Some cosmetic practitioners in Australia are starting to use the double chin product in the jowl area. This is an experimental treatment at the moment and something that we will not offer until more testing has been performed.
Some patients with large amounts of loose skin may be more suitable for surgical treatment such as a lower facelift. This is not something that we offer at Cityskin but if you get in touch again by email we can provide suggestions on good people to see.
The photo below shows the jowl and pre-jowl sulcus.
How much dermal filler is needed to treat jowls?
I would estimate that you would need to use at least 2ml of dermal filler to lift the cheeks and treat the jowl/jawline. This is an estimate but you may need more depending on the laxity of the skin.
