questions being answered.
See which ones might be or may not be right for you.
