How long do bruising or redness last after Ultherapy?

I am curious about how long symptoms like bruising or redness usually last after an Ultherapy procedure. I heard that some redness is possible immediately after the treatment, but I am wondering if it tends to go away after just the same day, or if it can last for a few days. If I have skin that bruises easily, could it last longer? I would appreciate it if those who have actually received the treatment could share how much redness or bruising they experienced and how long it typically took for it to subside. I know there is individual variation, but I am curious about the general duration.
