Are there any side effects such as burns or cheek hollowing after the Ondari lifting procedure?

I am concerned that my double chin area has sagged and my facial contours have collapsed, so I am looking into lifting procedures.

I learned about Ondari Lifting, which uses microwave energy to smooth the skin instead of lasers or ultrasound. However, I am becoming cautious because I heard that if the injection is excessive, it can cause side effects such as burns under the skin, sunken cheeks, or protruding bones.

I would like to honestly know if this Ondari Lifting procedure is performed safely. I am also curious if the sagging areas and the areas that need fat reduction are accurately distinguished to prevent my cheeks from shrinking too much and making me look like a skeleton if the procedure is performed blindly without considering my face shape. Will my face swell severely or bruise immediately after the procedure, making it very noticeable when I go to work?

I am also curious about the exact cost including VAT, based on the standard dosage for the On-Da Lifting procedure.
