I'm worried about my nasolabial folds and facial elasticity. Is Density High effective?

Lately, every time I look in the mirror, it feels like my nasolabial folds are getting deeper and my facial skin is sagging. I feel like I need to get some firming treatments, so while looking into various options, I noticed there were an unusually large number of reviews for Density High.

I want to pay for it right away because they say it addresses both elasticity and lifting at the same time, but I'm really curious if I can actually see my facial lines becoming tighter after the Density High treatment. The price is quite high, so I'm really hesitating.

Has anyone personally received the Density High treatment? I would appreciate your honest opinion on how many weeks it usually takes to feel the elasticity returning, and whether the effects of line refinement and improved firmness actually last for a long time.
