Does the OnDaLifting fat dissolving treatment work well?

I heard that the effects of the Onda lifting appear immediately.
Can facial slimming through on-therapy lifting be achieved before a special event?
When would be a good day to receive it?
It would be problematic if there are side effects such as swelling or bruising on the face.
I'm curious about how many days the downtime lasts after the procedure.
Do you have any information about On-Da-Lift or have you ever received On-Da-Lift?
