In what cases is Denserty most effective?

I've been looking into Density lately, and I'm wondering in what cases it is most effective.

I wonder if it is effective for overall facial elasticity loss, or if the satisfaction is higher when concerned about specific areas like the jawline or sagging cheeks.

I'm not sure if it's high.

My face isn't particularly saggy, but I'm worried because my jawline has become less defined and I feel like my skin elasticity has decreased compared to before.

Those who have received Density What concerns did you have that led to this treatment, and in what areas did you feel the most effective results?
