How is the duration of Density High maintenance and satisfaction?

hello.

I am an office worker deeply worried that whenever I look in the mirror, my facial lines don't look the same as they used to due to sagging skin, possibly caused by my age.
I feel like I need to take care of my face now, so I want to refine my facial contours,
I am a bit afraid of side effects like pain or dimpling from thread lifting because of the thought that needles or threads are inserted directly, so I am actively looking into laser lifting.

I asked around and heard that among them, Density High is effective in tightening skin elasticity from deep within by precisely using high-frequency energy.
I am leaning heavily towards this because I heard that the pain is relatively minimal and the cooling system is excellent, so even a timid person like me can receive the treatment comfortably.

However, when choosing a procedure, the most important thing for me is its longevity.
I would like to know exactly how long a intensity high usually lasts.
Since the price range is on the higher side, I am being cautious about how cost-effective the results will be.
Usually, after receiving Density High once, do satisfactory lines tend to last for more than half a year?
Or I am wondering if I need to receive it periodically, once every quarter, to maintain the tight effect and stay in optimal condition.

In fact, those who were satisfied with the improvement in elasticity or skin texture after the Density High procedure at a dermatology clinic, or
If you have any reviews saying the effects lasted longer than expected, please be sure to share your valuable information and tips in the comments!

I wish I had a face like this haha
