Acupuncture also stimulates the fibroblast cells to up the production on these components. In addition to using acupuncture needles, I often use low power laser or electric stimulation. By using the laser, I can insert a few needles and still stimulate all the other facial points. You do not feel the laser at all. It is not dangerous unless you look directly into it for an extended period of time.
Electric stimulation can give mild or quite strong stimulation.
It feels like a low level buzzing. Small clips are attached to needles and the stimulation is adjustable. It increases the speed of noticable results. It is also safe and not painful. I use herbs both externally in the steam and internally.
