How intense is the effect of a high intensity?

Recently, I felt like my skin was losing elasticity, so while looking into lifting procedures, I learned about Density High.

I heard that Density High is a procedure that uses high-frequency energy to help stimulate collagen production deep within the skin. I am curious to know what kind of results I can actually expect. In particular, is it possible to improve sagging jawlines or fine wrinkles through Density High?

I would also like to know if Density High is effective after just one session, or if repeated treatments are necessary. I would appreciate it if you could explain the generally recommended number of sessions and whether the recommended number varies depending on an individual's skin condition.

Since it is important to know if there is any interference with daily life after the procedure, I would like to know about the recovery period and the extent of reactions such as swelling and heat sensation. As this is my first time considering Density High, I am also thoroughly aware of any side effects or precautions. Finally, I would like to know the expected duration of the results from Density High and the most effective care methods when undergoing the recommended number of sessions.
