How long does a density high last?

I want to refine my facial contours, but I'm a bit scared of thread lifting, so I'm looking into laser lifting. Among them, I heard that Density High is effective for tightening skin using radiofrequency energy. What I consider most important is longevity, so I would like to know how long the effects of Density High typically last.
Do the results of Density-High usually last for more than six months after a single treatment? Or do I need to get it done once every quarter to maintain optimal condition? If anyone was satisfied with the Density-High procedure or says the effects lasted longer than expected, please share your thoughts in the comments!
