I am in my late 30s and worried about losing cheek fat. Will my cheeks remain hollow if I get Density High?

Hello. Lately, my facial contours have been sagging, making my double chin and sagging cheeks more prominent, so I am looking into lifting procedures.

I saw reviews of the Denserty High procedure, which states that high-frequency and ultrasonic energy is emitted simultaneously. I am writing this inquiry to ask if it would be effective for my face shape.

However, since I do not have much facial fat, my biggest concern is that my cheeks might become hollow or sunken after the Density High procedure. I would like to hear the specialist's opinion on whether Density High can be safely performed given my skin thickness and fat distribution.

I would like to know the level of pain during the procedure and whether the cooling system is effective. Please recommend an approximate number of shots and provide a cost estimate.
