Unfortunately a lot of pricing involves promotional prices/trial prices etc.
The areas covered also differ (for the stated price)
Ulthera is the most known brand - but due to high consumables costing and machine costing, each treatment is $3400 and up usually.
HIFU (korean machines) tend to range from $1200-$2500 and depends on the experience of the doctor. Talk and discuss with your doctor thoroughly before deciding.
