Is there any synergy when performing the two procedures at once?

From what I heard from my friend, when they went for a consultation, many people recommended a combined lifting procedure that uses both radio frequency and ultrasound equipment simultaneously. What I'm wondering is... I'm worried that receiving two such powerful laser treatments at the same time might overstimulate the skin's surface, potentially causing side effects like breakouts or excessive sensitivity. I really would like to do it, though. Is the synergistic effect of performing both procedures at once really significant enough to be noticeably felt compared to the actual cost or pain investment?

I'm really curious if getting a combination treatment done at once is definitely more beneficial in terms of lifting and elasticity improvement compared to receiving them separately. I would also like to know if it is safe to receive even if my skin is thin or sensitive.
