Has anyone had an endoscopic forehead lift?

My eyebrows/forehead are always heavy, so I feel like my eyes are being pressed, and
 when I don't have an expression on my face, I've even been asked, "Are you mad or why are you frowning?", so
 I was thinking about getting an eyebrow thread lift, but I heard that thread lifting isn't very effective and doesn't last long, so I just got an endoscopic forehead lift. I'm looking into it, but
 some people say it's too early to do it in your 20s.
 Anyway, like double jaw, the muscles are separated from the bone and fixed, right? So, I wonder if it will sag like Western music, and
 there are not many reviews from people who have done it themselves or their impressions from acquaintances after seeing it,
 so I am posting a question to Seongyesa.
