Can Ultherapy Improve Nasolabial Folds? Hollowing vs Sagging Above

Not always. I first work out whether the fold is a hollow caused by volume loss, or a line formed by subcutaneous fat sagging from above. The first needs volume put back. For the second, once I confirm the problem involves the SMAS (the fascia layer) and subcutaneous fat, I consider Ultherapy to treat the sagging above.

Don’t jump to “how many lines”

Seeing your nasolabial folds, you might ask, “Can Ultherapy lift this line away?” I first look at how the line formed, and only then answer whether it can improve.

I separate two cases. In one, the fold area has sunk in because of volume loss. In the other, subcutaneous fat above the fold sags and forms a more visible line below it. Until these two are told apart, “having nasolabial folds” is not enough on its own to decide on Ultherapy.

Where it has sunk in, the point is putting volume back

If the main problem is hollowing, the direction is simple: the missing volume needs to be put back. In that case I don’t treat lifting as the answer to filling a hollow.

This judgment saves you money spent on the wrong treatment. First confirm that what really needs treating is the sunken part, then talk about restoring volume. Don’t use one HIFU session as a test to see whether it disappears. If the hollowing is not only at the fold but also under the cheekbones, how I split the areas is in can hollow cheeks have Ultherapy.

When the tissue above sags, it isn’t the line itself you look at

In the other case, subcutaneous fat above the fold sags and makes the boundary below look deeper. What needs judging then is how much the tissue above contributes, not just the position of the fold.

Once I confirm the sagging above involves the SMAS and subcutaneous fat, I consider Ultherapy. Where fat needs reducing, lipolysis (fat-dissolving) injections may be combined as well. The goal is to treat the tissue pressing down on the line, not to treat the groove as something a lift can fill. The treatment’s line count and cost only mean something once the direction is settled. If you have already had Ultherapy and other areas changed but the tissue above the fold still sags, see the localized-residual branch in when Ultherapy seems to have no effect.

Main situationWhat decides it
The fold itself is clearly sunken The problem is volume loss, and the hollow needs filling
The tissue above the fold is sagging downward Once SMAS and subcutaneous fat involvement is confirmed, consider Ultherapy for the sagging above

FAQ

If my nasolabial folds are deep, does that mean Ultherapy suits me?
No. Depth can't replace judging the cause. First tell whether it is a volume hollow or subcutaneous fat sagging from above.
Can Ultherapy fill in hollow nasolabial folds?
If the main problem is volume loss, the focus is putting volume back. Lifting and filling are not the same thing.
Is looking at the fold itself enough to judge it?
No. Besides whether the fold is hollow, you also have to look at how subcutaneous fat sagging above it affects the line.
What if I have both hollowing and sagging from above?
Judge them separately. Ultherapy is considered for the sagging above, and the sunken part needs volume restored separately. Don't expect one treatment to solve both.
